Re: [slurm-users] error: user not found

That means the system has no idea who that user is. If you are using /etc/passwd, that file is not synched on the slurm master node(s) If you are part of a domain or other shared directory (ldap, etc), your master is likely not configured right. If you are using SSSD, it is also possible yo

[slurm-users] Scontrol update GRES stops working on Slurm 20.02.5

Hi, I recently upgraded Slurm from 19.05.5 to 20.02.5 and I noticed that I am no longer able to use the scontrol update command on GRES unless the new count is 0. For example, if I have a GRES named "test" defined and in slurm.conf > NodeName=node1 Gres=test:2 Initially, I have: $ sinfo -n no

Re: [slurm-users] EXTERNAL: Re: Memory per CPU

There are three pieces of information that may provide Useful: 1 - these are VMs and not physical servers 2 - the OS is RedHat 7.8 2 - As far as I can tell, hyperthreading is not enabled, but will check for sure 3 - when we ask for 15Gb memory - we will only get 1 CPU -Original Message- F

[slurm-users] Memory per CPU

I am working on my first ever SLURM cluster build for use as a resource manager in a JupyterHub Development environment. I have configured the cluster for SelectType of 'select/con_res' with DefMemPerCPU and MaxMemPerCPU of 16Gb. The idea is to essentially provide for jobs that run in a 1 CPU/

Re: [slurm-users] EXTERNAL: Re: Memory per CPU

I am not familiar with using Slurm with VMs, but do note that Slurm can behave a bit "unexpectedly" with memory constraints due to the memory consumed by OS, etc. E.g., if I had a 16 core machine with 64 GB of RAM and requested 16 cores with 4 GB/core, it would not fit on this machine because some

Re: [slurm-users] Memory per CPU

what leads you to believe that you're getting 2 CPU's instead of 1? 'scontrol show job ' would be a helpful first start. On Tue, Sep 29, 2020 at 9:56 AM Luecht, Jeff A wrote: > > I am working on my first ever SLURM cluster build for use as a resource > manager in a JupyterHub Development environ
