Created attachment 9331 [details] Add support for --with ucx to rpmbuild Currently even if ucx and ucx-devel packages are installed, configure by default ignores them unless specified via ./configure --with-ucx. There is no very easy way to provide this configuration option to rpmbuild using current defines, hence added 'with_ucx" option. Other part of this patch adds requires to slurmd package on pmix and ucx. This was done to avoid confusion by users expecting srun --mpi=list to correctly transmit system capabilities. consider slurm build with pmix, but pmix is not installed on compute nodes. In that case a user running srun --mpi=list will get pmix as an option, but it will fail if pmix was not present to wireup on the nodes. The error message is quite confusing in this regard as it tells the user to check --mpi=list for acceptable types. Last issue is version coherence - without further knowledge of true dependencies, I have opted to require same pmix, ucx versions as were used during build.
Thank you Daniel. These are both included in 19.05rc1 which will be released on Tuesday: commit fa2e22c8205cd7b689a2edf926b86f301b037d29 Author: Daniel Letai <dani@letai.org.il> AuthorDate: Mon Apr 29 14:24:18 2019 -0600 slurm.spec - allow --with-ucx in rpmbuild. And require the compute nodes to have an identical installation version to avoid issues with mismatched libraries. Bug 6598. commit 35bb9afb94619382e8e4059a08b205bdbbda6e99 Author: Daniel Letai <dani@letai.org.il> AuthorDate: Mon Apr 29 14:22:13 2019 -0600 slurm.spec - allow --with-pmix in rpmbuild. And require the compute nodes to have an identical installation version to avoid issues with mismatched libraries. Bug 6598.
