On compilation of the CUDA SDK, I’m getting a nvcc fatal : Unsupported gpu architecture ‘compute_20’ My toolkit is 2.3 and on a shared system (i.e cant really upgrade) and the driver version is also 2.3, running on 4 Tesla C1060s
If it helps, the problem is being called in radixsort.
It appears that a few people online have had this problem but i havent found anywhere that actually gives a solution.
I believe compute_20 is targeting Fermi hardware, which you do not have. Also, Cuda 2.3 doesn’t support Fermi features or compute_20. Try using compute_13 instead.
