Add Slurm overview by Alex on first day, move KNL to second morning,
shift roadmap to right after lunch.

Previous cap was 2 sec (default TCP timeout) times the node count
  and divided by 1000. A 9000 node job would have the messages
  spread out over 18 seconds. This change caps the spread at
  5 seconds and assumes the normal TCP logic can handle the rest
bug 3044

If the overhead of determining the hostlist for a given task list
is too high, then report a hostlist of "Unknown" instead. If the
overhead is too high, then srun will become unresponsive and communications
will timeout/fail.
bug 3044

Modify srun task completion handling to only build the task/node string for
    logging purposes if it is needed. Modified for performance purposes.
bug 3044

Add get_log_level() function to return the highest LOG_LEVEL_* used
for any logging mechanism.

This reverts commit 1ec2a4ae.

Bug 3063.

Restructure srun command locking for task_exit processing logic for improved
  parallelism. This change decreases the amount of time consumed by serial
  logic by 2 orders of magnitude.
bug 3044

Preserve node "RESERVATION" state when one of multiple overlapping
    reservations ends. Previous logic would clear the node's
    RESERVATION state flag when any one of the reservations on the
    node ended rather than keeping the node in RESERVATION state
    until the last reservation ended.
bug 3057

The logic is now heavier weight, so increase interval between tests
  from 2 to 5 seconds

Handle case when slurmctld daemon restart while compute node reboot in
    progress. Return node to service rather than setting DOWN.
bug 3042

Add salloc_wait_nodes option to the SchedulerParameters parameter in the
    slurm.conf file controlling when the salloc command returns in relation to
    when nodes are ready for use (i.e. booted).

sched/backfill - Check that a user's QOS is allowed to use a partition
    before trying to schedule resources on that partition for the job.

Otherwise blade_cnt is potentially greater than
bit_size(jobinfo->blade_map) which leads to an assertion failure.

instead of 2+. Continuation of previous commit.

with hwloc.

This patch has two parts:
1. When a job is intially submitted, the Slurm was failing to set
   an initial reason for the job not starting.
2. After a job was submitted, it was sometimes failing to reset
   the job's reason. It was also failing to reset the "last_job_update"
   time, so something like "squeue -i1" would not get the new reason.

Fix multipart srun submission with EnforcePartLimits=NO and job violating
    the partition limits.
