The service support system provides the following:
- computing service,
- storage services,
- GRID systems,
- data transfer services ,
- information service (monitoring services: servers, storage, data transfer, information sites).
The Slurm workload manager is used to launch data processing tasks. The grid environment uses Advanced Resource Connector (ARC), a grid computing middleware. It provides a common interface for transferring computing tasks to various distributed computing systems and can include grid infrastructures of varying size and complexity.
The dCache and EOS systems are used as the main data storage systems. The afs is used for user home directories, cvmfs storage systems is used to store project software (cvmfs is a system for distributed access and organization of software versions for collaborations and user groups, cvmfs is used to store project software).
Tier1 farm configuration (T1_RU_JINR):
The CMS experiment data processing jobs are launched by 16 core pilots and all computing resources are available to them.
Computing farm (CE)
2025Q3:
23360 cores; perfomance 427920.04 HEP-SPEC06; Average HEP-SPEC06 per Core = 18.32; CMS can take up all cores, NICA up to 4000 cores.
2025Q2:
Support for the RHEL7 OS distribution and clones — SL7, SLC7, Centos7 has ended. On most CICC computers (Tier 2, Tier 1) we are switching to the OS Alma Linux 9 . (This OS is almost a complete clone of RHEL9.)
2025Q1:
