I don't know much about MPI, but I thought it related to message passing/distributed workloads rather than arithmetic performance?

  Parent must have mistaken GMP for OMP, and wanted to shoot a quickie — no having to read the article! some research should be done— is it because HNers browse HN just before bed? To be honest i made the same mistake at glance… fortunately i am not mentally exhausted…

    I meant about distributing the load of calculations...

      Given the author mentions multiple cores being available, I'd guess you could use any method, including MPI, to distribute the computation. But whether you used 1 core or 10k cores, it would be nice to have a 20x speedup on each core via this arithmetic/fixed size optimization. Since that's the focus of the article, communication technologies feel pretty unrelated.
