Abstract

The BmnRoot framework is one of the most important software tools which are used in the Baryonic Matter at Nuclotron (BM@N) experiment of the NICA project. It consists of modules intended both for simulation of detectors and analysis of experimental data. Most of tasks which are solved by the BmnRoot are CPU time-consuming so performance optimization of the BmnRoot is necessary. In the present paper results of performance study for the BmnRoot software package are presented. Bottlenecks of performance are localized and various approaches to performance optimization are discussed such as algorithmic one and parallelization. Estimates of efficiency and scalability of the software are also given.

BM@N NICA实验中模拟和事件重建软件的性能优化

摘要

BmnRoot 框架是 NICA 项目的重子物质在 Nuclotron (BM@N) 实验中使用的最重要的软件工具之一。它由用于模拟探测器和分析实验数据的模块组成。BmnRoot 解决的大部分任务都是 CPU 耗时的，因此需要对 BmnRoot 进行性能优化。本文介绍了 BmnRoot 软件包的性能研究结果。性能瓶颈是本地化的，并且讨论了各种性能优化方法，例如算法和并行化。还给出了对软件效率和可扩展性的估计。
