Sorry for the belated participation in this subthread of this most
excellent thread. There is another paper on the relationship between
MPI and PVM, written by Bill Gropp and me. You can find it at
http://www.mcs.anl.gov/~gropp/bib/papers/2002/mpiandpvm.pdf
We wrote it because we felt the story from the "PVM side" (the paper
below) was incomplete.

I'm not disagreeing, but wonder why PVM is basically extinct now.
that is, why was MPI considered an improvement/replacement?
As of last year, there were still quite a lot of papers on PVM. I
think
PVM is still widely used in Europe, and a lot of "old hand" cluster
people, myself included still prefer it (given their druthers). It is
much more a part of the ORIGINAL beowulfs and related linux clusters
than MPI.
MPI had a completely distinct history:
