Eunjin.Im, can you try the latest CUDPP 1.1.1 and see if it fixes your issue?  
It works 
for me on a Tesla C1060 on a similar Linux system.  I don't have a Quadro S4 
available.

Thanks,
Mark

I believe this is fixed by r110 which adds __launch_bounds__ (only in CUDA 3.0) 
to 
radix sort kernels.  I tested on x86_64 RHEL 5 with CUDA 3.0 and it was not 
working 
before this change, and working after it, so I assume it is fixed.

I will mark it fixed, and if Eunjim.Im reports that it is not fixed on his 
system, we 
can reopen.
