NAME

mpiCC - Compiles and links MPI programs written in C++

DESCRIPTION

This command can be used to compile and link MPI programs written in C++. It provides the options and any special libraries that are needed to compile and link MPI programs.

It is important to use this command (or a Makefile processed 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.

mpiCC cannot be used to compile C programs. Use mpicc for C programs.

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 example, -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_CCC and MPICH_CCLINKER may be used to select different C++ compiler and linker. Note that since MPICH is built with a particular C++ and C compiler, change the compilers used can cause problems. Use this only if you could intermix code compiled with the different compilers.

EXAMPLES

To compile a single file foo.c , use
 mpicc -c foo.c 
 

To link the output and make an executable, use

 mpicc -o foo foo.o
 

Combining compilation and linking in a single command

 mpicc -o foo foo.c
 

is a convenient way to build simple programs.
