This commit adds a new field free_mem to the node_info struct
and augments the 15.08 RPC protocol to exchange this information
as part of the ping and registration status messages. The
free memory is taken from the sysinfo() information on systems
that support this function. Overall, the implementation sticks
to the way cpu_load (the 5 min load average) is handled.

Bug 1819

Composite indexes search left to right. E.g. an index of (inx1, inx2, inx3) will search from left to right. inx2 can't be used in a where statement by itself, it requires inx1 to be present (inx3 can be optional). For the rollup index having time_end first speeds up the below query. The actual rollup queries still benefit from the original rollup index.

If node definitions in slurm.conf are spread across multiple lines
and topology/tree is configured, then sub-optimal node selection can
occur.
bug 1645

On Cray we were seeing an srun error reading slurmstepd message header.
  This was due to a shutdown race condition and the error message has
  been removed.

bug 1786

Previously only batch job completions were being captured.
bug 1820

If a job was running on the node when slurmctld restarted. The slurmd
would notify slurmctld when the job ended and slurmctld would change
its state from UNKNOWN to IDLE, at least if the job termination happened
prior to the slurmd being asked for configuration information. The
configuration information might then not be collected for some time.
I've modified the code to address this problem and try to collect
configuration information from every node after slurmctld startup,
eliminating this race condition.

Bug 1208

This patch provides a rewrite of how /proc/cpuinfo is parsed in common_jag.c, as the original code made the incorrect assumption that cpuinfo follows a sane format across architectures ;-)

The motivation for this patch is that the original code was producing stack smashing on a POWER7 running RHEL6.4 Red Hat adds -fstack-protector along with a lot of other protective CFLAGS when building RPMs. The code ran okay with -fno-stack-protector, but that is not the best work-around.

So, the relevant /proc/cpuinfo line on an Intel (Xeon X5675) system looks like:

cpu MHz                : 3066.915

Whereas the relevant line in a POWER7 system is

clock                : 3550.000000MHz

My patch replaces the assumption that the relevant number starts 11 characters into the string with another assumption: That the relevant number starts two characters after a colon in a string that matches (M|G)Hz.

All in all, the function has a few more calls, which may be a performance issue if it has to be called multiple times, but since the section I edited only gets evaluated if we don't know the cpu frequency, getting it right will actually result in fewer string operations and unnecessary opens of /proc/cpuinfo for systems likewise affected.

Finally, I also read the actual value into a double and multiply it up to the size indicated by the suffix, so we end up with KHz? It was unclear what the original code intended, since it matched both MHz and GHz, replaced the decimal point with a zero, and read the result as an int.

This reverts commit 2c95e2d2.

Conflicts:
	src/plugins/select/alps/basil_interface.c

This is related to bug 1822.  It isn't clear why the code was taken out in
this commit in the first place and based off of commit 2e2de6a4 (which is
the reason for the conflict) we tried unsuccessfully to put it back.

It appears the only difference here is the addition of
always setting mppnppn = 1 instead of always to
job_ptr->details->ntasks_per_node when no ntasks is set.

This appears to only be an issue with salloc or sbatch as ntasks
is always set for srun.

Bug 1783

Prevent slurmctld abort on update of advanced reservation that contains no
    nodes.
bug 1814

srun command line of either --mem or --mem-per-cpu will override both the
SLURM_MEM_PER_CPU and SLURM_MEM_PER_NODE environment variables.
Without this change, salloc or sbatch setting --mem-per-cpu (or a
configuration of DefMemPerCPU) would over-ride the step's --mem
value.

Previous logic could fail to update some tasks of a job array for
  some fields.
bug 1777

bind to the interface of return of gethostname instead of any address on
the node which avoid RSIP issues in Cray systems.  This is most likely
useful in other systems as well.

Fix to job array update logic that can result in a task ID of 4294967294.
To reproduce:
$ sbatch --exclusive -a 1,3,5 tmp
Submitted batch job 11825
$ scontrol update jobid=11825_[3,4,5] timelimit=3
$ squeue

A new job array entry was created for task ID 4 and the "master" job

Bug 1799

Increase total backfill scheduler run time in stats_info_response_msg data
    structure from 32 to 64 bits in order to prevent overflow.

remove new capabilities added in comit ad9c2413
Leave the new logic only in version 15.08, which has related
performance improvements in the slurmctld agent code, see commit
53534f49

Modify slurmctld outgoing RPC logic to support more parallel tasks (up to
    85 RPCs and 256 pthreads; the old logic supported up to 21 RPCs and 256
    threads). This change can dramatically improve performance for RPCs
    operating on small node counts.
bug 1786

Correct "sdiag" backfill cycle time calculation if it yields locks. A
    microsecond value was being treated as a second value resulting in an
    overflow in the calcuation.
bug 1788

The slurmctld logic throttles some RPCs so that only one of them
can execute at a time in order to reduce contention for the job,
partition and node locks (only one of the effected RPCs can execute
at any time anyway and this lets other RPC types run). While an
RPC is stuck in the throttle function, do not count that thread
against the slurmctld thread limit.
