Parallel Programming Questions
Scott Robert Ladd
Is anyone doing parallel programming in C++?
I'm asking about true parallel programming for multiprocessor mainframes and
clusters; threads (light-weight processes) are something different (although
perhaps people need to know about them, too?)
What I'm looking for is some sense of current practice in developing
applications -- which technologies people are using (MPICH? Native
processes? Linux? Beowulf? Windows?) and the applications they're working
on.
My motivation? I've just finished a couple of parallel programming projects,
and I'm trying to decide what sort of articles to add to my web site (URL
below).
Thanks.

Maybe you could start with the difference between the problems faced
when programming for multiple processors, and the problems faced when
programming for multiple threads.
I realize that with multiple processors, synchronization issues are
even more essential than in multiple thread environments -- the latter
could have a task switch in the middle of a data read, but the former
could have two processors doing ALL data reads at the same time.
Other than that, I'm naive enough to think that the issues faced in
both situations are identical -- and so are the solutions. What you
say above implies that I'm wrong about that -- so that would be a
great first article, although perhaps more basic than you had planned.
