Add description of SLURM_TOPOLOGY_ADDR and SLURM_TOPOLOGY_ADDR_PATTERN
environment variables to the topology web page.

Do not reset a job's priority when the slurmctld restarts if previously
set to some specific value.

This reverts commit 3464295e.

Do not mark the node DOWN if its memory or tmp disk space is lower
than configured, just log it using debug message type

The previous changes in commit bc3d8828
failed to address some accounting issues addressed here.

If a job is explicitly suspended, its priority is set to zero.
This resets the priority when requeued and also documents that
if the job is requeued (e.g. due to a node failure), then it
is placed in a held state.

Without this patch, the job's RunTime includes its RunTime from
before it's prior suspend (i.e. the job's full RunTime rather than
just the RunTime of the requeued job).

Hello,

I think I found another bug in the code (I'm using 2.6.3 but I checked the 2.6.5 and 14.03 versions and it's the same there).

In file sched/backfill/backfill.c:

1)
_add_reservation function, from lines 1172:

if (placed == true) {
        j = node_space[j].next;
        if (j && (end_reserve < node_space[j].end_time)) {
                /* insert end entry record */
                i = *node_space_recs;
                node_space[i].begin_time = end_reserve;
                node_space[i].end_time = node_space[j].end_time;
                node_space[j].end_time = end_reserve;
                node_space[i].avail_bitmap =
                        bit_copy(node_space[j].avail_bitmap);
                node_space[i].next = node_space[j].next;
                node_space[j].next = i;
                (*node_space_recs)++;
        }
        break;
}
I draw a picture with `node_space` state after 2 iterations (see attachment).

In case where the new reservation i...

midplane block that starts on a higher coordinate than it ends (i.e if a
block has midplanes [0010,0013] 0013 is the start even though it is
listed second in the hostlist).

It has been changed to improve the calculated value for pending
jobs and use the actual node count value for jobs that have been
started (including suspended, completed, etc.)
