Have you characterized the differences between gnu and intel -

I guess i wont be much help tonight (maybe tomw i'll download the
new cuda stuff):

/usr/local/cuda-2.3/cuda/bin/nvcc -use_fast_math -O3 -gencode arch=compute_13,code=sm_13 -gencode arch=compute_20,code=sm_20 -DCUDA -I/usr/local/cuda-2.3/cuda/include -c
nvcc fatal : Unsupported gpu architecture 'compute_20'
