Any plans to add support to MPI?

[kinow]

Hi,

I created a small project with SciWin, and added my MPI test program there. But I wasn't how that'd be added, if I should s4n create ./a.out or s4n create mpirun... then I searched the issues and code for MPI, but it looks like that's not implemented yet.

SciWIn-Client comes with its custom CWL Runner (which does not support all cwltool can do, yet!)

I understand the CWL runner in SciWIn hasn't implemented all the CWL features. But I think MPI is quite common on scientific applications, at least on those executed on HPC clusters.

Any plans to add MPI support to SciWin?

I'm working on a repository for my master thesis, https://github.com/kinow/cwl-mpi, where I am using three implementations at the moment - cwltool, StreamFlow, Toil - on different HPC systems in Europe and Asia to verify e2e provenance (with CWLProv, RO-Crate, simple metadata, etc) and MPI compatibility.

I'm especially interested in the MPIRequirement, supported by cwltool and Toil.

Thanks!

Hi,
in the current funding phase we have no plans of supporting MPIRequirement due to limited personal capacities.
