The CM-2 does 2,500 MIPS and 1,500 MIPS for 64-bit integer adds. Memory 
bandwidth is 300 Gbits/sec. When the new 4Mbit DRAMS are shipped it 
will max out to 8GB. The new C* and Fortran compilers on Sun 4 front-ends
should make using it not too bad compared to a Cray. Have you thought about
the CM-2? The references for this info are Parallel Supercomputing in 
SIMD architectures by R. Michael Hord (He mentions the SRC as a CM-2 64K site)
and TMC customer support group.

P.S. How's that for references Eugene?
