Einstein@Home GPU/APU Application for AMD/ATI Graphics Cards: discussion thread

@Gaurav: What does the Client say about the GPU (in stdoutdae.txt or in the event log of the manager)? Does it say somehting about OpenCL caabiities?

Is the host attached to Albert, too? If so, what is its hostid (possibly send PM)?

Oliver,

Installed 12.4a without requiring mod, recognized as Mobility 5800 series.

Upon WU startup encountered driver restarts at ~0.038%.
GPU-Z 0.6.2 shows a quick uptick of dedicated memory usage then flat-lined (even though the WU ran for another 10secs before suspension).

Updating to latest driver doesn't work.
Any other ideas?

EDIT: POEM++ OpenCL WUs are now running ~15mins faster! :)

EDIT2: Scratch that - it's ~29mins (!!!) faster.

Yep, that's the (32Bit) App.

It looks like the Client doesn't find the (64Bit) libs.

Could you try the 32Bit version of the Client?

The BOINC server is currently down and will be for a while.

Here is our local copy of BOINC 7.0.28 for Windows, built by Rom today:

* boinc_7.0.28_windows_x86_64.exe
* boinc_7.0.28_windows_intelx86.exe

wow, bummer...

thanks for the heads-up Richard...i was wondering what was going on w/ SETI too...
