Add note to slurm.conf man page about setting "--cpu_bind=no" as part
of SallocDefaultCommand if a TaskPlugin is in use.

Revert call to getaddrinfo, restoring gethostbyaddr (introduced in Slurm
    16.05.0pre1) which was failing on some systems. Specifically test7.2
    was failing on some systems with getaddrinfo() returning an error of
    "System error: Resource temporarily unavailable". Partial reversion
    of commit 89621f65

was also given.

Split partition's "Priority" field into "PriorityTier" (used to order
    partitions for scheduling and preemption) plus "PriorityJobFactor" (used by
    priority/multifactor plugin in calculating job priority, which is used to
    order jobs within a partition for scheduling).

a partition.

This also reverts most of commit fa331e30 as well as commit bd9fa830
which would try to set the pn_min_cpus every time a job was updated.
If a job didn't request node counts then they were hosed.

This commit takes away the magic which was screwing things up.  Now the
person gets what they asked for without magic changing things.

erroneously.

This whole process could probably be done better by keeping track of
old values and new values and only calling one function instead of a
pre and post function, but that can probably wait for future generations
of the code as it works now and is probably adequate for the time being.

Match acct_gather_energy/rapl plugin. Bug 2397.

Control whether the scheduler will continue to try to run jobs in
a partition if a higher priority job is stuck due to an association
limit.

Can cause starvation for larger jobs, but will improve throughput and
utilization for systems that have extensively divvyed up their resources
through association/QOS limits.

have been selected set the time limit appropriately if the job didn't
request one.

If the partition has no DefaultTime setting, and no time_limit was given
for the job, job_ptr->time_limit == NO_VAL.

With AccountingStorageEnforce=safe this will prevent jobs from ever
starting if the association has any limit set for CPUMins.
(NO_VAL * cpus is a very large number, but if no time_limit is given
anywhere that is what they get :))

commit.

Calling _init() on the plugins can have side-effects, and is not safe.

E.g., select/bluegene, switch/nrt, */cray, all make calls to
external APIs that could cause unexpected problems.

This reverts commit 19fc9d94.

Compare the saved clustername to slurmctld's, if there's a mismatch prevent

Reproduced with:

Add new PowerParameters options of get_timeout and set_timeout. The default

This is being reverted because we have been informed turning off NHC by
default is not what Cray wants.  We hope for a day when this will be
the case and Slurm can run NHC on the compute node but until that day
this is the way we will handle it.
