if i try to request just nodes and memory, for instance:
#SBATCH -N 2
#SBATCH --mem=0
to resquest all memory on a node, and 2nodes seem sufficient for a
program that consumes 100GB, i ot this error:
sbatch: error: CPU count per node can not be satisfied
sbatch: error: Batch job submission failed: Requested node configuration
is not available
thanks

Hello all,
I can't configure the slurm script correctly. My program needs 100GB of
memory, it's the only criteria. But the job always fails with an out of
memory.
Here's the cluster configuration I'm using:
SelectType=select/cons_res
SelectTypeParameters=CR_Core_Memory
partition:
DefMemPerCPU=5770 MaxMemPerCPU=5778
TRES=cpu=5056,mem=30020000M,node=158
for each node: CPUAlloc=32 RealMemory=190000 AllocMem=184640
my script contains:
#SBATCH -N 5
#SBATCH --ntasks=60
#SBATCH --mem-per-cpu=1500M
#SBATCH --cpus-per-task=1
...
mpirun ../zsimpletest_analyse
when it fails, sacct gives the follwing information:
JobID JobName Elapsed NCPUS TotalCPU CPUTime
ReqMem MaxRSS MaxDiskRead MaxDiskWrite State ExitCode

i don't understand why MaxRSS=21M leads to "out of memory" with 16cpus
and 1500M per cpu (24M)
if anybody can help?
thanks in advance
