Presentation Transcript

  1. Remote operational center for CMS in JINR • Golunov, • XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011 A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  2. About JINR ROC The dedicated regional centre of remote monitoring and data analysis (CMS Regional Operation Centre) was founded in JINR in 2009. The main goal of this centre is operative and efficient monitoring of the detector systems. The centre is a part of the GRID technology–based Tier-2 sites which is focused to offline data processing and analysis. A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  3. JINR ROC functions • On-line monitoring of LHC Status • On-line monitoring of CMS detector systems including detectors of full JINR responsibility - Endcap Hadron Calorimeter (HE) and Forward Muon Stations (ME1/1) • data acquisitionand slow control • On-line monitoring of data taking • condition of the trigger system • data quality • Data Express Analysis • Remote CMS shifts and communications between JINR experts and shifters • Training, Information, Outreach A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  4. JINR ROC structure A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  5. Communication Links • To access for CMS monitoring services at LHC and CMS Control Room (SX5) and CMS Meyrin Centre (CERN) different communication ways are in use • Web-based monitoring points to a fixed mainly secured URL • LHC Monitoring Page 1 • CMS DAQ • CMS Global On-line and Off-line DQM GUI • CMS Detector Condition Page including trigger rate, run summary, magnet history etc • Secure shell (SSH) tunnels to access XDAQ executive processes that run in a private CMS network at SX5 • CMS TV Page for public overview of LHC and CMS Status, Live Event Displays, etc. A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  6. Remote shifts • From 2011 all subdetector shifts moved to ROCs: • Dubna • FNAL offline mode • MSU • Task of the shifters: • Offline DQM, Run registry, Run certification, e-log • Online DQM, alarm checking, slow control • Shifts covers ~6h in daylight (local time) A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  7. JINR participation in remote shifts • Since 2011 JINR ROC takes part in remote shifts for CMS. A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  8. Examples of Displays CMS DAQ Status LHC Beams Status Run Registry CMS Event Display A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  9. Examples of Displays (HCAL) A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  10. GRID access and data transfer JINR remote operational center (ROC) is an integral part of regional center JINR Tier-2 The experimental data are transfered from CERN (Tier-0/RDMS Tier-1)as well as from another CMS Tier-1 centers • PHEDEX system via global GRID infrastructure CMS for bulk transfer to JINR Tier-2 • data transfer from Tier-2 to JINR ROC via sftp • FileMover - individual file transfer to JINR ROC • User transfers via GRID/sftp to JINR Tier-2 and JINR ROC All data are processed at JINR Tier-2 and analyzed at JINR ROC within a few days A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  11. Local monitoring of system resources To prevent overheating and overloading of the server local monitoring was organized. It shows current core temperatures, disk and memory usage, user processes and so on. A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  12. Video conferencing • ROC video conferencing functions used for: • Communications between shifters • Local team meetings • Participating in remote seminars The equipment used for the communications is Tandberg MXP550. A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011

  13. Summary • JINR ROC was founded • The first year of operations OK • Meets all requirements • Since 2010 the centre is involved in CMS operations and remote shifts: • Dubna ROC is participating in the remote shifts • Future plans: • More CPU power for express analysis • More disk space for temporary data storage • Upgrade local monitoring system A.Golunov, “Remote operational center for CMS in JINR ”, XXIII International Symposium on Nuclear Electronics and Computing, BULGARIA, VARNA, 12-19 September, 2011
