Greetings,

Yes, I referenced to the man page but :

request h_vmem is per slot whereas h_vmem for host is host level and
for all slots.
In this situation, h_vmem job's  requested  should compare with h_vmem
host divide by all slots.

the following relation must be checked for any job:
requested h_vmem <= host level h_vmem / $num_proc

Can I do that via RQS?
any suggestion would be appriciated.


Regards
Rustaee
