why is MPI_Status not opaque?
by Jeff Hammond 21 Nov '22

21 Nov '22

I assume that MPI_Status is not opaque because somebody asserted that function call overhead was too much for some use cases. Was there more to it than this? Why does the standard say there is an opaque part for elements and cancelled, but not make those visible? The lack of consistency here doesn't make a lot of sense to me. MPI_Status not being opaque was a horrible mistake but I would like to be less mad about it by learning what possible reasons for it existed in 1995. Thanks, Jeff -- Jeff Hammond jeff.science(a)gmail.com http://jeffhammond.github.io/

Hi Wes, yes, thank you for pointing this out. #443 (LIS entries for MPI_T) and #160 (MPI_T binding arguments) are supposed to be Errata votes and #613 (Tools Index Operations) is close to a chapter committee change, but we would like the broader forum have a look that indeed we didn't change any semantics when we changed some wording in the cleanup. Cheers, Marc-Andre PS: I noticed that you added the 'scheduled reading' tag for all but issue #520 ... is there something missing for that one to be read?
