| 9 | ! !MODULE: m_mpif - a portable interface to the MPI "mpif.h" COMMONs. |
|---|
| 10 | ! |
|---|
| 11 | ! !DESCRIPTION: |
|---|
| 12 | ! |
|---|
| 13 | ! The purpose of \verb"m_mpif" module is to provide a portable |
|---|
| 14 | ! interface of \verb"mpif.h" with different MPI implementation. |
|---|
| 15 | ! By combining module \verb"m_mpif" and \verb"m_mpif90", it may be |
|---|
| 16 | ! possible to build a Fortran 90 MPI binding module graduately. |
|---|
| 17 | ! |
|---|
| 18 | ! Although it is possible to use \verb'include "mpif.h"' directly |
|---|
| 19 | ! in individual modules, it has several problems: |
|---|
| 20 | ! \begin{itemize} |
|---|
| 21 | ! \item It may conflict with either the source code of a {\sl fixed} |
|---|
| 22 | ! format or the code of a {\sl free} format; |
|---|
| 23 | ! \item It does not provide the protection and the safety of using |
|---|
| 24 | ! these variables as what a \verb"MODULE" would provide. |
|---|
| 25 | ! \end{itemize} |
|---|
| 26 | ! |
|---|
| 27 | ! More information may be found in the module \verb"m_mpif90". |
