Computing resources for MPD data processing

CPU: 128 XEON cores GPU: ~1500 TESLA cores

Computing resources for MPD data processing

CPU: 128 XEON cores => in future ~10 000 XEON cores GPU: ~1500 TESLA cores

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!

Thank you for your attention!

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.
