SDK issues with GTX480

Hi,
we just bought a GTX480 and start to test the board. Almost all SDK examples are working unless:

  1. radixsort, but i supposed this is due to the cudpp call inside the radix sort
  2. bandwithTest hangs
  3. deviceQuery hangs but deviceQueryDrv works, same behavior with matrixMul

It’s very strange. Have you some clue ?

Alexis.

Actually not related with the GTX480. I installed Cuda 3.0 with Ubuntu 10.04 and got the same result with a GT220 card …

SOLVED

Silly problem: in installed the SDK in /usr/local and some examples are writing files and did not show any errors and any screen output in case of problem when creating the file. So when those examples are not launched by root they simply hang.
