This has got be one of the coolest posts ever on this list :)
Still, there is a moot point. The hard fact is that there is no parallel
programming language despite all the claims. In my opinion the only one that
comes close is HPF and a few of the functional PL compilers (like ghc), but I
never had the leisure to try them so that is assuming you trust the papers.
My programming language of choice for parallel programming is C++, since it is
a low level language (in spite of what you may think) but still suffficiently
abstract to allow me to code in a rather modular and comprehensible way. C++
is eligible for the role of assembly in supercomputing. With C++/MPI, I can
write generic communication routines, object-based data structure libs and
such, none of which is really possible in the two remaining culprits.
My order of preference for a parallel programming project would be
This is the best we can do with three languages that all suck.
I had been planning to write a parallel programming language that would have a
nice functional semantics and efficient execution during my msc. thesis. I
was thinking, maybe I could find a program representation through which an
automatic code/data distribution/replication could be derived (overly
simplifying things) What I found was that the thesis exploded in my hand and
I had to find another subject :) If somebody offers me an inordinate amount
of resources, I can get back to that subject gladly. I guarantee no results
PS: I think I truly hated C when I coded a parallel quicksort routine for a
lamer at our department (I can give you his name so you can avoid him in the
future). Besides, he didn't pay me the complete amount of money he promised.
