      avoid delay on commit for PMI task at rank 0 · fcc11e22
      Rémi Palancher authored
      Intel MPI, on MPI jobs initialisation through PMI, uses to call PMI_KVS_Put()
      many many times from task at rank 0, and each on these call is followed by
      PMI_KVS_Commit(). Slurm implementation of PMI_KVS_Commit() imposes a delay
      to avoid DDOS on original srun. This delay is proportional to the total number.
      It could be up to 3 secs for large jobs for ex. with 7168 tasks. Therefore,
      when Intel MPI calls PMI_KVS_Commit() 475 times (mesured on a test case) from
      task at rank 0, 28 minutes are spent in delay function.
      All other tasks in the job are waiting for a PMI_Barrier. Therefore, there is
      no risk for a DDOS from this single task 0. The patch alters the delaying time
      calculation to make sure task at rank 0 will does not be delayed. All other
      tasks are globally spreaded in the same time range as before.

      Prevent vestigial job array record · 42d75a09
      Morris Jette authored
      If a master job array record is complete, then consider all pending
      tasks as also complete. This problem happens when a master job array
      record is pending (has pending tasks) and is cancelled. The result
      previously was a job record not visible to squeue/scontrol, but occupying
      memory.
      The same type of problem happened with respect to a dependency on a job
      array which was cancelled.
