[MPICH] Windows distrib and Myrinet questions

[Jayesh Krishna]

Hi,
 To use the shared memory channel on windows specify "-channel shm" as an
argument to the mpiexec command (Refer to the windows developer's guide
available at http://www-unix.mcs.anl.gov/mpi/mpich/ for more details).
 MPICH2 on windows currently supports sock (tcp socket), shm (shared memory)
& ssm (sockets & shared memory) channels. Currently support for Myrinet is
not available on windows. However on linux you can use the nemesis channel
in MPICH2 (configure with nemesis:mx) to use Myrinet.
 We are planning to port nemesis to Windows in future (tentative date should
be mid next year) and then Myrinet support would be available on windows.


Regards,
Jayesh

Hi!

Does the MPICH2 Windows binary distribution (installer file) communicate via
sock only? Do I have to compile it by myself to get local communication use
shared memory?

What's the status on Myrinet support for MPICH2? Am I able to use it with
ordinary PCs if I buy a PICe Myrinet NIC, suitable cables and switches? Is
it that simple?

Greetings,
Patrick.
