Re: [slurm-users] slurm sinfo format memory
another option besides those mentioned would be to frontend sinfo with jq/python and parse the data through json/yaml On Thu, Jul 20, 2023 at 12:28 PM Arsene Marian Alain wrote: > > > > Dear slurm users, > > > > I would like to see the following information of my nodes "hostname, total > mem, free mem and cpus".

Just my 2 cents: The old "-o" options flag should be replaced by Slurm's more modern "-O" option which uses readable parameters and allows more output fields than -o, for example: sinfo -O "NodeHost,CPUsState:20,Memory:20,FreeMem:20,StateComplete:30" /Ole

Other than that, piping the output into a script/program that does whatever scaling you want will give you eaxctly what you want, as you'll have full control over things.
Re: [slurm-users] slurm sinfo format memory
Looks like Slurm itself only supports that format(in MB unit). Slurm commands output format is not very user friendly to me. If it can add some easy options, like for the output info of sinfo command in this email thread, how about adding support for lazy options, like sinfo -ABC, etc. For the desired format in GB, one workaround may be to prepare a wrapper shell script, read in the sinfo output, and convert the MB to GB and print out to the screen.

[slurm-users] slurm sinfo format memory
Dear slurm users, I would like to see the following information of my nodes "hostname, total mem, free mem and cpus". So, I used 'sinfo -o "%8n %8m %8e %C"' but in the output it shows me the memory in MB like "190560" and I need it in GB (without decimals if possible) like "190GB". Any ideas or suggestions on how I can do that? current output: HOSTNAME MEMORY FREE_MEM CPUS(A/I/O/T) node01 190560 125249 60/4/0/64 node02 190560 171944 40/24/0/64 node05 93280 91584 0/40/0/40 node06 513120 509448 0/96/0/96 node07 513120 512086 0/96/0/96 node08 513120 512328 0/96/0/96 node09 513120 512304 0/96/0/96 desired output: HOSTNAME MEMORY FREE_MEM CPUS(A/I/O/T) node01 190GB 125GB 60/4/0/64 node02 190GB 171GB 40/24/0/64 node05 93GB 91GB0/40/0/40 node06 512GB 500GB 0/96/0/96 node07 512GB 512GB 0/96/0/96 node08 512GB 512GB 0/96/0/96 node09 512GB 512GB 0/96/0/96 I would appreciate any help. Thank you. Best Regards, Alain
