As what we've talked about before in the telecon on 22 January, we need to have a new term to describe the free CPUs for the MPI job, FreeParallelCPUs perhaps?.
A comment on Stephen Burke's comment about GLUE 1.3 Issues/Comments #3: We don't think there's a way to calculate WorstResponseTime on a
How does this work? I would have assumed that if a system allows MPI it would allow it on any CPUs. Are you saying that if a system has, say, 16 free CPUs and will allow up to 12-processor MPI jobs it may still be the case that a 12-processor job won't run because only 10 of the free CPUs are free for parallel jobs? preemptive system. A worst response time for a job that user A submits now might not be valid anymore 5 minutes later because user B who has a higher priority submits a job and preempts the job submitted by user A. I still think this is a misunderstanding. Even on non-pre-emptive systems the values may be wrong in 5 minutes time because more jobs may be queued in that time and they may go in the queue in front of yours, the published values are only ever a current snapshot. (Conversely, jobs in front may be cancelled or executing jobs may abort so the times may also suddenly get shorter.) Stephen
