Event Service on HPC

Defining a panda queue for the Event Service is similar to defining an MCORE queue. Here we will only specify differences.

  • catchall: localEsMerge,jobseed=es,HPC_HPC,mode=normal,queue=debug,repo=m2015
    • localEsMerge defines location of the merge job. If you don't want to merge at the same queue, remove it. * For preemptable queues, please remove it. The merge job should not be preempted. * For MCORE, please remove it. The merge job is a single core job.
    • jobseed=es is used by panda to schedule only ES jobs to this queue.
    • HPC_HPC is needed for pilot to start Yoda process.
    • mode=normal Yoda can run in 'normal' mode and 'backfill' mode.
    • queue=debug HPC job queue
    • partition=edison HPC partition
    • repo=m2015 HPC repo
    • For the other parameters, there are default value. If you want to override it, you can set it in catchall.
    • These are examples:
                  catchall: "HPC_HPC,log_to_objectstore,mode=normal,queue=regular,backfill_queue=regular,max_events=200000,initialtime_m=3,time_per_event_m=13,
                  catchall:  "HPC_HPC,mode=normal,queue=debug,backfill_queue=regular,max_events=2000,initialtime_m=8,time_per_event_m=13,repo=m2015,nodes=2,
                  catchall:  "HPC_HPC,mode=backfill,queue=debug,backfill_queue=regular,max_events=2000,initialtime_m=8, time_per_event_m=10,nodes=2,min_nodes=2,

  • corecount:
    • It's used by pilot to set ATHENA_PROC_NUMBER which defines to start multiple processes for AthenaMP. It can be 1.

  • objectstore:
    • It's used by pilot to send finished event objects to objectstore. The 'objectstore' item in schedconfig is not used anymore.
    • You need to click "Find and associate another ObjectStorage/Bucket. Modify attached objectstores" in AGIS "PandaQueueObject Info" page. Then fill "bnl_os" in the "Search OS buckets:" textbox and click "Search objectstores". Select all three buckets and save.
