Missed Pythonization routines
by Jeff Squyres (jsquyres) 10 Sep '20

10 Sep '20

A handful of routines in the bindings chapter accidentally escaped Pythonization. Martin R. just Pythonized them: https://github.com/mpi-forum/mpi-standard/pull/276 Does this qualify as an errata? (i.e., does it need a reading+vote) Or is it an editorial fix? Or is is a chapter committee change? Or ...? -- Jeff Squyres jsquyres(a)cisco.com

Errata reading: add missing "const" into two C bindings
by Jeff Squyres (jsquyres) 09 Sep '20

09 Sep '20

Two in a single day: announcing another all-new, exciting errata item! https://github.com/mpi-forum/mpi-issues/issues/307 The C bindings for MPI_STATUS_F082C and MPI_STATUS_C2F08 are missing "const". 3.x and 4.0 PRs and PDFs are attached to the issue. Enjoy! -- Jeff Squyres jsquyres(a)cisco.com

Errata reading: MPI_F_STATUS_SIZE et al.
by Jeff Squyres (jsquyres) 09 Sep '20

09 Sep '20

Announcing an all-new, exciting errata item! https://github.com/mpi-forum/mpi-issues/issues/306 In MPI-3.1, the Fortran INTEGER-array-style status object constant MPI_STATUS_SIZE, MPI_SOURCE, MPI_TAG, and MPI_ERROR are explicitly only defined in Fortran. This does not make sense, because Fortran INTEGER-array-style status objects are also accessible in C. This errata therefore creates C versions of these constants: MPI_F_STATUS_SIZE, MPI_F_SOURCE, MPI_F_TAG, and MPI_F_ERROR. Mercifully, it's a pretty short text change. The v3.x PR and PDF and v4.0 PR and PDF are linked from the above issue. Enjoy. -- Jeff Squyres jsquyres(a)cisco.com
