MPI allows you to have your source code in any directory.
For convenience, you should probably put them in subdirectories under
~yourusername/mpi.
To compile your source code, you should first copy the
makefile in
Appendix A available as
~pollock/public/Makefile on porsche into the
directory of your source code.
This makefile will compile the sample programs, the hello world and
Mandelbrot Renderer, and
place the executables in the current directory.
(It also shows how to compile another program that is NOT given to you.
This is just to demonstrate different parts of a Makefile.)
To compile your own programs, you will find it easiest to simply
change the names in the Makefile.
As you can see from the Makefile, you can compile simple C programs that call MPI routines with:
mpicc -o program_name program_name.c -lm(where -lm links in the math library)
For simple C programs that use MPE graphics, you can compile with:
mpicc -o program_name program_name.c -lmpe -lX11 -lm
Fortran compilation is performed similarly; exchange mpif77 for mpicc and program_name.f for program_name.c. Type man mpicc or man mpif77 for additional information.
