ROOT - Is A High-Performance Computing Platform

ROOT

ROOT is a high-performance computing platform designed for particle physics. Its users process petabytes of data annually. Its main applications include high-energy physics data analysis and acquisition. Its C++ interpreter allows users to run the program in interactive, scripted, or compiled mode.

SELinux

SELinux is a security system that applies a context type to all files and directories on a system. This system has many configuration options, such as enabling or disabling SELinux completely. It can also be configured to add or remove functionality from the kernel.

SELinux is based on the principle of least-privilege. By default, it denies everything except for services that are required by the system. If you want to grant a service, you must define a policy based on a specific set of rules. Because of the strict policy, this system can pose a number of problems for the system administrator and end users alike.

SELinux is part of the Linux kernel and aims to protect the system against unauthorized use. It does this by detecting and denying access to various kernel resources and operations. SELinux is implemented as hooks, which are part of kernel code. Since root calls functions in the kernel, SELinux can deny access to those functions if the context is not secure.

This system requires troubleshooting tools. Some packages don't provide these by default. In addition, SELinux relies on labels, which are stored as extended attributes in the file system. Non-file objects are managed by the kernel, and administrators must write rules to allow them to continue running.

SELinux can also cause problems on the server. When SELinux is enabled, other processes will not be able to generate contexts for files. By default, this will result in the system limiting access to files.

SELinux supports attributes for types, domains, and daemons. These are assigned to types that will act on the system. Policies can be generic and can be applied to all users or only to certain domains.

SELinux supports the concept of permissive types. This means that administrators can put a domain into permissive mode without setting the entire system to permissive mode. This feature is much more flexible than setenforce 0, which puts the whole system in permissive mode.

One major disadvantage of SELinux is its complexity. Linux systems are generally very complex and are easily abused by intruders. As a result, users need to be very careful in setting up SELinux. The AppArmor project provides a simplified implementation, which simplifies the process of implementing this security technology.

The SELinux for ROOT project is free, open source, and aims to make Linux more secure. Its modularity allows developers to build third-party services that integrate with SELinux. You can browse the list of modules that SELinux uses by typing semodule -l.

The SELinux security server generates messages that are associated with items. These messages are sent to userspace programs that use SELinux. These programs are called userspace object managers. The D-Bus and systemd are examples of such programs.

Apparmor

ROOT is a digital adaptation of a popular tabletop board game. The game is a war and adventure game that features 2 to 4 players battling for control of a vast wilderness. There are a variety of gameplay options and several deckbuilding options.

ROOT is highly optimized for high computing efficiency, and it can process petabytes of data per year. It is designed for Linux, macOS, and Windows systems, and it includes a C++ interpreter. It also integrates with Python and Jupyter notebooks seamlessly.

ROOT

In ROOT, players take on the role of a single character or a group of players who play as different factions. Each faction has its own abilities and win conditions. Players can use different types of tools to solve problems and solve the narrative. The game features beautiful multi-use cards and a variety of role types that allow for unique game play. ROOT is not a beginner game and requires some knowledge of programming languages.

ROOT was created with high computational efficiency in mind. In fact, it is used by particle physics teams to process petabytes of data each year. Its specialized design makes it a perfect fit for this type of research, and the ROOT C++ interpreter is available for both interactive and scripted use. It even supports Jupyter notebooks!

In operating systems, the root directory is the topmost directory. This directory contains all files and folders. The root directory is generally designated by a forward slash (/), though back slashes are sometimes used. The term "root" comes from a tree-like organization of files, where the root is located at the top.

Root QTL are excellent candidates for marker-assisted selection. They show a significant potential for drought tolerance and plant productivity. However, it is important to note that the traits of selected roots can vary greatly depending on the environmental conditions and the ultimate goal of the researcher. Moreover, many previously reported markers for root traits were confounded by inconsistent phenotyping and minor contributions to the trait of interest.

Once rooted, Android users will have a host of customization options, from removing unwanted bloatware to overclocking the processor. Despite the benefits of rooting, it can be a confusing process. You can use ROOT to root your device, but remember that you should be sure you are aware of the risks associated with it.

Root servers are located at different locations throughout the world. Root servers are issued a numeric IP address that can be reached by DNS queries. This allows users to use a single IP address to access many different websites, despite the fact that they are not physically in the same location.

