2.5Pflops CPU + GPU machine
 
According to [URL]http://www.bbc.co.uk/news/technology-11644252[/URL] the current fastest supercomputer has a performance of 2.5 Pflops and gains a significant amount of its power from nVidia gpus.

I wonder if the users are programming in CUDA.

[QUOTE=http://en.wikipedia.org/wiki/Supercomputer]As of October 2010 the fastest supercomputer in the world is the Tianhe-1A system at National University of Defense Technology with more than 21000 computers, it boasts a speed of 2.507 petaflops, over 30% faster than the world's next fastest computer, the Cray XT5 "Jaguar".[/QUOTE]

Probably yes and no. With the release of CURAND, CUFFT, CUBLAS, CUSPARSE, and CULA, a lot of compute intensive code, even that requiring a good random number generator, using the standard FFTW, BLAS, or LAPACK libraries can be ported to CUDA with minimal changes.
