Summary PHYSGI Meeting 4/25/94

                                                         B. Gibbard


    Next meeting will be Monday, May 2, 11:30 - 12:00, in Room 2-160.



    Major users for the week beginning 4/25/94 are expected to be:

        1)  E871 (Worm et al.) - 3 CPU intensive Monte Carlo jobs

        2)  E881 (Hackenberg et al.) - 6 CPU intensive data analysis jobs 

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

        4)  E850 (Gushue et al.) - 4 CPU intensive analysis jobs by Zack

        5)  E818 (Weygand et al.) - possible occasional multiple CPU intensive
                                    jobs.

    Plan for week beginning 4/18/94:

        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 allowed to run up to 6 concurrent "production"
        jobs but all except 1 of those six must be run "niced" to "1".


    Status of problems from the Upgrade to IRIX 5.2:

        CASEVISION debugger is now working.

        Clock irregularity problem has been worked around.

        EScall is broken under IRIX 5.2 and SGI is on notice.

        FORTRAN bug is now fixed.

        Tapeman has been fixed and now works as it did under IRIX 4.05

    Other issues:

        Users of PHYSGI01 are 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.

        Some strange behavior has been observed with "nice".  Sometimes a
        non-niced job falls to a very low share after other jobs are "niced"
        by 1.   This was not observed to occur consistently and was not
        understood, however, the general trend of the system performance under
        the new rules seemed positive so we will continue to use them and see if
        some understanding of this strange behavior can be reached.
