cudaOpenMP ? only one thread with 2 GPU's?

Accelerated Computing CUDA CUDA Programming and Performance
1

When I run cudaOpenMP I get the following result

number of host CPUs: 8
number of CUDA devices: 2
0: GeForce GTX 280
1: GeForce GTX 280

CPU thread 0 (of 1) uses CUDA device 0

PASSED

Press ENTER to exit…

As far as I can see in the code it’s supposed to spawn one thread on CPU for each GPU in the system. It detects 2, but spawns only one.
Am I missing something?

Edit: with the following fun factor. It recompiles cutil64, and after that my own program won’t start. have to look into this
