I am interested in the performance of parallel machines. A few years ago I used a 2D FFT benchmark to study VM performance. I'd like to get this program again, do you have such a thing? I used the 2D FFT program while working for a work station manufacturer on their UNIX kernel. They got the program from a prospective client, the NBS (National Bureau of Standards) in Colorado. Also, I am looking for performance numbers for 2-D mesh-router machines, like the one Intel is building for Cal Tech, and for numbers on Hypercube machines. I am interested in how quickly they do: 1. matrix transpose 2. matrix multiplication 3. 2-D FFT (which probably uses matrix transpose if the matrix does not fit in physical memory) 4. bit reversal (i.e., reversal of a huge bit vector spread over all the memories) 5. any other benchmark by which such machines are measured or which are especially inefficient on these machines Any pointers, numbers, or code will be greatly appreciated.
