3 # Script to generate Fortran 2003 wrappers for FFTW's MPI functions. This
|
|
Chris@19
|
4 # is necessary because MPI provides no way to deal with C MPI_Comm handles
|
|
Chris@19
|
5 # from Fortran (where MPI_Comm == integer), but does provide a way to
|
|
Chris@19
|
6 # deal with Fortran MPI_Comm handles from C (via MPI_Comm_f2c). So,
|
|
Chris@19
|
7 # every FFTW function that takes an MPI_Comm argument needs a wrapper
|
|
Chris@19
|
8 # function that takes a Fortran integer and converts it to MPI_Comm.
