Any thoughts on parallel programming. I was looking at something
about Chapel
and X10 languages etc. for parallelism, and it looks interesting.
I know that
it is still an area of active research, and it is not yet (far
from?) done,
but anyone have thoughts on this as future direction? Thank you.
I just finished reading "Parallel Programmability and the Chapel
Language" by Chamberlain, Callahan and Zima.
A very nice read, and overview of several languages and approaches.
Still I stand by my earlier view, an MPI like approach is more
flexible, but indeed having a nice parallel implementation of
distributed arrays (which on MPI one can have using Global Arrays for
example), can be very useful.
I think that a language like D can hide these behind wrapper objects,
and reach for these objects (that are not the only ones present in a
complex parallel program) an expressivity similar to chapel using the
approach I have in blip.
A direct implementation might be more efficient on shared memory
machines though.
