Summary PHYSGI Meeting 5/9/94

                                                         B. Gibbard


    Next meeting will be Monday, May 16, 11:30 - 12:00, in the Orange Room.



    Groups who announced that they would be doing production processing during
    the week of May 2 are:

        1)  E891 (Saulys et al.) - ~2 CPU intensive Monte Carlo job.

        2)  E881 (Hackenburg et al.) - ~6 CPU intensive jobs.

        All experiments which anticipate running more than an single occasional
        production job during a given week are required to attend the
        scheduling meeting. If that is not possible they should notify Bruce
        Gibbard (gibbard@bnl.gov) and Tom Throwe (throwe@rsgi02.rhic.gov)
        of their needs by Email prior to the Monday 11:30 meeting.


    Plan for week beginning 5/9/94:

        The rules will be the same as for last week:

        A production job is defined as any job which will accrue an hour or
        more of CPU time.
        
        Each experiment is still allowed to run up to 6 concurrent "production"
        jobs but all except 1 of those six must be run "niced" to "1".


    Other issues:

        No recurrence of the strange behavior of "un-niced" jobs getting
        smaller shares of CPU than "niced" jobs were reported for last week.
        However E881 is still concerned about this problem and is suggesting a
        stronger "nice" level, perhaps 4.  They will reproduce their experiment
        which showed strange behavior and the issue will be discussed again next
        week.

        All of the protective delays have now been removed from Bob Hackenburg's
        jobs but the PHYSGI01 hangs of a month ago have not recurred.  It is
        not considered fully proven but this is at least suggestive of the
        possibility that the problem may be gone.

        Users of PHYSGI01 are still strongly encourage to set a mail forward
        from their working account on PHYSGI01 to an account on a machine where
        they frequently check their mail so that they can be easily contacted.
