Here at Luddite.net, we used to work on a variety of theoretical nuclear physics problems that include non-relativistic scattering theory for protons and pions and the structure of light nuclei and stretched high spin states. Having completed that, we are currently working on the following:

• One cpu seems to be stuck in an infinite do loop

  If anyone know how to fix this, please let us know. (Its not like you can just hit ctrl-alt-del on one of these Crays)

  20 print x
  30 x=x+1
  40 goto 20

• Calculating infinity (see above) 

• Teaching Linux to underacheiving youths in the slums of Fairfax
