Yes, therefore MPI_SUBARRAYS_SUPPORTED==.TRUE. in mpif.h is a high-quality option, it is not mandatory.

Ah, right. It appears acceptable to define MPI_SUBARRAYS_SUPPORTED = .true. in the mpi_f08 module and .false. in both the mpi module and the mpif.h file. This eliminates the need to implement 3b, which simplifies the initial implementation. [And, perhaps, encourages users to migrate to the mpi_f08 module...] Cheers, Bill -- Bill Long [email protected] Fortran Technical Support & voice: 651-605-9024 Bioinformatics Software Development fax: 651-605-9142 Cray Inc./Cray Plaza, Suite 210/380 Jackson St./St. Paul, MN 55101
