Virtuoso creating 'ghost' jobs on LBS

jehh

Hello,

We experience that sometimes Virtuoso will start submitting 'ghost' jobs to the grid, effectively starting a simulation (spectre) job, but without the actual simulation to run.

Even when this jobs is killed, either from Virtuoso or externally from the LBS, it will resubmit this job. The LBS can kill the job, if the user have system admin permissions and specifies a forced closure (qdel -f <job-id>).

We have tried limiting the number of re-submits, to no avail.

Is there some settings that can trigger this constant re-submit? Can we limit the way Virtuoso can launch a job? Or other ressourcefull ways of limiting this behaviour?

Thanks in advance,

Christian

  • Christian,

    Something sounds odd here. There is the:

    adexl.distribute  numRetriesOnError int 1

    cdsenv setting (the default is the ADE XL/Explorer/Assembler will retry a simulation once if there's an error), but it doesn't sound as if that's quite the symptom you're seeing.

    I would suggest that you contact customer support - perhaps putting me or Janko on copy when you do that so that one of us can take the case? (I'm out for a few days, so I would probably redirect it to one of the others in the team this week).
