Arnuld, You may be looking for the srun parameter or configuration option of "--oversubscribe" for CPU as that is the limiting factor now. S. Zhang On 2024/06/21 2:48, Brian Andrus via slurm-users wrote: Well, if I am reading this right, it makes sense. Every job will need at least 1 core j

Carl, You cannot tell from the binary alone. It looks like you just did an apt-get install slurm or such under Ubuntu. Would that be right? You may be able to look at the package and see info about the build environment. Generally, it is best to build slurm yourself for the environment it is

We're seeing SLURM mis-behaving on one of your clusters, that runs Ubuntu 22.04. Ampng other problems, we see an error-message regarding a missing library version that would have been shipped on Ubuntu 20.04 not 22.04. It's not clear that the library is being called from a SLURM component or

Well, if I am reading this right, it makes sense. Every job will need at least 1 core just to run and if there are only 4 cores on the machine, one would expect a max of 4 jobs to run. Brian Andrus On 6/20/2024 5:24 AM, Arnuld via slurm-users wrote: I have a machine with a quad-core CPU and a

I have a machine with a quad-core CPU and an Nvidia GPU with 3500+ cores. I want to run around 10 jobs in parallel on the GPU (mostly are CUDA based jobs). PROBLEM: Each job asks for only 100 shards (runs usually for a minute or so), then I should be able to run 3500/100 = 35 jobs in parallel but

Hello, I'd like to ask if there is any safe method to rename an existing slurm user to new username with the same uid? As for linux itself, it's quite common to have 2 user share the same uid. So if we already have 2 system users, for example Bob(uid=1500) and HPCBob(uid=1500), and the HPCBob
