Excuse me, how did you measure 100 trillion calculations per second?
What is the unit of calculation? Integer addition, multiplication?
Evaluating an activation function?

I suspect it is less than the computing power of a 10^4 node
supercomputer, but it may well exceed the computing power of 10 to 100
processors. With regards to memory, I think it may be at the order of
a petabyte or more. (These figures from what I remember of a
back-of-the-envelope calculation, so don't expect them to be wildly
accurate :) )
