Another problem I've run into (this is OT) is the '--enable-threads'
option. I know (from other mailing list posts) that this doesn't work
in any of the releases, but how about CVS? If it doesn't work, why
include the option in the configure script? It seems like with the trend
of cramming more cores into a single box, threads would become more and
more important. MPI just seems kind of ridiculous for work on a single
machine, when you could use threads.
It isn't as thick-brained as it may seem. If your local MPI
implementation is SMP and/or multi-core aware, it will use shared
memory, local bus or cache for the communication calls. This has alway
worked well enough on, e.g., SGI multi-cpu machines (e.g., PowerChallenge).
Nevertheless, on newer architectures, threads would ultimately be the
better choice. They're working on it and according to David van der
Spoel it will be in 4.0 (that was on the Developer's list in May '04...
Brrrrr, as David would put it ;-).
