Default 2.5Pflops CPU + GPU machine

According to http://www.bbc.co.uk/news/technology-11644252 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.

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.
