Thank you for the answers.
is the RealMemory will be decided on the Total Memory value or total usable
memory value.
i mean if a node having 256GB RAM but free -g will tell about only 251 GB.
deda1x1591:~ # free -g
total used free shared buffers cached
Mem: 251 67 184 6 0 47
so we can add the value is 251*1024 MB or 256*1024MB. or is there any
slurm command which will provide me the value to add.
Regards
Navin.
