Coll: Develop team-based collectives

Open minsii opened this issue 4 years ago • 0 comments

Description: OpenSHMEM 1.5 adds team-based collective. It is straightforward to translate to MPI collectives with the corresponding MPI comm.

Depend on #36

Starting point:

  • Section 9.9 Collective Routines in OpenSHMEM v1.5 spec
  • The deprecated active-set-based collectives in OSHMPI (search OSHMPI_* function in src/internal/coll_impl.h)

TODO

  • [ ] Basic implementation of team based collectives
  • [ ] Add 1-2 tests in tests/
