Hi,
I've been tinkering around with federated SLURM and I have a few questions regarding how federated it really can be. * A federated cluster can consist out of clusters using SLURM > 17.11, these clusters then share the *same* database, correct? * Mixing different SLURM versions with a slurmdbd is not supported, correct? * Using this illustration [1], a federated cluster must use the same SLURM version as the "on-premise" cluster slurmdbd version, which runs the central database. Thus the Google Cloud Platform must run the same SLURM version as the "on-premise" one for compatibility, correct? Other concerns are e.g. different mounted file systems (Lustre), and other differences. If SLURM versions must be compatible and jobs also expect a compatible system (if cloud bursting is applied with large jobs). So the main question then becomes; how federated can federated SLURM be? It seems to be that identical sites are required in order to make this work. With the definition of federation, I was expecting to a certain extend autonomous sites, joined together in a federation. If I'm right or wrong, please let me know! :) [1] https://codelabs.developers.google.com/codelabs/hpc-slurm-federated-on-gcp/#0 -- Met vriendelijke groet, Kees de Jong De informatie opgenomen in deze e-mail kan vertrouwelijk zijn en is uitsluitend bestemd voor de geadresseerde(n).
