Debian Powers 512 Node Cluster into Book of Records
December 11, 1998
------------------------------------------------------------------------

>> News

Over 512 computers were assembled for the CLOWN (CLuster Of Working Nodes) 
system that ran on the night of December 5-6.  This cluster used a modified 
version of the Debian GNU/Linux distribution (reduced in size to a mere 16 
MB, and boot script modifications) to run a combination of PVM (Parallel 
Virtual Machine) and several application programs.  These programs included 
povray (a ray tracing program used to calculate frames for a film), Cactus, 
a program that solves the Einstein Equations, which are ten non-linear joint 
hyperbolic-elliptical partial differential equations.  These are used to 
describe Black Holes, Neutron Stars, etc. and are among the most complex in 
the field of mathematical Physics.
