Just as a clarification, the MPI standard does not specify that
communication occur over sockets. LAM/MPI can use sockets for
communication, but may also use Myrinet/GM, InfiniBand VERBS, or
shared memory.
LAM/MPI only has very preliminary support for Windows, and only
running under Cygwin. We were working on better support when we
began efforts on the Open MPI project. What work has been done is
unsupported at this time, as we don't have the ability to support
more Windows development in LAM/MPI. That being said, if the Windows
support is sufficient for your work, LAM/MPI should have little
problems interoperating between Windows and Linux.
I am not sure if there are any MPI implementations currently
available that officially support such a configuration, unfortunately.
