1. Development of the distributed monitoring system for the NICA cluster Ivan Slepov (LHEP, JINR) Mathematical Modeling and Computational Physics Dubna, Russia, July 8, 2013

4. The MultiPurpose Detector – MPD to study Heavy Ion Collisions at NICA

9. Computing resources for MPD data processing CPU: 128 XEON cores GPU: ~1500 TESLA cores

10. Computing resources for MPD data processing CPU: 128 XEON cores => in future ~10 000 XEON cores GPU: ~1500 TESLA cores

11. Motivation to develop monitoring system -Computing resources information (free space, memory, cpu, etc) -System load (load average, processes) -MPD software information (FairSoft version) -Cluster software information (SGE, xrootd, proof) -User tasks monitoring (batch processing and interactive jobs) MPD users need more information about all own cluster nodes and public computers!

14. Web- interface for Monitoring system 1.MPD software information 2.Computing resources information 3.System load 4.User tasks monitoring

15. Monitoring system web-interface User tasks

16. Monitoring system web-interface Interactive nodes

17. Access to the monitoring system on website mpd.jinr.ru

18. Thank you for your attention!

19. MPD users need more information about all own cluster nodes and public computers! Why? If, for example, the concept of grid uses a layer of abstraction from the resources. Because MPD software now still under development and needs testing and debugging. Motivation to develop system monitoring
