Greetings ladies and gentlemen, I believe that the last version of OSX to have OpenMPI shipped with the dev tools or the OS was Snow Leopard. That version I believe was version OMPI 1.29.
I am starting to get back to working with MPI myself. The last time I worked with MPI, I basically wrapped the C function into Objective-C. Often I would let Objective-C do the marshaling for me, and have MPI do the message passing itself. I have read that OMPI from source works on Mountain Lion, but there are some dependencies to make it work with LLVM and to make GCC-Fortran transition to LLVM. If there are some gurus out there who have done this fill us with wisdom.

There is also C++ and Fortran support, while the C++ interface is deprecated as the C one will do here too. > Thanks in advance for any info that you can give me; I really like the idea > to use MPI for scientific applications, but I am totally new to this (I have > experience in C++ on Windows, and a bit of Objective-C on mac).

Can you issue: $ ompi_info on the command line? As MPI is a standard which is not targeting any specific platform, most of the tutorials should apply here too, as long as they don't access any OS specific functions. For an Objective-C application: $ mpicc -ObjC -framework Foundation -framework CoreLocation .... -- Reuti _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
