When determining when a pending job will be able to start, rather than testing after removing each running job and trying to schedule the pending jobs, remove multiple jobs that all end about the same time before testing. This reduces the number of calls to the job placement logic, which is time consuming.

constraints mattered in a job. Details include: A job doesn't request memory but the system is running with CR_*MEMORY with no default memory limit and the job requests nodes with features of different sizes. Previously the order of constraints mattered where the smaller memory node would need to be requested first or the job would fail. Bug 2608

Previous logic would get an account and/or QOS time limit and use that value to overwrite the incoming RPC's NO_VAL value, which would change a job's time limit when changing an unrelated field (e.g. priority, QOS, etc.). bug 2610

Fix backfill scheduler race condition that could cause invalid pointer in select/cons_res plugin. Bug introduced in 15.08.9, commit: efd9d35e The scenario is as follows 1. Backfill scheduler is running, then releases locks 2. Main scheduling loop starts a job "A" 3. Backfill scheduler resumes, finds job "A" in its queue and resets it's partition pointer. 4. Job "A" completes and tries to remove resource allocation record from select/cons_res data structure, but fails to find it because it is looking in the table for the wrong partition. 5. Job "A" record gets purged from slurmctld 6. Select/cons_res plugin attempts to operate on resource allocation data structure, finds pointer into the now purged data structure of job "A" and aborts or gets SEGV Bug 2603

Rename partition configuration from "Shared" to "OverSubscribe". Rename salloc, sbatch, srun option from "--shared" to "--oversubscribe". The old options will continue to function. Output field names also changed in scontrol, sinfo, squeue, and sview.

Update a node's socket and cores per socket counts as needed after a node boot to reflect configuration changes which can occur on KNL processors. Note that the node's total core count must not change, only the distribution of cores across varying socket counts (KNL NUMA nodes treated as sockets by Slurm).

Remove the SchedulerParameters option of "assoc_limit_continue", making it the default value. Add option of "assoc_limit_stop". If "assoc_limit_stop" is set and a job cannot start due to association limits, then do not attempt to initiate any lower priority jobs in that partition. Setting this can decrease system throughput and utlization, but avoid potentially starving larger jobs by preventing them from launching indefinitely.

There was a subtle bug in how tasks were bound to CPUs which could result in an "infinite loop" error. The problem was various socket/core/threasd calculations were based upon the resources allocated to a step rather than all resources on the node and rounding errors could occur. Consider for example a node with 2 sockets, 6 cores per socket and 2 threads per core. On the idle node, a job requesting 14 CPUs is submitted. That job would be allocted 4 cores on the first socket and 3 cores on the second socket. The old logic would get the number of sockets for the job at 2 and the number of cores at 7, then calculate the number of cores per socket at 7/2 or 3 (rounding down to an integer). The logic layouting out tasks would bind the first 3 cores on each socket to the job then not find any remaining cores, report the "infinite loop" error to the user, and run the job without one of the expected cores. The problem gets even worse when there are some allocated cores on a node. In a more extreme case, a job might be allocated 6 cores on one socket and 1 core on a second socket. In that case, 3 of that job's cores would be unused. bug 2502

This is a revision to commit 1ed38f26 The root problem is that a pthread is passed an argument which is a pointer to a variable on the stack. If that variable is over-written, the signal number recieved will be garbage, and that bad signal number will be interpretted by srun to possible abort the request.
