  1. Introduction environment, scripts, visualization, …

  2. Overview • computer characteristics • scripts and environment • how to submit a job • visualization • frodo, edf, chagal, viewer

  3. Computer characteristics

  5. Submit a job Loadleveler • commands: • llsubmit: submit a job • llq, (upr): check running jobs • llcancel: cancel a job • classes: big(8), medium(4), mono(1) • submit syntax: value=val llsubmitscript • job header: #@ ll_command = value

  6. test.sh #!/bin/ksh #@ job_name = test #@ job_type = parallel #@ environment = COPY_ALL #@ output = out.$(job_name).$(jobid) #@ error = err.$(job_name).$(jobid) #@ notification = never #@ total_tasks = 4 #@ class = medium #@ arguments = ${ARG} #@ queue set –x echo ARG=${ARG} sleep 20 exit 0

  7. submit the job: $ ARG=3 llsubmit test.sh llsubmit: The job “regatta.met.hu.79174” has been submitted. check running jobs: $ llq Id Owner Submitted ST PRI Class Running On --------------- ------- ---------- -- --- ------ ----------- regatta.79174.0 wshop016/1 07:32R 50 medium regatta regatta.79166.0 szepszo6/1 06:36R 50 big regatta cancel a job: $ llcancel 79174 llcancel: Cancel command has been sent to the central manager.

  8. Visualization and related tools • frodo: view file header and list of fields • edf: dump a selected field to ascii • chagal: visualize a field • Viewer: check ODB content
