[MPICH] reg. heterogeneous cluster

[Kalyana Krishna]

Hi everyone,

I have a couple of questions regarding support of heterogeneous
clusters with mpich2.

1) With SMPD process manager, is it possible to launch a single MPI
application across *NIX and Windows platform?
2) Does MPICH2 do automatic conversion between machines of different
binary formats (big endian and little endian) as long as the size of
the data types is same on both platforms?
3) If answer to 1 & 2 is yes, should the Infiniband driver stack on
all machines be from the same vendor? (OpenIB, QLogic (Silverstorm),
Cisco etc)? Or can Linux have OpenIB stack and windows have vendor
stack and still be able to participate in a single MPI application?

thank you for your time.

regards,
Kalyan
