• interactive cluster (five 64-bit machines)

• computing farm:

Currently, the 2019 farm the data processing system at the JINR CMS Tier1 consists of :

415 64-bit machines (WNs): 2 x CPU, 6-16 core/CPU (Typically SuperMicro Blade), that forms altogether

Total: 9200 core for batch processing and provides

Total performance : 132813 HEP-kSI2k

• cvmfs

The CVMFS is used to deploy large software packages of collaborations working in the WLCG.

• Software:

The Torque 4.2.10/Maui 3.3.2 software (custom build) is used as a resource manager and task scheduler.

The PhEDEx software is used as a tool for management of CMS data placement.

The standard WLCG program stack is used for data processing.

FTS - File Transfer System is used for data transfer .
