Document that node Weight takes precedence over load with LLN scheduling.
bug 3204

task/cray's _get_numa_nodes() function needs to run before task/cgroup
cleans up the cgroup hierarchies, otherwise ALPS memory compaction will
never run.

Also move task_p_add_pid() outside the #ifdef HAVE_NATIVE_CRAY
block so that the plugin will load (albeit without any functionality)
on non-Cray systems for testing purposes.

Revise documentation and provided slurm.conf templates as well.

Bug 3154.

There is a problem with gathering batch step statistics for jobs which are allocated on more than one node.

Sstat asks wrong node for batch step stats. It requests info from last node from hostlist while it should ask first host from hostlist (i.e. BatchHost), because only on the first node the batch step actually executes.

For example, when you have a job allocated on nodes n000[1-2] with BatchHost=p0001. You should be able to check its statistics by running sstat [ with -vv switch for more verbose output] (e.g. sstat -j 1234.batch -vv). Then you can see lines:

sstat: debug:  slurm_job_step_stat: getting pid information of job 1234.4294967294 on nodes n0002
sstat: debug:  job step 1234.4294967294 has already completed

The problem lays in sstat source code. For batch step a hostlist variable is taken from the hostlist_pop function, which returns last host from given hostlist. This should be replaced with the hostlist_shift function, which returns first host from the given hostlist. Patch attached.

This commit fixes a bug in the multi-prog handling. When running
salloc -N 2 srun -O --multi-prog mp.conf where mp.conf reads

0-192 true

srun crashes can be observed. valgrind reports:

_select_nodes_parts() was resetting state_reason to an admin hold
without regard to admin vs user hold state. state_reason is the only
place that user vs. admin is distinguished, so this prevented users
from releasing these jobs.

Bug introduced by commit fb46c84b in 16.05.5.

Bug 3197.

This is an addition to commit cb7ed937

bug 3191

Improve reported estimates of start and end times for pending jobs.
bug 3184

Cray: Prevent abort in backfill scheduling logic for requeued job that has
    been cancelled while NHC is running.
bug 3185

Modify DataWarb example to use an environment variable rather than absolute path

new glibc 2.24+ that depricates readdir_r.

This reverts commit 8bc8e7e6.

The slurm_strcasestr() which existed in v16.05 was removed in v17.02.

Fix for possibly treating a negative number as a positive.

Change the default syscfg path to /usr/bin/syscfg
Don't load the plugin if ResumeProgram is configured
Update documentation on web page

This applies only to knl_generic plugin. The original node active
features should be the same as the features field at startup.
The logic was assuming the original value was NULL.

This was a new function added to support knl_generic and it was
  originally assigned the wrong name.

Added node_features/knl_generic plugin for KNL support on non-Cray systems.
NOTE: This plugin is still under development.

Do not propagate SLURM_UMASK environment variable to batch script.
bug 2609

Correct a bitmap test function (used only by the select/bluegene plugin).
  The effect of this bug is probably very limited as it will in almost
  all cases revert prematurely to a bit-by-bit test rather than using
  a full-word test.
bug 3145

Cannot use ClusterName without reading a config file
that may not exist.

Bug 3026.

This introduced an inadvertent dependency on the config file,
which does not exist when setting up a new cluster.

Bug 3026.

This reverts commit c39f9ac9.

task/affinity plugin: Honor a job's --ntasks-per-socket and
    --ntasks-per-core options in task binding.
bug 3118

Changed in df70b651

Preserve non-KNL node features when updating the KNL node features for a
    multi-node job in which the non-KNL node features vary by node.

node_features/knl_cray plugin: If the reconfiguration of nodes for an
    interactive job fails, kill the job (it can't be requeued like a batch job).

Execute "capmc node_status" at more frequent intervals to handle
  nodes getting added or removed from the system using Cray tools
  (i.e. try to keep Slurm and Cray software better synchronized).

node_features/knl_cray plugin: Add separate thread to interact with capmc
    in response to unexpected node reboots.
