Interesting, thanks for the report. The one result that was reported shows that the app crashed somewhere in the drivers at it seems, maybe at the moment it was suspended??

It would be interesting to know whether other Mac users are seeing this as well or whether it was a fluke.

Hello all. Since the update

Hello all.
Since the update I have a AMD 12.8 boinc 7.0.28 and incompatibility with my graphics card HD 5450. In fact as soon as I run Boinc Manager, I immediately blue screen and shutdown. This was not the case with version 12.6.
Someone you have that problem ..??
I have a board version 12.6 ..??

For now and until the problem is solved, I have to work in safe mode with networking support.
With this solution, of course, I can not use the GPU.

I wonder if it takes one of modiffication boinc or wait for a change of AMD, or returned to the version 12.6 (I said with the old version, the problem of error in the color change appeared to be resolved, since my last GPU WU been validated as successful.)

You are running XP on both pc's.

As posted in an other thread, the latest amd driver version for XP that supports open-cl is 12.1
Another reason to avoid 12.8 is that crunching time increases signisficant.

I run einstein in the background & pause it when I need to do processor intensive work. I recently started getting WU's for the gpu but these won't pause when I need to do graphics intensive work. The Boinc manager tasks status is listed as suspended, but the task keeps on using the gpu. I had to abort the task to get on with work. Do you have any suggestions so that I won't have to continue to abort opencl-ati-lion tasks?

Same here, MacOS X 10.7 AMD Radeon HD 6750M 512 MB.

I'm sorry to have checked Einstein's "Won't get new tasks" due to sluggish GPU. :-(

using 12.1 driver still, i'm just a very special case:

This report is a little

This report is a little vague.
I've got an Imac with a Radeeon HD 6770M running Lion 10.7.4

I've had to turn off GPU processing because I noticed that playing flash video (you tube) while doing openCL processing had a tendency to hang the GPU.
The machine hangs hard (mouse pointer still moves but everything else is locked up) and has to be powered off.

Its not completely reproducable. It tends to happen after video has been playing for a couple of minutes. But has happened multiple times.

I assume its the openCL that causing it since it only started happening once the opencl work unit appeared. And its stopped since I unsubscribed from the openCL workunits. But its not a huge sample set.

Anyone else noticed issues?

You could try the option to

You could try the option to not "use GPU while machine is in use".
That way the the GPU tasks should only run when your machine is idle eg overnight.

Hi! Especially for

Hi!

Especially for notebooks, the GPU load can be quite nagging: slow down of the user interface, heat and fan noise. I really like that BOINC now has the option to selectively suspend the GPU in the "Activity" menu. So you can, for example, leave GPU suspended except when you really don't care (say at night). You will still get a lot more science done when using the GPU app during the night only compared to all-day CPU-only operation.

Hi! The app "Binary Radio

Hi! The app "Binary Radio Pulsar Search (Arecibo) v1.28 (opencl-ati)" crash on my laptop every time it started. I don't know how to get further detail (e.g. the log file of the app) in order to get this fixed. The OS is Windows 7 Home Basic, ATI driver version: 8.951.0.0 on ATI HD 7730M. And it seems that this laptop can choose which video card to use. There is another integrated Intel HD Graphics 4000. I'm to quite sure about that. What should I do?

Hi!

Is that the most recent driver available for that card? Updating the driver (usually) can't hurt.

Unfortunately the app isn't producing any meaningful diagnostic messages before it terminates.

Are you subscribed to other BOINC projects which offer OpenCL apps for ATI/AMD cards? I wonder whether this is a general problem with the OpenCL support on this particular host or it is specific to teh E@H app.
