Jobs are not backfilled due to the fact that backfill does not finish the complete backlog of jobs in the queue before it's interrupted and starts all over again. We sometimes have lots of jobs in the queue of various sizes and users and even with idle nodes short job will not start because of this.  I have made a patch for backfill with a configuration option (bf_continue) to let backfill continue.

The original reservation data structure is deleted and it's backup
added to the reservation list, but jobs can retain a pointer to the
original (now invalid) reservation data structure.

energy data.

Without this fix, jobs that should be initiated by the backfill
scheduler based upon the preemption of other jobs will not be
started.

cnode does not have a job running on it do not resume the block.

Select/cons_res - If the job request specified --ntasks-per-socket and the
allocation using is cores, then pack the tasks onto the sockets up to the
specified value. Previously it would ignore the ntasks-per-socket
parameter and distribute tasks across sockets

--enable-debug.

Counts would previously go negative as jobs terminate and decrement from
a base value of zero

to EINTR when something wrong happened between the open call and
its return. By ensuring that Slurm retries on such errors, we can
better tolerate Network file systems errors at launch time.

Added Allocated Memory to node information displayed by sview and scontrol commands.

This makes the configuration parameter names consistent within
a partition and system-wide

Added new field to partition_info data structure
Break up some long lines and minor format changes
Move some definitions and statements into alphabetic order

1. Removed the job_submit and job_modify functions from the plugin, they are not required for the "slurmctld" plugin type
2. Renamed the new parameter from "JobSubmitDynAllocPort" to "DynAllocPort" and renamed the variable (You need to change this in your slurm.conf file)
3. Added logic so you can see the DynAllocPort value using "scontrol show config" or "sview"
4. I made some minor formatting changes, mostly for lines that were too long
5. Added #ifdef to the msg.h header file
6. Changed the #ifdef variables in the header files to start with "DYNALLOC_", perhaps not needed, but it should safer, especiallly with some common names like "INFO_H"
7. I re-wrote much of info.c. There was no need to get a copy of the node information and process the copy. We can just work directly with the data structures.

These provide support for MapReduce+

Old logic uses some vestigial power management logic that no longer
applies. It creates a job allocation, but the job step blocks
indefinitely.
