Hello
I'm trying to figure out how to change SLURM's behavior on gathering free
memory from nodes.
At this time 'sinfo' reports 'free' memory from the node (and not 'available'):
F.e:
#sinfo -eN -o %N,%m,%e,%C
...
NODE067,64170,14672,0/32/0/32
I can see the NODE067 has no jobs running - 0 CPUs allocated, but SLURM reports
14672 out of 64170 is available, while in fact 'free -m' command reports
'62830' as available.
[dchebota@NODE067 ~]$ free -m
total used free shared buff/cache available
Mem: 64170 704 14669 35 48795 62830
Swap: 10239 0 10239
Is it possible to change SLURM's behavior to read 'available' instead of 'free'?
'buff/cache' is considered as available memory and will be allocated when
needed.
So far, I need to run 'sync && echo 3 > /proc/sys/vm/drop_caches' to clear
'buff/cache' as workaround.
Thank you,
