mpireconfig, a way to create Makefiles

Much of MPICH's portability is handled throught the careful construction of system-dependant Makefiles by the configure program. This is fine for installing MPICH, but what can you do when you are building a new application? For simple applications, the mpicc and mpif77 commands may be the simplest way to build a new application. For more complex codes, we recommend taking a sample Makefile.in file, for example, in mpich/examples/test/pt2pt. Modify those parts that are are relavent, such as the EXECS and specific program targets. To create a Makefile, just execute

    mpireconfig Makefile 

(mpireconfig is in the same directory as mpirun). This generates a new Makefile from Makefile.in, with the correct parameters for the MPICH that was installed.