A ROOT Guide For Beginners

There are a lot of advantages to rooting your Android device. Rooting your device will allow you to install a lot of cool apps and customization options. It also gives you access to advanced features like TMVA (multi-variate analysis) and TTree (large data volume implementation). Read on to learn more. You'll have a lot of fun! But be careful! Rooting your phone may damage the device's performance.

TChain class

In A ROOT Guide for beginners, the TChain class is introduced. This class provides an interactive and flexible programming interface. It also includes a graphical user interface (GUI), which allows you to see your data in a graphical manner. This class is designed to be a beginners' guide that lays the groundwork for more advanced applications in future work.

The TChain class is the underlying abstraction for TCling. It is a general interface to the underlying Operating System. This system can be TUnixSystem or another Linux system. In addition, there is a gInterpreter, which is the entry point to the ROOT interpreter.

The TChain class is built on the TGraphErrors class from the ROOT programming language. It defines a function, window, and legend. The constructor accepts a pointer to the f function, which provides a variety of line styles. The output will also show parameters and other vital information. This class is one of the most basic classes in the ROOT language.

Using the TChain class is easy. It is a lightweight programming language and you can use it in conjunction with other language classes. You can also use macros. One macro can contain multiple variables, which are stored in separate files. A macro can also be loaded with the slits() function.

Histograms are very important in physics and data reduction. ROOT has several classes for representing histograms. Most inherit from TH1. Bi-dimensional histograms use floating-point numbers. The first three lines define the function and set the parameters. The next line creates the histogram. The example histogram contains 100 bins, each equally sized.

There is also a GUI for browsing ROOT objects. This is a convenient way to explore ROOT objects. However, it is limited in functionality. This interface is useful for debugging, quick hacking, and testing. In addition, ROOT supports advanced mathematical functions, which live in the TMath namespace.

TNtuple::Fill() accepts only floats

The TNtuple class allows the user to create n-tuples of arbitrary type. The Fill() method of the TNtuple class fills the current values of the connected variables. This method is useful for large tree structures where a small number of items is required.

TNtuple::Number::Fill() accepts n-tuples of arbitrary type

The TBranch class in ROOT is capable of storing n-tuples of any type, so long as the items are of the same type. For example, if we create an array with n-tuples of type float, we can use the Fill() function to fill the n-tuple with the float values in the array. We can do this using the following macro:

The histogram function is a tool provided by ROOT. The tool provides a graphical user interface (GUI) that lets you analyze data interactively. The GUI is intended to be a beginner's guide to ROOT. It gives examples of typical student lab problems and lays the foundation for more advanced applications in the future.

N-tuples are a common data type in applications. The data structure of such objects is similar to that of event data. However, the API for N-tuples differs. The data structure of n-tuples is tree-based. The N-tuple service supports an inheritance model. This allows you to use it to load and store N-tuples of arbitrary type.

The n-tuple format is similar to the histograms in the same way. The difference is that the N-tuples are stored in a different output file. For example, when an N-tuple contains three independent variables and one dependent variable, the data is stored in an n-tuple. The data structure is then written to the data file by using a Gaudi sequencer. The sequencer calls a series of algorithms to process the data. If one of the algorithms fails, the execution may stop. An address tag is defined in the algorithm header file. The tag should be declared just like any other tag and should be named "Address".

Another important feature of ROOT is the ability to apply compression algorithms to n-tuples. This reduces the amount of memory consumed. A single value will take up little disk space, but it must be decompressed on reading. The user should carefully consider the design of n-tuples and the nature of the analysis before applying compression algorithms. For instance, if the data is large, it is better to keep the n-tuples simple and avoid double precision.

In addition, n-tuples can span multiple files. In ROOT, this is accomplished by using the TChain helper class. You can use the constructor to pass a TTree or TNuple as the file name. Then, you can add multiple TChain files by using the Add(fileName) method. Wild-cards are also supported.

Rooting Android gives you access to cool apps and customization options

One of the best features of rooting your Android device is the ability to add new features and functions that are not available in standard Android versions. This can be done by installing a custom kernel, which is a modified version of the firmware that controls communication between software and hardware. For example, a custom kernel called ElementalX can add the Sweep2Sleep feature to your Android device. In order to enable this feature, you must unlock your bootloader and flash the custom kernel.

The downside of rooting Android is the risk of bricking your phone. If you push components too far or install unsupported firmware, you can damage or completely brick your device. Before you start rooting your Android device, make sure that you are sure you're ready to take the risk.

