Parallel Three-Dimensional Fast Fourier Transforms 2.2 (Default branch)

Parallel Three-Dimensional Fast FourierTransforms, dubbed P3DFFT, is a library forcomputing 3D FFTs using 2D (pencil) decomposition.It is written using Fortran with MPI, and is tunedto work on multiple single-CPU systems (up to32768 of them). It is built to leveragehigh-performance serial 1D FFT libraries, such asFFTW or ESSL.License: Public DomainChanges:
This version provides accurate treatment of the 0 and N/2 modes in the complex sequence in Fourier space.

MPI_Group_c2f(3)						      LAM/MPI							  MPI_Group_c2f(3)

NAME

       MPI_Group_c2f -	Convert a group handle from its C representation to its Fortran representation

SYNOPSIS

       #include <mpi.h>
       MPI_Fint
       MPI_Group_c2f(MPI_Group group)

INPUT PARAMETER

       group  - C group handle

RETURN VALUE

       f_handle
	      - Fortran group handle

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       This function does not return the normal MPI_SUCCESS integer value upon success.  Instead, it returns a handle to the converted object.	If
       an error occurs, the appropriate NULL handle will be returned.

MORE INFORMATION

       For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1  and  MPI-2	standards.   These
       documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
