- The table is clearly mistaken, because in the previous table, it is clear
- that each processor is capable of 2 floating point operations per clock,
- and there are a maximum of 1088 processors at 20 MHz. 32 processors would
- give a peak of 1.28 GFLOPS. So, the listed 513 GFLOPS is clearly an
- error. 513 MFLOPS would be consistent, although I don't know if it is
- correct.
