PAPI: Inventor and original author. This R & D 100 Award (2001) winning project allows the gathering of detailed performance measurements from inside many components of modern computer systems, including the network, the GPU, power supplies and of course the microprocessors. I first had the idea in the spring of 1995 which means PAPI is almost 20 years old and still going strong
