i.e. salloc -n32 doesn't request the number of nodes and with the previous code if this request used 4 nodes and only 1 was left in GrpNodes it would just run with no issue since we were checking things before we selected how many nodes it ran on. Now we check this afterwards so we always check the limits on how many nodes, cpus and how much memory is to be used.

Fix step allocation when some CPUs are not available due to memory limits. This happens when one step is active and using memory that blocks the scheduling of another step on a portion of the CPUs needed. The new step is now delayed rather than aborting with "Requested node configuration is not available". bug 577

data correctly accumulating differences between sampling intervals. Fix the data structure mismatch between acct_gather_filesystem_lustre.c and slurm_jobacct_gather.h which caused the hdf5 plugin to log incorrect data.

If a job is explicitly suspended, its priority is set to zero. This resets the priority when requeued and also documents that if the job is requeued (e.g. due to a node failure), then it is placed in a held state.

Without this patch, the job's RunTime includes its RunTime from before it's prior suspend (i.e. the job's full RunTime rather than just the RunTime of the requeued job).

Hello, I think I found another bug in the code (I'm using 2.6.3 but I checked the 2.6.5 and 14.03 versions and it's the same there). In file sched/backfill/backfill.c: 1) _add_reservation function, from lines 1172: if (placed == true) { j = node_space[j].next; if (j && (end_reserve < node_space[j].end_time)) { /* insert end entry record */ i = *node_space_recs; node_space[i].begin_time = end_reserve; node_space[i].end_time = node_space[j].end_time; node_space[j].end_time = end_reserve; node_space[i].avail_bitmap = bit_copy(node_space[j].avail_bitmap); node_space[i].next = node_space[j].next; node_space[j].next = i; (*node_space_recs)++; } break; } I draw a picture with `node_space` state after 2 iterations (see attachment). In case where the new reservation is fully inside another reservation, then everything is OK. But if the new reservation spans multiple existing reservations then the `end entry record` is not created. This is because only the newly created `start entry record` is checked. Easy fix would be to change the if into a loop, for example: if (placed == true) { while((j = node_space[j].next) > 0) { if (end_reserve < node_space[j].end_time) { //same as above break; } } break; } 2) You could also change line 612: node_space = xmalloc(sizeof(node_space_map_t) * (max_backfill_job_cnt + 3)); To `(max_backfill_job_cnt * 2 + 1)` , since each reservation can add at most two entries (check at line 982 should never execute). At the moment, in a worst case scenario this only checks half of the max_backfill_job_cnt. NOTE: However this is all based on the assumption, that it is not done on purpose to speed up the calculations and trading some of the accuracy (especially point 2). Best regards, Filip Skalski
