MPI-Beowulf configuration question: where does Makefile @XXX_XXX@ notation come from?

[Chris Richard Adams]

Hi-

I have installed the full 27Bz-7 release and have a four node cluster
running.  I succeeded in getting the mandelbrot demo running. very cool.

Now I'm learning more about MPI and am working with the examples in
/usr/mpi-beowulf/examples dir.

Q1.) I get error messages during 'make' stating 'command MPI_CC@ not
found'.  I assume it wants mpiCC from the bin directory - but how does
@MPI_CC@ link to that binary?  How do I resolve the other @xxx_xxx@
references?

Q2.) Is there any documentation available for these samples? Any
documentation on MPI calls using mpi-beowulf? 

Q3.) Is there any documentation for the binaries in
/usr/mpi-beowulf/bin?

Q4.) What is the difference between the /examples and /mpe_examples?
What does mpe mean?

Thanks,
Chris
