Slurm built with ALLOCATE_FULL_SOCKET = 1

Node n8 has the following layout:
Socket 0: CPUs 0-3
Socket 1: CPUs 4-7

Without fix to _allocate_sockets (incorrect allocation for -c values of 3, 5, 6, and 7):

Patch by Bill Brophy, Bull.

You'll find this as commit 2079c03f58 to the chaos/slurm 2.3.3.chaos branch on March 7.  This is against SchedMD's master branch:

Patch by Don Lipari, LLNL.
https://github.com/chaos/slurm/commit/4de11bf0a8cd18207a60e7d3e1fa7a6fde0da431

Move a log message before fork() call in the new spank prolog/epilog
logic. The original code could deadlock in glibc when getting the time
to include in the message.

If the select plugin does not allocate memory to a job, then do not
try to alloocate memory to the job step, without this the step allocation
will always fail

Fix bug in allocating GRES that are associated with specific CPUs. In some
cases the code allocated first available GRES to job instead of allocating
GRES accessible to the specific CPUs allocated to the job.
