[slurm-users] Re: FairShare if there's only one account?

fairshare=parent sets the user association to effectively compete at the account level, so this is behaving as intended.  It's effectively ignoring the users' usage when competing with others inside the same account.  That is not want you want.  Give them all the same numeric value, not parent.

[slurm-users] Re: Node (anti?) Feature / attribute

We did something like this in the past but from C.  However, modifying the features was painful if the user did any interesting syntax. What we are doing now is using --extra for that purpose.  The nodes boot up with SLURMD_OPTIONS="--extra {\\\"os\\\":\\\"rhel9\\\"}" or similar.  Users can re

David, There are several possible answers depending on what you hope to accomplish.  What exactly is the issue that you're trying to solve? Do you mean that you have users who need, say, 8 GB of RAM per core but you only have 4 GB of RAM per core on the system and you want a way to account fo

Re: [slurm-users] FairShare

It's really similar to a binary search tree.  Within each account, it is Shares / Usage to calculate the Level FS.  See https://slurm.schedmd.com/SUG14/fair_tree.pdf has more details, starting at page 34 or so.  It even has an "animation". Ryan On 12/2/20 10:22 AM, Micheal Krombopulous wrote:

Re: [slurm-users] FairShare

Micheal, Details are at https://slurm.schedmd.com/fair_tree.html . If they have the same shares and usage as each other, they will have the same fair share value.  One thing to keep in mind is that sshare rounds or truncates the values, so 0.00 do

Re: [slurm-users] Is that possible to submit jobs to a Slurm cluster right from a developer's PC

Be careful with this approach.  You also need the same munge key installed everywhere.  If the developers have root on their own system, they can submit jobs and run Slurm commands as any user. ssh sounds significantly safer.  A quick and easy way to make sure that users don't abuse the system
