Faster Faster Faster
Our machines, even when hitting an apparent performance peak, only run at one small fraction of their true potential speed. I feel that today's computers and their software are OK for routine spectra. I couldn't ask for more. Other spectra are quite large, however, and I must wait a few seconds during processing. Without going into the third dimension, consider these novel experiments to measure long range heteronuclear Js. Each row contains at least 4096 points. Quite likely we are going to see larger rows in the next few years. The time required to compute the FFT is in the order of the seconds. It would be great if we could half this time. The solution is public since 2008 and freely available. It must also be well-know, because I have initially found it on Wikipedia . What they say, in practice, is that if you use the GPU (the graphic chip) instead of the CPU (the main brain of the computer)... In this work we present a novel implementation of FFT on GeForce 8800GTX that ...
