[slurm-users] Problems with salloc

[Gestió Servidors via slurm-users]

Hello,

 

I am getting some problems with “salloc” execution. My cluster is running SLURM v23.11.0. I’m going to explain problems:

1. My first problem is that until some previous version (I can’t remember what version exactly), when I ran a “salloc”, I got a console inside the assigned host. Then, I could execute whatever I wanted. However, now, after execute “salloc” (without forcing host), SLURM always tries to assign me the last host where a job has been executed. But if that host is now powered off, salloc waits and waits but not tries to connect to other host
2. Second problem is that previous execution gives me a host (the host is powered on), my session continues in the allocation host, not in the assigned host. So if I want to execute some program, I need to run with “srun”. Is there anyway to go directly to the assigned host?
3. Third problem is a question. How can I limit the hosts where I (as cluster admin) allow to run a “salloc”? For example, I would like that when a user runs a “salloc”, it were execute always in a partition with “x” hosts, avoiding SLURM to assign me a host of the list of hosts.

 

Thanks.
