MPI BigCount

MPI Working Group for Large Counts

As of Q4 2019, this WG is working on two main issues for MPI-4.0 and beyond (this work does not apply to MPI-3.x or earlier):

  1. Python-izing the MPI bindings in the LaTeX.
    • I.e., converting the raw LaTeX for the C, mpif.h, use mpi, and use mpi_f08 bindings embedded all throughout the .tex files for the MPI standard to be small blocks of Python (which then, in turn, generate the required LaTeX).
    • See the description on this pull request for more of an explanation.
  2. Embiggening the "count" parameters.
    • One goal, for example, is to be able to pass more than 2GB (i.e., INT_MAX) as the "count" parameter in a single call to MPI_Send().

Pythonizing instructions for chapter authors

If you are a chapter author or are otherwise editing the LaTeX of the MPI Standard, see this wiki page for instructions on how to write/edit bindings in the LaTeX source code.
