2 User Interface (UI) E’ la macchina con i comandi per la sottomissione a Grid voms-proxy-init / grid-proxy-init edg-job-sumit edg-job-status 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)

6 Worker Nodes (WN) grid009.mi.infn.it grid012.mi.infn.it grid016.mi.infn.it grid017.mi.infn.it grid018.mi.infn.it grid019.mi.infn.it grid021.mi.infn.it grid022.mi.infn.it grid023.mi.infn.it grid024.mi.infn.it grid025.mi.infn.it grid026.mi.infn.it t2-wn-02.mi.infn.it t2-wn-03.mi.infn.it t2-wn-04.mi.infn.it t2-wn-05.mi.infn.it

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

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

22 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.multicast It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization.
