Does anyone knows whether the parastation MPI is an active project still, because the github doesn’t show so many recent changes? There's a number of different repos under that umbrella, and whilst psmpi does look active it seems the psmgmt one has had more commits recently. So it does look active to me. https://github.com/ParaStation/ All the best. Chris -- Chris Samuel : http://www.csamuel.org/ : Berkeley, CA, USA

[slurm-users] parastation (mpi)
Hello all, Some of scientists found the toolchains based on ParaStation to be faster than those utilizing openMPI or impi. I couldn’t find any eb files for toolchains based on this MPI implementation. My colleagues are using this toolchains on Jülich cluster (especially Juwels). My question is whether these eb files can be shared ? I would be interested especially in the ones using NVHPC as core module. Does anyone knows whether the parastation MPI is an active project still, because the github doesn’t show so many recent changes? Many thanks in advance and sorry if I overlooked something in eb files of version 4.8.1. Cheers, -Frank Heckes

Hello, Some days ago, I started to configure a new server with SLURM 23.02.5. Yesterday, I read in this mailing list that version 23.11.0 was released, so today I have compiled this latest version. However, after starting slurmdbd (with a database upgrade), I have got problems with slurmctld, because of "select/cons_res" has dissapeard and, now, this parameter must be changed to "select_cons/tres". If I change this, what is the impact in the system/cluster? What are the differences between "select_cons/res" and "select_cons/tres" if in newest versions it is mandatory to configure in this way? Thanks.
Re: [slurm-users] slurm comunication between versions
