[I'm just sitting here waiting on a Cray...]

Before taking this job I, like many, had an aura of mystery around
Crays [those friends at lll-crg, lanl, hao, and other Cray sites
can pardon me for a sec].  Just for those without: I am working with a
fluid dynamics code which under our test conditions runs 0.27 cray seconds
including I/O.  The code is vectorized.  By turning on subscript range
checking (and turning off vectorization by default), the code now takes
over 60 cray seconds to run.  I wonder how much I spent?
