G'Day !
This is what I wrote to someone on a different mail list, but is relevent
to your question ....
The best sources of information is of course the net. I would start with
the HOWTOs. The following give a good general knowledge of the subject.
1) Beowulf-HOWTO
2) Parallel-Processing-HOWTO
3) SMP-HOWTO
The NFS-HOWTO and the NIS-HOWTO are also very useful.
In a Beowulf cluster, parallel processing is done by message passing,
instead of shared memory in a SMP (symetric multi-processing) systems. The
2 most popular message passing systems are PVM \
(http://www.epm.ornl.gov/pvm/pvm_home.html) and MIPS \
(http://www-unix.mcs.anl.gov/mpi/). PVM is older so the code base is larger. MIPS \
until recently, was forked into several competing versions, and much newer. Most \
observers believe MIPS will eventually replace PVM as the defacto standard, as a new \
standard has been written. Porting of PVM code to MIPS is also reportedly
trivial.
My code is in the planning/design stage currently. My 3D modeler is
currently being coded, but is taking significantly longer than
anticipated. I am also currently obtaining new hardware to build a new 5
node cluster. So my parallel code ....
Here is some advice I got from the GTK+ mailing list:
Dani Mezher:
"I did the same to build the frontend of an MPI parallel code. The
frontend I built is a stand alone process that uses a TCP/IP socket to
connect to
the server node; this works just fine."
Slyder:
"Well, I'd keep it a modular system. Have a piece that handles the input
(modelling, and a piece that does the PVM [CFD/FE/FDTD/etc] processing.
Mayvbe a thread to handle execution of the solver. I'm actually working
on something similar, though I'm about to do a rewrite, so my code may
or may not be of much use..."
Hope this helps.
cheers,
Jim Parker

Subject: Cluster Applications
Hi all,
I am new to the concept of clusters but I have been
doing a lot of reading recently because I would like
to get some experience with clusters...my question is
what are or were can I find information on some (free)
applications that I can run on a beowulf cluster. I
would not be setting up anything to fancy at first
maybe a 2 or 4 node cluster but I have no idea what I
could run on this cluster. Thanks for the help.
Shain
