[Boost-users] boost MPI: unsupported functions & support on super computers ?

I am learning MPI, and have a few questions whether its worth using boost MPI, since I need to run on many flavours of unix.(linux clusters and AIX as a minimum) o In the boost MPI documentation it appears that many MPI functions are not supported (MPI_Bsend,etc). If I need this capability then does this mean I should not use boost MPI ? (or is there still a back door way of calling with the C API instead ? ) o Has any one managed to use boost MPI on Super-computers like: - IBM/AIX. - Fujitsu - NEC Since we need to be able swap vendors. Any help appreciated. Ta, Avi
