BLUEGENE - Modify "scontrol show step" to show I/O nodes (BGL and BGP) or c-nodes (BGQ) allocated to each step. Change field name from "Nodes=" to "BP_List=".

Previous code would fail when trying to launch more than 4096 tasks, which is a problem on BGQ systems where SLURM actually launches job steps.

This change applies only to Cray systems and only when the srun wrapper for aprun. Map --exclusive to -F exclusive and --share to -F share. Note this does not consider the partition's Shared configuration, so it is an imperfect mapping of options.

A node DOWN to ALPS will be marked DOWN to SLURM only after reaching SlurmdTimeout. In the interim, the node state will be NO_RESPOND. This change makes behavior makes SLURM handling of the node DOWN state more consistent with ALPS. This change effects only Cray systems.

Require SchedulerTimeSlice configuration parameter to be at least 5 seconds to avoid thrashing slurmd daemon. Addresses Cray bug 774692

Change in GRES behavior for job steps: A job step's default generic resource allocation will be set to that of the job. If a job step's --gres value is set to "none" then none of the generic resources which have been allocated to the job will be allocated to the job step. Add srun environment value of SLURM_STEP_GRES to set default --gres value for a job step.

Add the ability for a user to limit the number of leaf switches in a job's allocation using the --switch option of salloc, sbatch and srun. There is also a new SchedulerParameters value of max_switch_wait, which a SLURM administrator can used to set a maximum job delay and prevent a user job from blocking lower priority jobs for too long. Based on work by Rod Schultz, Bull.

Restore node configuration information (CPUs, memory, etc.) for powered down when slurmctld daemon restarts rather than waiting for the node to be restored to service and getting the information from the node (NOTE: Only relevent if FastSchedule=0).

Fix bug in select/cons_res task distribution logic when tasks-per-node=0. Eliminates misleading slurmctld message "error: cons_res: _compute_c_b_task_dist oversubscribe." This problem was introduced in SLURM version 2.2.5 in order to fix a task distribution problem when cpus_per_task=0. Patch from Rod Schultz, Bull.

Set SLURM_MEM_PER_CPU or SLURM_MEM_PER_NODE environment variables for both interactive (salloc) and batch jobs if the job has a memory limit. For Cray systems also set CRAY_AUTO_APRUN_OPTIONS environment variable with the memory limit.

For front-end configurations (Cray and IBM BlueGene), bind each batch job to a unique CPU to limit the damage which a single job can cause. Previously any single job could use all CPUs causing problems for other jobs or system daemons. This addresses a problem reported by Steve Trofinoff, CSCS.

If a job needed to preempt other jobs to start and those jobs were not completed by the time of the next scheduling cycle, other jobs might be selected for preemption in that next cycle resulting in more jobs being preempted than necessary.
