NAME

mpif90 - Compile and links MPI programs written in FORTRAN 90

SYNOPSIS


mpif90 [option | filename]...

DESCRIPTION

The mpif90 command compiles source files in the FORTRAN 90 language, and links object files. The source filename extension should be .f, .F, .f90, .for or .FOR.

OPTIONS

-compiler compiler

--compiler compiler

Specify the Fortran compiling environment used to compile and link MPI programs. For more detail, please read Providing Optional Compilers.

-compiler-path compiler

--compiler-path compiler

Specify the Fortran compiler. This option will override the compiler used for the compiling environment. NOTE: No check is made that compiler is compatible with the MPI libraries

-mpi mpi_version

--mpi mpi_version

Use the MPI version specified with mpi_version. The command will abort with an error message if the MPI version cannot be found. Currently, supported MPI version are mpich-1.2.4 and mpich-1.2.0. default is mpich-1.2.4. REVISED

-device mpi_device

--device mpi_device

Use the MPI device specified with mpi_device. The command will abort with an error message if the MPI device cannot be found. This version dose not use in this version.

-show

Show the commands that would be used without running them

-nockpt

--nocheckpoint

Disables all checkpointing facilities. Also disable all system call overrides for checkpoint.

-help

Display simple usage

EXAMPLES

To compile a single file foo.f use:

	mpif90 -c foo.f

To link the output and make an executable, use:

	mpif90 -o foo foo.o

Combining compilation and linking in a single command:

	mpif90 -o foo foo.f

Although this is a convenient way to build simple programs, it may not work on some systems, and thus is not recommended.

Combining a compilation environment with a specific compiler:

	mpif90 -compiler fujitsu -compiler /usr/tool/FFC/bin/f90