Rooting your Android device also gives you access to hidden folders and important files. You can also install custom kernels that are available only for rooted devices. These kernels can improve battery life, battery charging, and performance. By modifying the kernel, you can add new features and apps that you never knew existed before.

Another benefit of rooting your Android device is the ability to download apps from any source you wish. The Google Play Store has more than 2.5 billion apps, but there are some cool applications that can only be downloaded when you root your device. Those apps include Substratum, DriveDroid, and DiskDigger, to name a few. Once you root your phone, it will run at a much faster speed than an unrooted device.

Rooting your Android device also allows you to see who has access to your network. Once you root, you can ban these people from your network. This feature is also available on newer Android phones. If you're looking for a cheap phone, there are several rooting solutions available.

Another benefit of rooting is that you can flash a custom kernel to your device. These kernels can be either ElementalX or Franco Kernel and allow you to overclock the CPU for more power or underclock it for better battery life. You can also adjust display and vibration settings.

What is ROOT Framework?

If you are looking for an open source framework for data analysis, then this article is for you. This framework includes Data container, Object Oriented, and C++. It is used to create analytical and interactive applications. ROOT framework aims to give you the freedom to create applications using the latest open source technologies.

Open-source data analysis framework

If you're interested in big data analytics, you might be interested in the open-source data analysis framework, Ibis. Developed by Cloudera, Ibis provides a 100% Python user workflow on top of big data systems. Many data scientists use Python, but it has limitations when it comes to big data, and Ibis seeks to eliminate this problem.

Several libraries are available that allow you to use different methods of statistical analysis. Some examples include 2DMAT, a framework for experimental measurements of two-dimensional materials. Other analysis tools include Bayesian optimization, grid search, and replica exchange Monte Carlo. These libraries enable you to do a variety of statistical analysis, from linear to nonlinear data.

One open-source data analysis framework, jHepWork, is a component-based data mining tool. Its GUI allows you to create interactive reports using CSV and JSON data. The tool also supports filtering, sorting, conditional formatting, and calculated values. You can also export your web report to Excel, PDF, or HTML.

Data scientists are increasingly leveraging open-source tools to build data frameworks. These tools streamline workflows, allow for real-time analytics, and provide storage and access to large data sets. Open-source tools such as Python and PHP can help data scientists build data frameworks that make the most of existing data sets.

Open-source data analysis frameworks such as Pyphant, which uses HDF as its native file format, are also a good choice. They are free and easy to use, and often include the ability to perform data modeling.

Data container

The ROOT framework provides a number of different data types and containers. There are lists, ordered collections, hash tables, maps, and more. These data types can be grouped into various top-level categories. This tutorial will provide an overview of these options. This tutorial will use concrete examples to help you understand how to use the framework.

ROOT also offers a variety of data analysis features. It includes a graphical user interface for interactive data analysis. The GUI is designed as a beginner's guide to data analysis and provides a few examples that are commonly used by students. These examples lay the foundation for more advanced applications in the future.

The GUI enables you to navigate and use ROOT data containers. By double-clicking an object in a collection, you can perform the default action associated with the object's class. For example, if you double-click on a histogram object, it will display a histogram of the distribution of its entries. Alternatively, you can right-click an object to access its context menu.

A data container is a collection of data assets from different sources. These data are organized in a hierarchy based on classification. They may be organized by department, function, or consumer group. This hierarchy makes it easy for a team to store different types of data with different security levels. For example, they might need a general folder to store all of their datasets while a sensitive folder is designed for more sensitive information.

Object Oriented

ROOT is an object-oriented C++ framework. It is designed for high-performance computing. Its users need to process petabytes of data every year. Its primary applications are in particle physics and data analysis. It is used to create many of the latest experimental plots in high-energy physics. It includes a C++ interpreter, a graphical user interface builder, and object serialization and persistence.

The ROOT system contains a rich set of GUI classes that provide full OO-GUI support. The basic concept is that a GUI is a simple wrapper of data, which is stored in a data container called a tree. All GUI elements are drawn by using the low-level TGXW abstraction base class, which inherits from TGWin32. The implementation of TGX11 requires X11 and Xpm libraries.

A number of flaws in the ROOT framework make it difficult to use, particularly for beginners. Some of these issues include heavy use of global variables and an overly complex class hierarchy. However, these flaws are discussed regularly in the ROOT mailing list, and the ROOT team works to resolve them as they are discovered. For example, the CINT interpreter has been replaced by Cling, and numerous other bugs have been addressed since the original release of ROOT.

