I assume one synapse firing represents one bit of
data. One floating point value = 32 bits nominally
for
scientific calculations. Therefore 10^17 bits/sec =
approx 3x10^15 Flops = 3000 Tflops. I personally
think bits/sec is a more fundamental unit of measure
than Flops, but computer power is often quoted in
Mflops, GFlops, and Tflops. It would be 3 Petaflops,
but peta- is not a commonly used metric prefix yet,
and I was converting into 'common' units for the
reader's benefit.
