There isn't any these days, there used to be support for BLCR but that's
been dropped as BLCR is no more.
I know from talking with SchedMD they are of the opinion that any

We use a scenario that is analogous to yours using features. Features
are defined in slurm.conf and are associated with nodes from-which a
job may be submitted, as an administratively, configuration-managed
authoritative source. (NodeName=xx-login State=FUTURE

Hi Thomas,
We do not need to lock out jobs from the other nodes. All our jobs specify
constraints and will be scheduled on nodes accordingly.
To follow your example:
* a job with unsatisfiable constraint foo is submitted
* the scanning tool detects the job queued and schedules another j
Probably your best bet would be to to use the job_submit.lua script and
block using that.

Hi,
what's the current status of the checkpointing support in SLURM? There was a
CRIU plugin mentioned:
https://slurm.schedmd.com/SLUG16/ciemat-cr.pdf
But it doesn't exist in SLURM 19.05.5 on Ubuntu 20.04. And the manual page
mentions an OpenMPI plugin only.
Best,

Stefan Stäglich,
Making the certificate globally-available on the host may not always be
permissible. If I were you, I'd write/suggest a modification to the plugin to
make the CA path (CURLOPT_CAPATH) and verification itself
(CURLOPT_SSL_VERIFYPEER) configurable in Slurm. They are both straightforward
options
Hi,
all except of /etc/ssl/certs/ca-certificates.crt is ignored. So I've copied it
to /usr/local/share/ca-certificates/ and run update-ca-certificates.
Now it's working :)

Stefan

i would look into using mellanox ofed with rdma-core, as it is what
mellanox is shifting towards or has already done (not sure what 4.9 has

We’ve run a similar setup since I moved to Slurm 3 years ago, with no issues.
Could you share partition definitions from your slurm.conf?
When you see a bunch of jobs pending, which ones have a reason of “Resources”?
Those should be the next ones to run, and ones with a reason of “Priority” are

Hello all,
we are experiencing an issue in our cluster where sometimes entire nodes
remain idle while jobs are pending in the queue that could run on the
nodes in question.
Our node topology is a bit special where almost all our nodes are in one
common partition a subset of all those nodes a
