Problems with unix group within LBS (for distributed analysis)

Discussion in 'Cadence' started by Ulrich Seeling, Dec 6, 2004.

  1. Hi *,

    I made following experience when trying to use Sun Gridengine via LBS for
    distributed analysis:
    Even SGE is configured correctly so that it used the effective group id of
    the user submitting the job it seems that the LBS daemon does not transfer
    this information correct (IC5.0.33).
    So if user U with default group g1 switches to group g2 and executes spectre
    via LBS (which puts the job into sge), the result files have the ownership
    of U with group g1 instead of g2. That can cause problems in an environment
    where project access is done via unix group membership ...

    Can somebody confirm or negate this behaviour ?
    (Anybody using LBS and using unix group id switching ?)

    regards

    Ulrich

  2. A similar problem was reported recently by one of our large German
    customers - the issue is that cdsqmgr doesn't preserve the primary group
    in the submitted job.

    I suggest you contact customer support, and then we can tie you in with
    the PCR for this:

    PCR: 754666
    Title: cdsqmgr change unix group for users

    However, that was a question PCR - I'm not sure whether anything is
    actually being fixed (it may be). But the best thing is to contact
    customer support via your usual channel, and reference this.

    Andrew.

  3. Hi Andrew,

    thanks for your pointer to the PCR.
    I contacted customer support and there has been no progress in this issue.
    Unfortunaty on another PCR, which would make this one obsolete I hope, the
    full integration of SGE in distributed analysis, there has no progress too.
    These items are only P1...

    I estimate it to need another 6-12 months to have the SGE integration done.

    Thanks

    Ulrich
