LAM/MPI Parallel processing

[Simon Valiquette <Simon.Valiquette@example.com>]

Hi everybody.

  I'm building a simulator, which seems to work fine so far except that
it is too slow.  Since the algorithms themself cannot be significantly
more optimized, I decided with my boss to make a version that will work
on a Beowulf.

  I found out that LAM/MPI would probably be a very good mix of
efficiency and portability (the Beowulf I am building is a mix of PC,
DEC Alpha and Sun computers).

  There is a lot of documentation about using or setting up LAM/MPI, and
I find the library very easy to use.  But there is not so much good
documentation about how to make a good and efficient design for parallel
programs.  I already have some idea about how to make my simulator
working efficiently in parallel, but I'm sure that a book would be able
to give me many tips and making me saving time.

  So, I would really appreciate if someone can suggest me some good
books about designing efficient programs on a heterogeneous cluster of
computer.  I don't mind if the book use Fortran, C or any other commonly
used language (personnaly, I'm using C++), as long it help me making a
more efficient simulator, considering the available hardware.

    By the way, the structure using a master that just dispatch jobs to
slave computers are not suitable for me, because each nodes have to
communicate with some others nodes, and that the amount of data is too
big (say, easilly over one GB for a single simulation).

  Thank you in advance,

Simon Valiquette


PS:   My boss is really amazed that I can produce better quality
software using only free GPL softwares, than in using for over 1000$ in
softwares running under the other OS.
