[slurm-users] Question about memory allocation

[Mahmood Naderan]

A follow up to the previous email.

Current state of memory of nodes are

   RealMemory=64259 AllocMem=1024 FreeMem=38620 Sockets=32 Boards=1
   RealMemory=120705 AllocMem=1024 FreeMem=309 Sockets=32 Boards=1
   RealMemory=64259 AllocMem=1024 FreeMem=59334 Sockets=32 Boards=1
   RealMemory=64259 AllocMem=1024 FreeMem=282 Sockets=10 Boards=1

However, a script with

#SBATCH --mem=10GB
#SBATCH --nodes=4
#SBATCH --ntasks-per-node=5

stuck in PD state with (resources) reason.

Any idea about that?

Regards,
Mahmood
