Sure. MS did this, no doubt. And as you note below, no sooner do they
get it in when they begin the borgification of MPI, just as they've
borgified java, c, c++, and anything in the Universe they can sucker
somebody into buying in borgified form.
Borgifying MPI is the most humorous thing in the Universe, BTW, given
its historical origins -- it was basically a language written
(reluctantly!) by supercomputer vendors when the US government got tired
of paying for all their important codes to be ported to each new
generation of proprietary hardware with its proprietary low level calls.
MS is doubtless trying to figure out just how much of that they can
undo while building up a big enough market share and enough vendors of
closed source applications written with their borgisms that they can...
Oh wait. It IS GPL. Do you think that they actually read it?
However, I was really referring to the other aspects of program
development and performance tuning associated with using a closed source
Resistance is Futile.
