We've been running for years with out swap on with no issues. You may
want to set MemSpecLimit in your config to reserve memory for the OS, so
that way you don't OOM the system with user jobs:

A little late here, but yes everything Hans said is correct and if you are
worried about slurm (or other critical system software) getting killed by
OOM, you can workaround it by properly configuring cgroup.

Hi Joseph,
This might depend on the rest of your configuration, but in general swap
should not be needed for anything on Linux.
BUT: you might get OOM killer messages in your system logs, and SLURM
might fall victim to the OOM killer (OOM = Out Of Memory) if you run
applications on the compute

instance with which we installed and it is working fine. We have 2 GB of SWAP
space on each node, for some purpose to make the system in full use want to
disable the SWAP memory,
Like to know if I am disabling the SWAP
