[slurm-dev] totalCpuAllocateTime or totalNodeTime etc.

[Sefa Arslan]

Hi ,

I cant find a proper name for the thing I described below. maybe 
overAllocatetime??

we have compute nodes with 16cores and 256 GB memory.  By default user 
can use 16GB memory per core max...  But when he/she send the job via 
--mem parameter, practically more memory than 16GB can be used per core. 
it is fine, some jobs need more memory...

for example a job sent  to queue with  N1 n1 --mem=256GB, the 
cpurawtime, cputime is calculated  for only one core (by squeue or 
sacct), in fact the full node is acclocated for the job since the all 
memory requested on job submission. So no other job run on this node 
until the job is end.  For billing or just for usage statistics, the 
usage should be considered not only  according to the number of cpus 
requested, but also total allocated system source should be considered.  
Is there a term for such kind of usage? totalCpuAllocateTime or 
totalNodeTime etc.
