JSS

• Started implementing the process for parsing the
  job log file
• Cancelling the job if failures gt RetryCount
• Mail to UserContact when job starts running
• Notifying the RB (JOB_DONE, JOB_CANCELLED,
  JOB_ABORTED)
• Notifying the LB service (JSSTransferEvent,
  JSSJobDone, JSSJobAborted)

JSS

• Missing Condor-G functionalities hopefully
  delivered by the end of next week
• Info about failure of a submission to a Globus
  resource missing in the job log file (only
  present in the gridmanager log file)
• Necessary if we want to exploit the
  libcondorapi.a to parse the log file
• Info about when a job has been successfully sent
  to a Globus resource missing
• Only the events submitted, running and
  completed are recorded
• Necessary to notify the LB service
• New gridmanager able to exploit the persistent
  jobmanager
• New reliable (two phase commit) submission
  protocol

Refresh of user proxy

• Agreed with Condor team on
• New command (e.g.
• condor_refresh_proxy ltcondor-job-idgt
  ltnew-proxy-filegt
• The problem of forwarding the new fresh proxy
  to the Globus jobmanager is addressed by killing
  the jobmanager and restarting a new one
• Not the ideal solution, but it should be
  easier/faster to implement than adding proxy
  refresh functionality to Globus
• Should be ready by mid of August

What is needed

• Assumption
• RB doesnt need user proxy at PM9
• CESNET variant 4 ?
• MyProxy server
• Running in the RB/JSS machine ?
• Long-term limited proxy moved from UI to RB/JSS
  machine
• Do we know how to generate long term limited
  proxy ?
• What should be changed in the UI ?
• JSS before submitting a job
• Retrieve full short time proxy from MyProxy
  server, using the long-term limited proxy
  (without using password)
• What is necessary to modify for not using
  password ? Who ?
• Polling by JSS, and for proxies that are being
  expired
• Retrieve full short time proxy from MyProxy
  server, using the long term limited proxy
  (without using password)
• Issue condor_refresh_proxy
