> These are the future work items for the tools side document that I know about.
> From our wiki page:
> • A scalable version of a process acquisition interface to identify and locate all processes which are part of an MPI job.
> • An interface to look for and locate tool DLLs.
> • An interface to inspect message queues.
> • An interface to understand progress in collective communication.
> • An interface to query additional semantic information for opaque MPI handles.
> • An MPI morph layer (and the necessary requirements to make this work)
> I don't know what the MPI morph layer is. Maybe Jeff or Martin have this information?
The morph layer came from the idea of how can we add a small tool layer on top of MPI A, so that a code compiled for MPI B can run on top of MPI A. I don't think this will be that easy to do and I am not sure if this is something for the side document, since it would probably require changes in the first party interface.
> Additionally, for MPIR we want to add routines to query which resource manager is being used and what the command for bulk launch is (e.g. srun, mpirun).
> Does anyone else have others?
