GPU compute on C-70 APU?

VirtualLarry

No Lifer
Is it possible? Worthwhile?

I had to bust out some Alpine USB Pro Coolers, to cool my NanoPC AT-5570 units (C-70 APUs). With the fan blowing into the ventilation ports right next to the APU, temps dropped from 92C to 65C.

So now, I'm wondering, can I do DC on these little boxes, without significant additional power usage?

My Kabini-based E1-2500 AIO PC can do Einstein@Home WUs in 24hrs.

I don't know what kind of GPU that they use in the C-70. It's the same, I think (maybe?) as the E-350 chips, although I think that C-60 and E-350 are both Brazos, and C-70 is Brazos 2.0.

I'm guessing, VLIW4?

Can that run OpenCL WUs for any particular project? I think that the 68xx series of discrete cards was VLIW4 too.

I think that my HD4850 is VLIW5, which is good for MW@Home.

Let me install BOINC, and I'll see if I can pull any WUs for MW@Home. Wish me luck!

Edit: Whoops, didn't work. Forgot, MW@H requires double-precision. Guess this APU doesn't have that.
Maybe I'll see if Correlizer has any WUs.

Edit: Correlizer project URL isn't resolving to a BOINC project anymore in the client. Guess that's over.
Time to try WCG.

Edit: Well, WCG is going to be slow-going, but it's working. I left CPU usage in BOINC at 60%, so I'm getting a jagged sawtooth in the CPU usage graph in Task Manager, but I'm not seeing any real temp increase either, so that's good.

Edit: Added PrimeGrid, that might have been a mistake. It downloaded a Genefer 3.0 (atiGFN) WU, and promptly gave me "Computational Error".

Does anyone know where to obtain the ATI 13.12 "Mobility" Cats? When I went to download drivers at AMD.com, they offered 14.4, but didn't have a link to click for "previous drivers" anymore.
