Sorry, but Convex does not cite 32-bit MFLOPS since 32-bit floating point runs almost exactly the same speed as 64-bit floating point on C2 Series machines. For example, on the C240, the 1000x1000 LINPACK benchmark speed is 166 MFLOPS in 64-bit precision and 176 MFLOPS in 32-bit precision. ---------------------------------------------------------------------- Dave Dodson dodson@convex.COM Convex Computer Corporation Richardson, Texas (214) 497-4234
