---++ Agenda

Status
   * CSCS: 
      * Implemented punish system for find/du/ls. Job gets 30 seconds sleep after more than 10 bad ops / minute.
   * PSI (reports Fabio): 
      * PSI hosted the HPC Forum on Scheduling and Queue System, in that context we presented our [[%ATTACHURL%/FabioMartinelli-SGE_ARCo.pdf][Sun Grid Engine Accounting and Reporting Console]].
   * UNIBE (reports Gianfranco): 
      * Experiencing random spontaneous reboots of X8440 blades. One module refuses to power back up. Network upgrade still pending (tentatively next Wednesday)
   * UNIGE (reports Szymon): 
      * In general rather quiet (I can do other things)
      * Occasional slow response of NFS, under investigation since early march: 
         * It is not as simple as overloaded file servers.
         * Slow response happens on one client at a time, not on all the same time.
         * Have a look at slides attached: [[%ATTACHURL%/UniGE.NFS-monitoring-results.pdf][UniGE.NFS-monitoring-results.pdf]].
         * It would be good to understand what is the limit. Thanks in advance for any ideas of things to check etc.
Other topics
   * Change of CSCS Maintenance day: "First working Wednesday of the month". Next one: Wednesday 8th of June.
   * Agreed to talk about technical things (like Szymon's) on the lcg at cscs list
