Peter,
The MPICH2 Windows binary distribution comes with all the flavors of MPICH2
pre-built. You can select the multi-threaded socket channel build at
runtime using various mechanisms:
1) Use the -channel option to mpiexec.
"mpiexec -channel mt -n 3 myapp"
2) Use the wmpiconfig tool to set the default channel to "mt".
3) Use the process manager, smpd, to set the default channel.
"smpd -set channel mt"
4) Use an environment variable in the command prompt where you run mpiexec.
SMPD_OPTION_CHANNEL=mt

Subject: RE: [MPICH] Trying to build for Fedora 3
Many thanks Rajeev. Will give it a whirl in the morning when I am back at my
Linux lab. Am looking forward to letting independent threads generate and
receive specific messages.
May I ask a related question? How does the standard Windows MPICH2 build
behave when threads are making MPICH2 calls? Would one need to rebuild
MPICH2 first?
Best,
Peter.
