| MPI_Comm | molpro::mpi::comm_self () |
| | Return MPI_COMM_SELF in an MPI program, or an appropriate dummy if not. More...
|
| |
| MPI_Comm | molpro::mpi::comm_global () |
| | Return the MPI communicator containing all processes available for participation in computation. If MPI support has been compiled (either mpi.h has already been included, or HAVE_MPI_H has been defined) but not yet initialised, MPI will be initialised, and then MPI_COMM_WORLD is selected. Otherwise, in the case of a program compiled with PPIDD, and for which PPIDD has already been initialised, this will be the PPIDD worker communicator. Otherwise, in the case of a program compiled with GA, and for which GA has already been initialised, this will be the GA worker communicator. Otherwise, if MPI support has is active, MPI_COMM_WORLD is selected. Otherwise (completely serial code), a place-holder is chosen. In the Molpro context, if running in mppx mode, MPI_COMM_SELF is always returned. More...