The ROOT system is a powerful C++ library that can handle large amounts of data. It also has a powerful C++ interpreter and advanced statistical analysis and visualization tools. Users can interact with the system through a GUI, batch scripts, or a command line. In addition to the GUI, the ROOT C++ interpreter can be used to interact with the system.

C++

The ROOT framework is a C++ library and object-oriented programming language. It was originally designed for particle physics data analysis, and contains many features specific to this discipline. However, it is also used for data mining and astronomy. Its latest minor release is 6.26. It is free to download and use.

One of the features of the ROOT framework is its support for n-tuples. This object-oriented data structure allows the user to store objects that are composed of three independent variables and one dependent variable. Moreover, this object-oriented data structure can be strewn across different file systems, including local disks, the web, and shared file systems.

The ROOT framework provides a graphical user interface (GUI) for interactive data analysis. The GUI is designed to be user-friendly and act as a beginners' guide. It provides examples of typical student lab problems and lays the groundwork for more complex applications in the future. It is also a great choice for new users who want to learn more about the ROOT framework.

Using the ROOT framework, developers can easily load and use C++ scripts. For example, a macro can be used to run a command and the result should be the same as a standalone application. The ROOT framework also provides the ability to compile the source code for a macro. This can improve performance and bring the macro closer to the production environment. Once a macro has been compiled, it should appear similar to Figure 2.2.

ROOT is a library and object-oriented program written in C++. Its original goal was to help scientists analyze data from particle physics. Today, thousands of physicists use ROOT applications.

Snaps

Snaps are portable software applications that are run from the ROOT framework. They are fast and secure and are sandboxed. They run under various confinement levels, and have different interfaces to access system resources. They are configured according to the level of confinement and can be updated automatically. They have a small footprint on the system and are very bandwidth efficient.

Snaps are installed as a package in ROOT framework and they can be installed using sudo snap install root-framework-edge. They are automatically updated via delta patches. You can also use sudo snap install root-framework --edge to install the nightly build. This is a convenient way to get the latest version of any package without having to upgrade your operating system.

You can easily install the ROOT framework using the command line or using the snap installation on your system. ROOT is compatible with many popular operating systems, including Ubuntu and Mac OS X. Its main goal is to provide a Docker-like experience for users, blurring the boundaries between host and container environments. The ROOT desktop icon can be added to the start menu.

The biggest disadvantage of snap packages is that they tend to be larger than traditional packages. That's because snap packages contain all of their dependencies, and many programs will share the same dependencies. As a result, systems that have a lot of snaps will end up wasting a lot of storage space on redundant data. Fortunately, today's entry-level systems often include terabyte hard drives.

When using snaps in ROOT framework, you must ensure that your output files are saved to a directory. The $SNAPDIR variable contains the path where the output should be saved. In addition, you must compute the size estimation for the data during the first pass. This size estimation will be written to the file pointed to by $SCRIPTSIZE. This file should be saved in decimal. Finally, the Snap will also pass a path to a log file containing debug data.

What is the ROOT of Data?

ROOT is an object-oriented programming language and library for analyzing data. Originally developed for particle physics data analysis, ROOT has been used in other fields as well, including data mining and astronomy. Its latest minor release, 6.26, was recently released. Read on to learn more about ROOT and how you can use it to analyze your data.

Cling is an interpreted language

Cling is an interpreted language for C++, written in C. Cling converts a user transaction into a valid C++ statement. To do this, it marks the statement as special and attaches complex template machinery. It also attaches an expression printer. The printer machinery is extensible, allowing it to print user-defined types. It also provides an interface that contains information about the printed type.

The paper is organized into six sections: the background section introduces the concepts and tools that are important to building an interactive interpreter. Next, a section on related work describes tools and technologies for building interpreters. This section also describes a general approach to the read-evaluate-print-loop concept and shows a few examples of tools in the literature. The Cling overview section introduces the set of technologies used to develop Cling. The Cling in a nutshell section is divided into two subsections: one for generalizing the properties of interactive interpreters and the other for demonstrating the properties of Cling.

Cling is a highly complex piece of software. It combines the features of a standard C++ compiler with interpreter-specific C++ extensions. This software also features an internal set of commands that enable users to easily manipulate and compile user code. Moreover, it supports incremental compilation, JIT, and reusable compilation phases.

