Thanks for the confirmation, Jacob. Is it possible to change this behavior? If there's no config parameter for this, I'm fine with changing the SLURM code to achieve this. It sounds like it'd be a very local change. As for cloud setups it's a pretty common goal to minimize the number of nodes, I'd

Currently, Slurm marks allocated nodes needing to be booted as unavailable for other jobs until they are booted. Once the node is booted, then normal packing should happen. Jacob On Wed, Sep 12, 2018 at 7:30 AM, Eli V wrote: > Sound like you figured it out, but I mis-remembered and switched th

[slurm-users] Using GRES to manage GPUs, but unable to assign specific CPUs to specific GPUs

2018-09-12 Thread Randall Radmer
I’m using GRES to manage eight GPUs in a node on a new Slurm cluster and am trying to bind specific CPUs to specific GPUs, but it’s not working as I expected. I am able to request a specific number of GPUs, but the CPU assignment seems wrong. I assume I’m missing something obvious, but just can't

So useradd is adding a Linux user, which sacctmgr creates a Slurm user. What we do is that we run AD for our Linux user managment.  We then in our job submit lua script look to see if the user has an account in slurm and if they don't we create it. Another way would be to make all your Linux

Sound like you figured it out, but I mis-remembered and switched the case on CR_LLN. Setting it spreads the jobs out across the nodes, not filling one up first. Also, I believe it can be set per partition as well. On Tue, Sep 11, 2018 at 5:24 PM Felix Wolfheimer wrote: > > Thanks for the input! I
