DEVELOPMENT OF TRIGGER SCINTILLATION COUNTERS FOR THE MULTI-PURPOSE DETECTOR MPD OF THE NICA PROJECT

The paper considers the design and characteristics of trigger scintillation counters based on silicon photomultipliers and fast scintillators. The experience of designing such devices is described and the results of research on development indicators are presented.

Lattice Study of QCD Properties at the “Govorun” Supercomputer

This report is devoted to Lattice QCD simulations carried out at the “Govorun” supercomputer. The basics of Lattice QCD methodology, the main Lattice QCD algorithms and the most numerically demanding routines are reviewed. We then present details of our multiGPU code implementation and the specifics of its application on the “Govorun” architecture. We show that implementation of very efficient and scalable code is possible and present scalability tests. We finally relate our program with the goals of the NICA project and review the main physical scenarios that are to be studied numerically.

Development of the Geometry Database for the BM@N Experiment of the NICA Project

The article is dedicated to the current state of the Geometry Database for the BM@N experiment of the NICA project. The main goal of the database is to provide a central storage of the BM@N geometries, convenient tools for managing its geometry modules, various software assembling versions of the BM@N setup as a combination of modules and additional files providing support for a set of versions. Both the Graphical User Interface (GUI) and the Application Programming Interface (API) have been developed.

High-Performance Optimization of Algorithms Used in the BM@N Experiment of the NICA Project

Results of high-performance optimization of BmnRoot software modules are presented. The BmnRoot package used in the BM@N experiment of the NICA project plays a crucial role in the simulation and event reconstruction so its performance should be maximized to make the data processing efficient. Results of performance analysis on representative testcases are given and bottlenecks are localized. Most suitable approaches to BmnRoot optimization are chosen and numerical estimates of the scalability of the parallelized modules for event reconstruction are presented.