Cling was created by CERN as a part of the ROOT project and is an interpreted language. It is an implementation of C++ and was inspired by C++, and covers 95% of ANSI C and 85% of C++. Its syntax is more flexible than those of either of those languages. Furthermore, the language does not require a semicolon in command-line statements, unlike C++.

C++ and Cling are similar in their language syntax, but C++ is more powerful and supports a larger number of language constructs than Cling. However, C++ does not support Cling's shortcuts and cannot use Cling's C preprocessor symbols. For example, a single C-language symbol, __ROOTCLING, is defined in rootcling.

Another feature of Cling that enhances its scripting experience is the introduction of dynamic scopes. This feature is especially useful for frameworks that embed Cling. An example of this is opening a serialized C++ object and accessing or calling its members. This process is not possible before runtime, so the compiler is unable to determine what it is executing. The compiler will give an error if it cannot access the file.

The migration from C++ to Cling is a complex process, and it involves re-implementing a number of interfaces. One concrete change plan involves reducing the dictionary size and incorporating a JIT compiler. This will eliminate the need for a call stub section and reflection information. It will also eliminate the need for compiled dictionaries.

Cling is a scripting language

Cling is a scripting language that consumes input and produces code for each correct construct. It also implements a user transaction caching mechanism and repairs intermediate compiler data structures. It transforms the input at the textual level and passes the code to the compiler library. The result is executable code.

Cling is a C++-based scripting language. Its syntax is similar to C++, but it is written in an interactive language. It is used for data serialization. It has the ability to prevent session crashes and discards invalid code. Cling is used by ROOT, which stores data in binary format. It is also capable of displaying the contents of loaded data files.

Cling is a complete C++ interpreter that uses the Clang and LLVM compiler platforms. Unlike Cint, Cling is a full-blown C++ interpreter. Its LLVM and Clang support means that it is much faster than Cint. Moreover, Cling can be extended by using plugins. It also supports domain-specific capabilities.

Cling also enhances the C++ language through dynamic scopes. This feature is particularly useful in frameworks that use C++. For example, a common scenario in ROOT is opening a serialized C++ object, accessing its members, and calling its methods. Without dynamic scopes, the compiler will not be able to know the contents of the serialized object until runtime, and it will error.

Cling is a command-line language

Cling is a command-line language that can query C++ code. Cling's lookup facilities assume that the caller knows what he's looking for, and return information that makes sense in C++. Python, by contrast, must loop through every possible entity in order to report a result, making it inefficient. The language also lacks shortcuts, which can make it cumbersome to write complex programs.

Cling is an alternative to CINT, based on the ROOT data analysis framework developed at CERN. The framework is used for many current particle physics experiments. Cling parses and runs all the same types of programs as Clang, but it also supports C++ extensions that Clang cannot. It also has a production-grade parser and a separate execution engine.

Cling can also be used as a library for third-party frameworks. Cling can accept partial input, but it ensures that the compiler process is always running. It also provides an API to access recently compiled chunks of code. Additionally, it can perform custom transformations on each chunk before execution. In addition, Cling orchestrates the Clang and LLVM infrastructure.

Cling is a powerful interactive C++ interpreter. It supports the full C++ feature set, including templates, lambdas, virtual inheritance, and more. It is built on top of the LLVM and Clang compiler infrastructure and promises to improve productivity. It's an ideal choice for researchers and developers looking for a more interactive environment.

Cling has extensions that allow you to work around its limitations. Cling's preprocessor symbols are also defined, which make it possible to write extensions that work around the language's limitations. These extensions are useful for extending C++, as well as for extending ROOT functionality.

Cling is an interpreted version of C/C++ that can do nearly everything that a C program can do in user space. Cling also supports REPL functionality, which is particularly useful for fast prototyping and debugging. This means that you can use cling as a replacement for C++ in performance-sensitive applications.

Cling is a C++ interpreter based on LLVM and Clang. It provides an interactive environment for developers looking for a fast and easy way to run C++ code. It includes features such as read-eval-print loop and Emacs bindings.

ROOT - Analyzing Petabytes of Data Scientifically

ROOT is an open source framework that enables scientists to analyze petabytes of data scientifically. The framework consists of 3000 classes organized into 110 plugins and packages. It supports multiple platforms and can be built with Subversion, configure, and make. The open source project is a community effort; users contribute code and help develop new features and functionality.

