Unfortunately only one box to check to cover all betas. Should change when these go main stream. Patience grasshopper.

rhetorical question - Which one of these WUs is a CPU or GPU that was processed on the same device?

BETA_ X0000132761497201202241058_ 0-- 644 Valid 3/16/12 06:18:10 3/16/12 18:14:37 1.40
BETA_ X0000130860197201112120941_ 3-- 644 Too Late 3/17/12 00:02:01 3/17/12 00:21:56 0.30

Without knowing the significance of the batch number or looking at the contents of the WU package for hints of word GPU, CPU, or opencl, the only reasonable way to know which is a CPU or GPU is by the completion time. Maybe in the future the WU task name will include some GPU designation to answer your simple question. Or did you have another simple question?

Edit:

Found this post by armstrdj:

For those seeing high CPU time can you verify that you are not running a cpu workunit. This can be verified by looking at the tasks tab on the advanced view of the BOINC client. If the task is GPU it will have either ATI or NVIDIA in parenthesis after the task name. The GPU version will use cpu at the start for a bit to do some initial things but it should start to use GPU only once the % complete begins to increment.

Thanks,

Beta testing isn't for everyone. :)

@Movieman: Sorry you're feeling the way you seem to be about the non-GPU-HCC betas. Like undersized fish, throw them back into the pond and they'll be eagerly snapped up by the hungry badge-hunting sharks.
The boxes on our My Grid >> Beta Testing page just allow beta testing on devices with the profiles that you nominate; there's no option to select only certain projects. You ticked the boxes ...

The HCC GPU betas may have been released prematurely because the HCC scientists decided to present the project at a conference in late 2011, expecting crunching to be underway by the time the Proceedings of the conference would be published. See: WCG Resarch >> Help Conquer Cancer >> Help Conquer Cancer status report: The main publication from WCG work:
Kotseruba, Y., Cumbaa, C. A., Jurisica, I. High-throughput protein crystallization on the World Community Grid and the GPU. J Physics: Conference Series, High Performance Computing Symposium (HPCS 2011: HPC in Medical Science), 2011. In press.
And they decided to publish a paper on it that has only recently appeared: The Help Conquer Cancer Project Publishes Paper in Journal of Physics . Because of the lead time for publication, they'd have submitted it to the Journal months ago. Then when the paper came out, they had to have some WUs out there, didn't they?
KNReed plus the HCC programmers are probably bald men by now, having pulled all their hair out trying to fix the bugs.

I'm sure the next batch of beta WUs will come along when and only when the techs have something new to test.

I think the HCC and WCG people are rather brave for undertaking this GPU project using such a recent and immature technology as openCL, and I hope they are getting support from the openCL community and GPU manufacturers.

The check boxes to receive REGULAR work units is TOTALLY different than the check box to receive Beta units, they ARE NOT related!! If you have the check box checked to receive Beta units, you will get them even if NONE of the boxes above it are checked!! As stated there is currently only ONE check box for the Beta units though, not a project by project one. So it is an all or nothing thing, at least for right now. LOTS of things are 'in the works', but I do not know if that is one of them or not. One of the things that I DO know about will be the ability to check to receive cpu OR gpu units, or both or even neither, when the project goes 'live'.
