No OpenCL included in Cat 12.4?

[VirtualLarry]

The download page for 12.4 mentions that OpenCL is included, and when I installed it, I installed the whole package, including the "APP SDK".

But GPU-Z is reporting no OpenCL support, and BOINC 7.0.28 and Einstein@Home are not showing any OpenCL WUs.

GPU-Z often fails to report OpenCL correctly. However the fact that your OpenCL applications aren't working is a bit more concerning. I'd suggest grabbing something easy to debug like LuxMark and seeing if that works, and then work from there. Cat 12.4 should definitely have installed an OpenCL driver.

Well, I'm done testing. Apparently, OpenCL is unsupported on the E-350 APU at this point.

Edit: Perhaps I'm wrong. I just read that Einstein@Home requires a Radeon 5000 or newer card to run OpenCL. I was hopeful I could run it on my APU (OpenCL is openCL, right? Except when it's not OpenCL).

I have two 6970s mining bitcoins via opencl on cats 12.4. Fresh install of windows, so it must be in 12.4 somewhere.

Are older stream apps compatible with the newest drivers?

Supposedly, OpenCL support on the 4000 series cards was "beta" or something. There are differences; for instance, you can return 8-bit ints on the 5000 series, but can't return anything smaller than 32 bits on the 4000 series.

If the PrimeGrid OpenCL app, for instance, works on your machine, then you have OpenCL. Einstein@Home might just need a newer card.

Hmm, I didn't realize that PrimeGrid supported OpenCL.

I enabled ATI/AMD GPU crunching under my PrimeGrid prefs, and checked off the sub-project that allows ATI GPUs.

I then updated, and I got two WUs. They ran on the ATI GPU.

However, both of them errored out with "Computation error", one after 6 seconds, one after 7 seconds.

Something similar was reported by APU users in a referenced Einstein@Home thread in the DC forum in my other thread about this issue.
