I tried using ntasks and cpus-per-task to get all 32 cores. So I added
--ntasks=# --cpus-per-task=N to th sbatch command so that it now looks
like:
sbatch --nodes=1 --ntasks=1 --cpus-per-task=32

Good morning,
I'm running an NPB test, bt.C that is OpenMP and built using NV HPC SDK
(version 25.1). I run it on a compute node by ssh-ing to the node. It runs
in about 19.6 seconds.
Then I run the code using a simple job:
Command to submit job: sbatch --nodes=1 run-npb-omp

Thanks! I admit I'm not that experienced in Bash. I will give this a whirl
as a test.
In the meantime, let ask, what is the "canonical" way to create the host
list? It would be nice to have this in the Slurm FAQ somewhere.
Thanks!

Good afternoon,
I know this question has been asked a million times, but what is the
canonical way to convert the list of nodes for a job that is container in a
Slurm variable, I use SLURM_JOB_NODELIST, to a host list appropriate for
mpirun in OpenMPI (perhaps MPICH as well)?
Before anyone says,
I think all of the replies point to --exclusive being your best solution
(only solution?).
You need to know exactly the maximum number of cores a particular
application or applications will use. Then you allow other applications to
use the unused cores. Otherwise, at some point when the applicatio

Good morning,
I have an Ubuntu 22.04 server where I installed Slurm from the Ubuntu
packages. I now want to install pyxis but it says I need the Slurm sources.
In Ubuntu 22.04, is there a package that has the source code? How to
download the sources I need from github?
Thanks!

Good afternoon,
I'm working on a cluster of NVIDIA DGX A100's that is using BCM 10 (Base
Command Manager which is based on Bright Cluster Manager). I ran into an
error and only just learned that Slurm and Weka don't get along (presumably
because Weka pins their client threads to cores). I read thr

Good afternoon,
I have a very simple two node cluster using Warewulf 4.3. I was following
some instructions on how to install the OpenHPC Slurm binaries (server and
client). I booted the compute node and the Slurm Server says it's in an
unknown state. This hasn't happened to me before but I would
