virtual wolf

From: Ed King 
gee, it never occurred to me that I could build a beowulf cluster using virtual 
machines for the nodes.   obviously this configuration ain't gonna be a good 
test of cluster performance but the goal here is to experience building a 
cluster with more than just a few nodes (I already tried that and it was boring)

and surely I wouldn't install slave node vms on my 30 coworker machines while 
they weren't looking...

=============================================================== From: Jason Brown ------------------------------------------------------ I assume they are using windows: in that case, running headless VirtualBox would be useful. Just use 1/4 of their RAM and they may not notice. --Jason

=============================================================== From: Ed King ------------------------------------------------------ yes... they run Windoze. A few months ago I wrote a stupid-simple dotnet "app" that invokes qemu (and does other stuff, eg process monitoring) w/o popping up the vnc window... the dotnet app itself is visible but I should be able to turn off its visibility too. This could get fun, muhahahahahahaha...

=============================================================== From: Chad Smith ------------------------------------------------------ I don't understand the logic here exactly.... Doing x 10 times is boring... so maybe I should try doing it 100 times and see if it gets more exciting. ???? *- Chad W. Smith*

=============================================================== From: Ed King ------------------------------------------------------ imagine 1 teletype sitting idle until someone initiates a 2,000 line fortran program listing. music to the ears! but a single teletype is slow to print 2,000 lines. now imagine 100 teletypes sitting idle and someone initiates the same 2,000 line fortran program listing, but splits those 2,000 lines over 100 teletypes. what was once music to the ears is now a thunderous joyful noise, and it takes a fraction of the time to print the program listing, because it was divided up into smaller pieces. or something

=============================================================== From: Eric Wolf ------------------------------------------------------ Steve Ciarcia's Circuit Cellar column in Byte had plans for an ISA parallel processing card using 8xIntel 8051 CPUs. It used the built-in RS-232 in the 8051 for interprocess communication. I think you could even daisy-chain eight of them together for a 64-way setup! -Eric -=--=---=----=----=---=--=-=--=---=----=---=--=-=- Eric B. Wolf 720-334-7734
