Hi Randall and all
I have used PVMPOV for ray-tracing. It is the POV-Ray application with
a PVM patch applied to it. It works very well and the XPVM interface
allows all the processes and communications to be seen. It takes .pov
text files and converts them into .tga graphics files. My small cluster
of four 750MHz Athlons, does skyvase.pov in about 30 seconds. PVMPOV is
easy-ish to setup and configure and once its all done you have a nice
face rendering system.
This uses PVM3.4.3, POV-Ray v3.1 and the PVMPOV3-1g-1.
Other things like BEOLIN are Beowulf specific and don't require PVM to
be on each node. This addresses issues of external node access and
pipes ALL the processes via the frontend.

Please feel free to correct me if any of that is wrong, I kinda a newbie
myself. Doing a final year degree project on this stuff.

Subject: Beowulf Questions
Newbie alert, although I have ready the FAQ, visited a couple
of the project sites listed on beowulf.org, and even read a
HOWTO or 3 :^). Being a software engineer, I'll just say that
I'm way too familiar with RTFM and google searches :^).
Basically, I'm looking for the following info:
* Is there a beowulf setup out that that is used to
gernerate ray-traced graphics? If so, does anyone
have a links to sites that in-depth info?
* Is there a beowulf setup out there setup specifically
for random-number generation, with its main focus on
generating "truly random" numbers, if you can say that
synchronus, clock-based computers are capable of generating
truly random numbers :^). If so, has a cluser of this type been
used in encryption and decryption purposes.
* Is there a beowulf chess engine out there? If so, has it
ever played in the computer chess championship, and how
did it perform?
* Is anyone working on beowulf clustering based on trusted-host
computing? That is, instead of having a local cluster of
numerous computers in various racks, a person could say something
like, "I trust this host and that host, and if any of them want
to use my excess CPU time over the Internet, then they are welcome
to use my broadband-connected machine for their purposes. In other
words, this would be a setup much like the SETI screen blanker, yet
the screen blanker would be removed and out of the loop. Anyone doing
this? If not, I'm interested in giving this a shot. (Send e-mail or
post here, and I'll give a verbose explanation of the way I see
something like this working.)
* Is anyone using real-time versions of Unix(TM) in their beowulf
setup? If so, did they/you notice a significant increase in
processing speed? Personally,and off the top of my head, I'd
think the main bottleneck is the MPI and network communications.
[This next one will be a bit "out there," but what the hell -- no
guts no glory! :^) ]
* Is anybody working on a model that encompasses nano-technology?
That is, is there anyone out there working on algorithms that
would allow nano-bots to communicate and process information in
a beowulf-like manner?
Anywho, TIA, and feel free to answer any of the questions, even
if you can't answer them all. The way I see things, a bit of knowledge
gained is better than no knowledge at all....
