Beowulf Questions

[Randall Jouett]

Howdy,


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....

Best Regards,

Randall
