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
1) C++
2) FORTRAN
3) C

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 
however ;)

Cheers,

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.
