Hi,

We just released BRP4 v1.25 for ATI/AMD OpenCL under OSX for Intel Macs ("Lion" and above)

Notes:
* Known issue: no support for any OSX version older than "Lion"

* Please let us know how running the app is impacting the responsiveness of the Lion Desktop.

* Please use BOINC client (>=7.0.27) or later. Note that this BOINC version is still a development version (but fixes some OpenCL related problems), it can be downloaded from here:

http://boinc.berkeley.edu/download_all.php

Without updating to this BOINC version, you will not be able to get OpenCL work on Albert!

Let's try and collect your feedback to this specific release (and this one only) in this thread.


Thanks,
Heinz-Bernd

This machine used to get work, back before the mac app was discovered to have a problem. Now it cannot get work.

Also, why is it talking about CAL? Shouldn't this be opencl?

Thanks for the feedback. I need to check the plan class configuration, it's been a while since we last had the Mac app in the field .

Cheers

Hmmmm....this could be a BOINC client problem. We are keeping this app in it's current state to allow teh BOINC developers to study this. You will probably want to disable ATI/AMD tasks on Albert@Home for now to avoid getting more of those aborting tasks.

Stay tuned

OK, this seems to work in BOINC version 7.0.25, but this version had other issues with OpenCL unfortunately. Again, for debugging purposes, we now allow 7.0.25 BOINC clients to download atiOpenCL jobs for OSX Lion.

Stay tuned

We have changed things slightly (the plan class name, actually) so that now the Mac OpenCL app should work with 7.0.27...7.0.29 .

Feedback is welcome.

Thanks for testing

I just put a new version 1.26 on Albert for ATI/AMD OpenCL Intel OSX Lion, this one mainly has performance improvements.

If it behaves well over the weekend, we will make a full test release of 1.26 for OpenCL on all supported platforms next week.

Nice weekend to all,
HB

Update: Fixed some problem that crashed the app under Mountain Lion preview, not sure this fixes it, tho. So newest version is 1.27.

Hi Bikeman,

I am not receiving any WU's (the latest Boinc client on Mountain Lion) - did you run out of them?

Thanks,

branjo

No, there should be plenty of them left (they are replenished automagically).

Your PC is hidden, so can you give us some hints from the "Event Log" in Boinc Manager?

- IS BOINC actually asking Albert@Home for ATI jobs?
- IS BOINC detecting an OpenCL capable card (BOINC lists accelerators / GPUs when it starts up)

Thanks
HB

Today I got 2 of them :-)
