The first test launch of the unified supercomputer infrastructure based on the National Research Computer Network of Russia (NIKS), which includes the object of the scientific infrastructure of the JINR Member States — the Govorun supercomputer, has passed. http://www.jinr.ru/posts/obedinennaya-superkompyuternaya-infrastruktura-na-baze-niks-zapushhena/ https://nauka.tass.ru/nauka/13533967 These resources will be available for use by all members Read more…
For efficient data processing of the MPD experiment, a heterogeneous, geographically distributed computing environment is currently being created on top of the DIRAC Interware. By 2019, standard workflow tests related to general Monte-Carlo generation were successfully carried out, which proved the possibility of using DIRAC for real scientific computation. At Read more…
One of the problems to be solved in modern high-energy physics experiments on particle collisions with a fixed target is the visual representation of the events during the experiment run. Event display system can be used at the design stage of the detectors for: model and reconstruction algorithm checking and Read more…
The ROOT geometry package is a tool to build, browse and visualize detector geometries. It is independent from any tracking Monte Carlo engine, though it has been designed to optimize particle transport in correlation with simulation packages as Geant3, Geant4 and Fluka. The building blocks of any geometry are the Read more…
Event reconstruction is the process of interpreting the electronic signals produced by the detector to determine the original particles that passed through, their momenta, directions, and the primary vertex of the event. Event reconstruction consists of the following main steps: Hit reconstruction in subdetectors; Track reconstruction usually composed of: Searching Read more…
MPD simulation includes interactions and particles of interest, geometry of the system, materials used, generation of test events of particles, interactions of particles with matter and electromagnetic fields, response to detectors, records of energies and tracks, analysis of the full simulation at different detail and visualization of the detector system Read more…
Event generators are software libraries that randomly generate high-energy particle physics events. MonteCarlo (because they exploit Monte Carlo methods) event generators are essential components of experimental analyses today and are also widely used by theorists and experiments to compare of experimental results with theoretical predictions and to make predictions and Read more…
Basically, there are two ways to simulate the behavior of a system: either one can describe its evolution analytically, in which case computers are used to find the solution of the dynamic equations, or a probabilistic approach is used, in which at each step pseudo-random numbers are used to select Read more…
Macro is a main executable element of the MpdRoot environment. Usually it has .C extension. You can find in the ROOT documentation instructions on how to run macro by ROOT interpreter (CINT). We have currently two directories: “macros” with refactored macros and the old MpdRoot “macro” directory, containing macros that Read more…
