Copy link

  1. typo

Finally, if I link my application against against a specific MPI implemntation, I must run the resulting application with a compatible mpirun.

  1. See mpi4py CI pipelines for more nasty examples like Rust MPI.

  2. Love this point!

The question is whether the MPI user community cares more about these 100 nanoseconds versus the hours and days it takes humans to build the MPI software ecosystem twice, three times, or more, because of the lack of a standard ABI.

I think this is a key point that you should amplify. Basically, the trade off in developer productivity versus performance.

Great article! I hope this happens!
