Computing Service

2019:

JINR Tier1 computing service is presented:

• interactive cluster (five 64-bit machines)

and

• 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:

* OS: Scientific Linux release 6 x86_64.
* GCC: gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3)
* C++: g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3)

* BATCH : Torque 4.2.10 (home made)
* Maui 3.3.2 (home made)
* CMS Phedex
* dCache-3.2
* Enstore 4.2.2 for tape robot.

* WLCG (2xCREAM, 4xARGUS, BDII top, BDII site, APEL parsers, APEL publisher,

EMI-UI, 220xEMI-WN + gLExec-wn, 4xFTS3, LFC, WMS, L&B, glite-proxyrenewal)

* cvmfs

* FTS

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 .
