Re: [slurm-users] Exclude Slurm packages from the EPEL yum repository

Lots of mixed reactions here, many in favor (and grateful) for the add to EPEL, many much less enthusiastic. I cannot rename an EPEL package that is now in the wild without providing an upgrade path to the new name. Such an upgrade path would defeat the purpose of the rename and won't help at a

Yes, I agree. The user gave me a minimal description of the problem, so thought he was seeing the error as soon as he called salloc. After pressing him for more information, it turns out he had been working in the salloc session for several hours before the problem occured, so I think this just

Re: [slurm-users] salloc: error: Error on msg accept socket: Too many open files

Run salloc with a smaller number of nodes or tasks, then take a look at lsof (or some other favorite means of finding IP connections). IIRC, each srun/node in the allocation needs 70-80 IP connections with the node running salloc, so a large node count can overwhelm the default allocation of fi

Re: [slurm-users] salloc: error: Error on msg accept socket: Too many open files

That sounds like a linux issue. You probably need to reset the max limit for file descriptors someplace. Maybe start here: https://rtcamp.com/tutorials/linux/increase-open-files-limit/ On 2/2/21 11:50 AM, Prentice Bisbal wrote: Has anyone seen this error message before? A user just reported it
