<div dir="ltr">Dear Forum Members:<div><br></div><div>We would like to schedule a meeting about "new language bindings" as an action item from our virtual last meeting (just ended).</div><div><br></div><div>This covers this topic with sub-topics raised in the Virtual Meeting (plus more):</div><div><br></div><div>"MPI object that contains an entire language binding" ... which is due to Jeff Squyres :-)</div><div><br></div><div>With these questions (among others to be answered)</div><div>--- How to descrtibe this, such as with a normative header, from C, C++, Fortran</div><div>--- How to guarantee that a given library (e.g., MPI-4) can also allow internal and layered components (e.g., MPI3) to work.</div><div>[Imagine an MPI-3 based library receiving a communicator from an MPI-4 main program in this way]</div><div>--- How this approach can alleviate the need for the following</div><div>a) _X Big MPI APIs, because the MPI.fn() [maybe MPI->fn() in C] provides the old and new APIs either through multiplicity</div><div>of APIs, or through compile-time polymorphism</div><div>b) Explanation of how this is strongly typed at compile time</div><div>c) Explanation of how this works with PMPI and tools (or what changes it may imply)</div><div>d) DIscussion of how this could interact with</div><div>--- eliminating MPI_COMM_WORLD and new MPI_Init() variants</div><div>--- Sessions and Topological groups</div><div>--- Subset APIs</div><div>--- Fault Tolerance</div><div>[others?]</div><div>e) Timing of such a proposal once we agree to formalize it.
