Hi, Fujitsu MPI, which is currently based on Open MPI v4.0.x, supports Java bindings.
It is because one of our customers requested to support it decade or so ago. I don't know users are still using it. Fujitsu MPI development team regularly receives trouble/request reports but does not receive Java ones recently. So users are few, if any. We Fujitsu don't mind dropping Java binding in Open MPI v5.0.x. Thanks, Takahiro Kawashima, Fujitsu > During a planning meeting for Open MPI v5.0.0 today, the question came up: is > anyone using the Open MPI Java bindings? > > These bindings are not official MPI Forum bindings -- they are an Open > MPI-specific extension. They were added a few years ago as a result of a > research project. > > We ask this question because we're wondering if it's worthwhile to bring > these bindings forward to the v5.0.x series, or whether we should remove them > from v5.0.x, and just leave them available back in the v4.0.x and v4.1.x > series. > > Please reply here to this list if you are using the Open MPI Java bindings, > or know of anyone who is using them. > > Thank you!
