[slurm-users] Weirdness with partitions

[Feng Zhang]

As I said I am not sure, but it depends on the algorithm and the code
structure of the slurm(no chance to dig into...). My imagination
is(for the way slurm works...):

Check limits on b1, ok,b2: ok: b3,ok; then b4, nook...(or any order by slurm)

If it works with the EnforcePartLimits=ANY or NO,  yeah it's a surprise...

(This use case might not be included in the original design of slurm, I guess)

"NOTE: The partition limits being considered are its configured
MaxMemPerCPU, MaxMemPerNode, MinNodes, MaxNodes, MaxTime, AllocNodes,
AllowAccounts, AllowGroups, AllowQOS, and QOS usage threshold."

Best,

Feng

The slurm.conf web page doesn't indicate that it affects the actual queuing decision, just whether or not a job that will never run (at all, or just on some of the listed partitions) can be submitted.  If it does help then I think that the slurm.conf description is misleading.
