can i install this for OpenHPC 4.x on Rocky Linux 10

[luciandf]

The question is in the title. I have a cluster setup with Rocky Linux 10 using the OpenHPC 4.x recipe. But there is no slurmrestd in the repos. Can this be installed?

Hello @luciandf,

First note that Rackslab does not distribute Slurm packages in its repositories. You have to install from external repos and build Slurm packages on your own.

Then, please beware that Slurm and slurmrestd don't really support el10 at this time: it depends on http-parser-devel which is not maintained anymore and is not available on el10, see this bug for reference: https://support.schedmd.com/show_bug.cgi?id=21801. SchedMD/Nvidia has some work to do to drop this dependency.

You can install Slurm-web on el10 (eg. Rocky Linux 10) but you have to install slurmrestd on a separate host with another distribution.

thank you for your reply but I am still confused. I thought that slurmrestd had to be installed where the slurm controller resides and in my case is a master node running rocky linux 10. am i misunderstanding this?

No, there isn't such constraint. All components communicate with TCP/IP, so they can be deployed on separate hosts. This is explained in Slurm-web documentation: https://docs.rackslab.io/slurm-web/overview/architecture.html#deployment
