[MPICH] Re: 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
