There's some compiler interaction with the code which no-one has yet 
dug into that makes icc compilation of Radiance fail for some 
compilation settings.  For the moment, stick with gcc.

Depends on the cluster.  I suspect not much, though; the program 
binaries are going to be cached in RAM in the nodes.
