Currently I've set: sacctmgr modify account where name=account1 set fairshare=parent sacctmgr modify account where name=account2 set fairshare=parent sacctmgr modify account where name=account3 set fairshare=parent sacctmgr modify account where name=account4 set fairshare=parent sacctmgr modify account where name=account5 set fairshare=parent
sacctmgr modify user where name=owner11 account=account1 partition=partition1 set fairshare=47 sacctmgr modify user where name=owner12 account=account1 partition=partition1 set fairshare=13 sacctmgr modify user where name=owner13 account=account1 partition=partition1 set fairshare=40 sacctmgr modify user where name=owner14 account=account1 partition=prtitition1 set fairshare=0 ... sacctmgr modify user where name=owner1N account=account1 partition=account1 set fairshare=0 Is this correct or not? I mean, If I remove the fairshare=parent setting from account1... what value should I put there then? What I want to obtain is that when the three owners (owner11, owner12 and owner13) do submit lots of jibs using "-A account1 -p partition1" their usage will be 47 %, 13 % and 40 % respectively. Their usage should also be independent from what all other users are doing on all other accounts. I also want to disable the fairshare portion of the total priority for owner14, owner15... owner1N. fairshare=0 at user level should make this possible right? ________________________________ From: Lipari, Don [[email protected]] Sent: Tuesday, January 29, 2013 12:44 AM To: slurm-dev Subject: [slurm-dev] RE: Independent FairShare Configuration for N Cluster Segments Matt, To allow the jobs from each owner (11, 12, and 13) to be prioritized based on their usage, do not include the fairshare=parent setting. Otherwise, your settings should result in usage that reflects the shares you have configured, assuming all three owners have been submitting enough jobs to the queue. To check, run “sshare -a” from time to time. Don From: Guglielmi Matteo [mailto:[email protected]] Sent: Monday, January 28, 2013 7:47 AM To: slurm-dev Subject: [slurm-dev] Independent FairShare Configuration for N Cluster Segments I have slurm running on a confederation of clusters but at slurm level, I've defined a single cluster. For each physical cluster I've created an account and to each account I've associated the corresponding "owner" users. To each account I've also associated a single partition which includes all the nodes of that particular cluster. root | | +-----------+-----------+----------+-----------+ | | | | | account1 account2 account3 account4 account5 | | | | | + owner11 + owner21 + + + owner51 + owner12 + owner22 ... ... + owner52 ~ ~ ~ + owner1N + owner2K + owner5J Because each owner user is associated to a single account, I need to configure the faishare so that the priority for each user belonging the same account is not affected by what's happening to the accounts. So, if I set: fairshare=parent for all 5 accounts and, for example: fairshare=47 (owner11) fairshare=13 (owner12) fairshare=40 (owner13) fairshare=0 (owner14,... owner1N) do I get the corresponding shares of 47%, 13% and 40% for the three owners of account1? Are the corresponding shares independent from the load of experienced by the other cluster segments (account2,... account5)? Thanks, --matt
