I'm not going to say Slurm is great (its API:s are awfully inconsistent and there's a lot of code churn between versions leading to subtle behaviour changes in prod), but it's an invaluable and reliable tool. As someone who manages Slurm clusters in academic HPC as a major part of my job, I'm not at all happy to see this and quite worried that the development and maintenance of Slurm will be broken by the inevitable market volatility.
i thought nobody use slurm/pbs anymore..its all kubernetes and mlops nowadays?
except universities? cfd? other engineering stuffs?
Except literally everyone who needs a functioning queue system.
Heavily used in hpc
Both slurm, and even more so HTCondor, power most of the major computationally-expensive physics projects worldwide (all the LHC experiments, LIGO, IceCube, etc.)
It's not just for universities and for CFD. Slurm is the primary job scheduler at Los Alamos National Lab. I know other federal labs that use it too. It is just really popular in general.
like. look at it this way. before (what? when?) nvidia was a gpu maker and yearly revenue was maybe us$10b. and after. or now. its an accelerator maker and its revenue is nearer us$200b. im imagining the slurm/pbs market was, and still is, a fraction of that original us$10b. and the new us$190b are the kubernetes+mlops kind of thing. i wonder if theres a public breakdown of this somewhere...
