Actually there is no need for such a script since

It seems that systemd-networkd exists in Fedora FC38 Linux, but not in
RHEL 8 and clones, AFAICT

Latest version is slurm-23.02.6 which one are you referring to?

if i try to request just nodes and memory, for instance:
#SBATCH -N 2
#SBATCH --mem=0
to resquest all memory on a node, and 2nodes seem sufficient for a
program that consumes 100GB, i ot this error:
sbatch: error: CPU count per node can not be satisfied

IIRC it is documented in t
Hello all,
I can't configure the slurm script correctly. My program needs 100GB of
memory, it's the only criteria. But the job always fails with an out of
memory.
Here's the cluster configuration I'm using:
SelectType=select/cons_res
SelectTypeParameters=CR_Core_Memory
partition:
DefMemPerC
Hi Max,
Thanks so much for your fast response with a solution! I didn't know that
NetworkManager (falsely) claims that the network is online as soon as the
first interface comes up :-(
Your solution of a wait-for-interfaces Systemd service makes a lot of
sense, and I'm going to try it out.
Hi,
we're not using Omni-Path but also had issues with Infiniband taking too
long and slurmd failing to start due to that.
Our solution was to implement a little wait-for-interface systemd
service which delays the network.target until the ib interface has come up.
Our discovery was that the
I'm fighting this strange scenario where slurmd is started before the
Infiniband/OPA network is fully up. The Node Health Check (NHC) executed
by slurmd then fails the node (as it should). This happens only on EL8
Linux (AlmaLinux 8.8) nodes, whereas our CentOS 7.9 nodes with
Infiniband/OPA n
