mpif90(1)
NAME
- mpif90 - Compiles and links MPI programs written in For
- tran 90
DESCRIPTION
- This command can be used to compile and link MPI programs
- written in Fortran 90. It provides the options and any special
- libraries that are needed to compile and link MPI programs.
- This command is still under development, as is support in
- MPICH for Fortran 90.
- It is important to use this command (or a Makefile pro
- cessed with mpireconfig ) particularly when linking programs, as
- it provides the necessary libraries. It can also simplify the
- use of the MPE profiling libraries, through the use of the
- -mpilog , -mpitrace , and -mpianim commands.
COMMAND LINE ARGUMENTS
- -mpilog
- - Build version that generate MPE log files
- -mpitrace
- - Build version that generates traces
- -mpianim
- - Build version that generates real-time animation
- -show - Show the commands that would be used without
- runnning them
-help - Give short help
-echo - Show exactly what this program is doing. This - option should normally not be used.
others - are passed to the compiler or linker. For exam - ple, -c causes files to be compiled, -g selects compilation with
- debugging on most systems, and -o name causes linking with the
- output executable given the name name .
ENVIRONMENT VARIABLES
- The environment variables MPICH_F90 and MPICH_F90LINKER
- may be used to select different Fortran compiler and linker.
- Note that since MPICH is built with a particular C and Fortran
- compiler, change the compilers used can cause problems. Use this
- only if you could intermix code compiled with the different com
- pilers.
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
is a convenient way to build simple programs.
