title: NVIDIA CUDA SDK Examples Compilation Unsupported Architecture 'compute_20'
body: <p>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</p>
  
  <p>If it helps, the problem is being called in radixsort.</p>
  
  <p>It appears that a few people online have had this problem but i havent found anywhere that actually gives a solution.</p>
