Timing - compare 2GPU with 1GPU for the same case

```
What version of the product are you using? On what operating system?

Opencurrent 1.1.0 on Ubuntu 10.10

Please provide any additional information below.

I am trying to put timing statements into the code to compare the performance
of a single GPU and a 2GPU solution for the same case. I can't seem to get
anything to print out. In which function is the choice made whether to solve on
1 or 2 GPUs? I don't mind which test case is used in the first instance.

Is there by any chance an existing test script for this?

Thanks
Matt