CINT C/C++ interpreter

The CINT C/C++ interpreter is an open-source library designed for scientific analysis of petabytes of data. This library has a flexible I/O framework and enables users to call helper functions on objects in memory using only their type name and memory address. The C/C++ interpreter also supports the use of existing C++ libraries and can be used to interface with them.

The CINT C/C++ interpreter is designed to be flexible and fast. The interpreter can process C++ statements from the command line, dynamically define class definitions, and load libraries and source files. It also includes a built-in debugger for complex C++ code and a text-based class browser. The C++ interpreter can work on multiple operating systems and supports NextStep.

Because the C++ interpreter has an optimized bytecode engine, users can run their programs quickly. CINT also eliminates the edit, compile, and link cycle that is common with other interpreters. In addition, scripts and programs can be compiled into machine code, which means they'll perform at full machine speed.

For C++, ACLiC automatically builds a shared library and CINT dictionary from C++ scripts. It uses the same compiler options as ROOT but does not require exiting the program. The user must include class and function definitions in the script. The script can be loaded into the shared library using the.L command or by specifying the file name in the command line.

Another option in CINT is the use of ROOT macros. This allows users to create macros step-by-step using the C++ interpreter. After the script has been developed, performance is a priority. Hence, conversion to compiled code is the first optimization step. However, the user can continue to use ROOT interpreter as well.

Object-oriented C++ framework

ROOT is an object-oriented C++ framework that was developed for the high-energy physics community to facilitate efficient storage and analysis of petabytes of data. It provides a way to store any instance of a C++ class into machine-independent compressed binary files. ROOT also features an object container called TTree, which is optimized for statistical data analysis on large data sets. This container is scalable and can span a network of shared file systems, local disks, and the web.

ROOT is primarily used for scientific computing, and its speed and flexibility make it an excellent choice for data analysis. Its high computing efficiency is essential for analyzing petabytes of data every year. Most recent experiments in particle physics use ROOT to analyze their data. The framework comes with a C++ interpreter that can be used in interactive, scripted, or compiled mode.

Virtual Monte Carlo interface

ROOT's popularity is based on the fact that it is easy to use and has many features that make it a useful tool for scientific analysis. These features include an interactive C++ interpreter, high performance I/O, statistical libraries, and a graphic representation of results.

To analyze large quantities of complex data, advanced mathematical and statistical methods are needed. This is where the ROOT Math libraries step in and provide a cohesive set of statistical and mathematical libraries for High Energy Physics. By using these libraries, scientists can simulate, reconstruct, and analyze petabytes of data scientifically.

The PROOF system is a distributed physics analysis framework characterized by three properties: it is flexible, scalable, and adaptable. Its architecture is multi-tier and consists of a master node and slave nodes. Each node executes ROOT sessions on one or more computer clusters. The slave nodes are connected to each other via sockets.

ROOT also offers many statistical analysis methods and functions aimed at physicists. Its statistical analysis libraries include RooFit and RooStats. These libraries enable users to create high-quality graphic plots and store results in important formats. The ROOT codebase has been designed for multithreaded parallelism, and it covers many of the critical operations.

The ROOT file format allows for unlimited levels of directories. Files are written in sequential order, and the header of each file contains a pointer to the first element of the linked list of data objects. In addition to this, files are compressed by default using LZ4 compression.

Multivariate data analysis with ROOT

Multivariate data analysis is a powerful technique that can analyze and display sets of data. The TMVA package5 provides a range of multivariate classification algorithms that include boosted decision trees and rule ensemble fitting. This powerful package can handle data sets of any size, and can be used to analyze a wide variety of datasets.

ROOT is written in C++ and is a powerful statistical analysis and visualization tool. It can handle more than 1 exabyte of data, which is impressive for a software program. It can run on a variety of operating systems, including Linux, macOS, and Windows. The program is also free and open source. It also comes with a C++ interpreter and integrates smoothly with Python and Jupyter notebooks.

ROOT is designed for high computing efficiency. It can handle petabytes of data per year and is used primarily for data acquisition and analysis in particle physics. It is used to create some of the world's most popular experimental plots in high energy physics. It can be used in interactive, scripted, or compiled modes.

ROOT can fit binned or unbinned data with parametric functions. It represents plottable functions as classes called TF1, TF2, and TF3. These classes can be pre-compiled user code or mathematical expressions. A parser is included in ROOT to parse mathematical functions.
