Subject: [OMPI users] reg. heterogeneous cluster confguration

Hello all,

I have a couple of questions regarding the support for heterogeneous
clusters. I appreciate your responses to clarify the same.

1) Endian conversion - Open MPI does automatic endian conversion as long as
the size of the data types on the communicating nodes is equal. This support
is fully qualified from v1.1. Is this a correct statement?
2) Windows and *nix clusters - Is it possible to have a single MPI
application spawned and executed across a cluster of mixed operating systems
like Windows & other flavours of UNIX (Solaris, Linux, AIX) etc? My
understanding is from MPICH2, using SMPD process manager, it is.

Thank you for your time.
