The reason that people measure things in flops is that most of the
applications driving the development of massively parallel machines
are in the scientific/engineering arena, where flops are the goal.
For my own work, flops are also irrelevant.  Many of the processors
being used favor vectorizable floating point operations, including the
CM-5 and the new Meiko machine.  Last time I checked, these machines
can be ordered without vector units, but few people do.  For a machine
like the Intel Paragon or nCUBE-2, the correspondence between flops
and mips is pretty close anyway.

We recently turned ours off and boxed it up.  Too out of date, and too
quirky (SIMD, after all!).

Think in terms of what you could do with a machine with

 - 128 Gbytes RAM
 - 1 Terabyte disk
 - 300,000 MIPS

Such a machine is likely to appear in the next two years.
