摘要
正在 JINR 的 NICA 对撞机上建造的 SPD(自旋物理探测器)探测器每年将产生数万亿个物理事件,估计数据量达数十 PB,这使它与大型强子对撞机的实验不相上下。尽管该物理设施正在建设之中,但在离线数据存储和处理系统的设计阶段就必须考虑到这些数据。物理小组对进行这类计算所需的计算能力不断增长,已经占用了 JINR 计算资源中相当多的处理器时间。本文介绍了建立 SPD 实验数据存储和处理管理系统的工作情况。
The SPD (Spin Physics Detector) detector, being built at the NICA collider at JINR, will produce trillions of physics events per year, estimated at dozens of petabytes of data, which puts it on a par with experiments at the Large Hadron Collider. Although the physics facility is under construction, these figures must be taken into account now, at the design stage of an offline data storage and processing system. The needs of physics groups in computing power for carrying out such calculations are constantly growing and already occupy a fairly significant amount of processor time on the computing resources of JINR. The status of work on building a system for managing SPD experiment data storage and processing is presented in this article.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
