  1. Tier2 di MilanoComponenti e Monitoring Luca Vaccarossa Milano 14 dicembre 2007

  2. User Interface (UI) • E’ la macchina con i comandi per la sottomissione a Grid • voms-proxy-init / grid-proxy-init • edg-job-sumit <file.jdl> • edg-job-status <jobid> • edg-job-get-output

  3. User Interface (UI) • atlfarm008.mi.infn.it • atlfarm010.mi.infn.it • grid008.mi.infn.it

  4. Computing Element • t2-ce-01.mi.infn.it • Grid gateway • PBS server (TORQUE) • MAUI scheduler

  5. Computing Element Il sistema batch della farm e' Torque + Maui. le code abilitate per gli utenti locali sono: • local (max cpu time 48h, max walltime 72h) • short (coda corta con cpu riservate, max cpu time 40m, max walltime 2h)

  8. Comandi PBS showq Show job status and some job info showbf [-v] Check for immediately available CPUs and nodes checkjob [-v] <job_id> | qstat -f <job_id> Check job status canceljob <job_id> Cancel a job, sending essentially a qdel to the pbs_server showstart [-h] <job_id> Show when job is scheduled to start

  9. Comandi PBS • PBSNODES –a | less • Si vedono i WN che non hanno job • Segnalare a grid-help@mi.infn.it

  16. GridView • http://gridview.cern.ch/GRIDVIEW/ • Monitoring and Visualization Tool for LCG • Data Transfer • Job Status   • Service Availability

  17. SAM Tests • https://lcg-sam.cern.ch:8443/sam/sam.py • Certificato nel browser • Test automatici • SAM on demand? • https://cic.gridops.org/index.php?section=rc&page=samadmin

  18. Ganglia • http://ganglia.sourceforge.net/ • “Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids.”

  19. Ganglia • It relies on a multicast-based listen/announce protocol to monitor state within clusters and uses a tree of point-to-point connections amongst representative cluster nodes to federate clusters and aggregate their state. • It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization.
