• Previous meetings, MeetingMinutes

Scalability testing

• Suchandra's local invocations tests
  • earlier tests didn't have maxThreads reset to higher value. Did that (set to 200) and
    • container no longer crashes at 1Hz submission rate
    • local invocation now gives superior response
  • put in request to vdt-support to have increased maxthreads level set by default.
• Jeff's client timeout tests
  • globusrun-ws option '-T #' did not seem to work or I set it too low (~10 minutes)
  • adding containerTimeout parameter in server-config.wsdd file and setting to 1000000 (~16 minutes) did work
    • 370 out of 375 jobs went through successfully
    • 5 jobs failed with

       ....
      Current job state: StageOut
      Current job state: Failed
      Destroying job...Done.
      Cleaning up any delegated credentials...Done.
      globusrun-ws: Job failed: Staging error for RSL element fileStageOut.
      Message expired (outside window)
      

• Charles says these results point to the server container (not the client-container) as having the timeout. And small number of failures may be a security catch all whereby any message carries a time-limit.
• Terrence's Condor-g testing at UCSD
  • just now was able to push the service into operation by running the seg by hand.
  • still an open question why this doesn't work when container is started initially
  • will start running tests with Condor-g

OSG Integration activities (Charles)

• How to address 3 issues (interop, accounting, log-rotation)
  • reporting: Stu notes that supporting log-rotation in Condor is underway or persons identified
  • accounting: there are outstanding bug reports from John Wiegand that spell out the issues ... followup from there
  • interop: Charles needs to re-ignite email thread based on CE element from GlueSchema? 1.3
• Involvement of Big VOs
  • CMS involvement will follow Terrence's tests
  • Atlas contact made

To Do List

• submit bug report for maxAttempts not working (Jeff)
• Suchandra will be running through Condor-g tests Types I - VII
• Charles to follow up on accounting & reporting
• Jeff will be finishing SGE log-rotation and following up on SGE/Globus interations
• All will have fun over the holidays
