[nfbcs] Possible Computer Science Speaking Topics

[John G. Heim]

About science & linux... If there is a supercomputer in the world not 
running linux, I've never heard of it.  I manage high performance 
computing for the Math Department at the University of Wisconsin but we 
don't do like real supercomputing. Right now our biggest cluster is just 
108 cores. Even so, from what I've seen, everybody who does scientific 
computing runs linux.
