Consistent RayleighTest failure ("unspecified launch failure")

```
When running the RayleighTest unit test I encounter a consistent
"unspecified launch failure". This error is observed for both release and
debug versions.

What steps will reproduce the problem?
1. Run the RayleighTest unit test ( ./utest -gpu 0 RayleighTest ) Failure
observed for the "run resolution 32" case. See rt_output.txt for sample
output.

What version of the product are you using? On what operating system?
Running current release version available via hg clone.

Running on CentOS 5.4 x86-64 system (uname -a):

Linux manzano 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64
x86_64 x86_64 GNU/Linux

Using GeForce GTX 260 MaxCore device (216 cores / 27 multiprocessors). See
dq_output.txt for more details.

Inizia eseguendo `./utest -gpu 0 RayleighTest`, concentrandoti sul caso non riuscito “run resolution 32”. Confronta il fallimento con le diagnosi allegate `rt_output.txt` e `dq_output.txt`; il lavoro è completato quando RayleighTest supera il test sulla configurazione GTX 260 indicata, sia nelle build release sia in quelle debug.
