Hallo!
Can become versions for GPU identified by name?

Kind regards
Martin

Oh, sorry. Yes : the 1.05 !!!

Hallo Steffen!
Thank you for your response.
... but caused by the graphics card interfering with your regular display and is not a defect by albert@home from what I grasp.

This task was running on a GTX550Ti with 1 GB of RAM in slot 0. At the same time a task of BRP4 from EaH was running on the same card - 0,5 mode -. So you are probably right. I didn´t check for the memory load of the GPU, as in EaH I can easily run 3 task a time. I don´t know, how much of memory the OpenCl task does require. The probably too high memory load might also the reason for the long run time. I will take attention on that next time.

Thank you for this hint.
Kind regards
martin

I´m new here since yesterday afternoon.
The change from BOINC 7.0.25 to .26 was straight forward, except that it took astonishing long - some minutes ? - until my established tasks became running once again.
To establish AaH in my BOINC was more complicated, as AaH is not included in the list of projects in BOINC Manager/Tools/Add a project or project manager. I´d help me by clicking on EaH and replacing in the URL Einstein by Albert. It took a while to find this way. Why isn´t AaH included in the list of projects ??? In the AaH preferences I set the GPU utilization factor to 0.5, BRP4 check and S6LV1 unchecked.
I was somewhat astonished to find in the task log AaH running (1 CPU + 0.5 NVIDIA GPU) and 1 CPU waiting to run S6LV1. Whereas BRP4 tasks from EaH are running with (0.2 CPU + 0.5 NVIDIA GPU) and all 4 CPUs crunching S6LV1 tasks. The CPU load was reduced to about 90%, where as I had before always 100% of load. During running AaH the desktop was very sticky, most time I had to wait some seconds before any activity could be performed. This was also during the phases of waiting of the AaH task. The desktop was no longer sticky when the AaH project was suspended. This is a very uncomfortable way of operation.
So it was running quite a while, but about 15 minutes before the AaH task came to end, I found, that within the last nearly exact 20 minutes interval 3 of the running BRP4 tasks from EaH became marked as "Error while computing", all with Exit code 1002. The AaH task it self ended fine. To morning it was validated by a ATI card running under Linux on a Intel CPU. The running time is about a factor 3 longer, where as the CPU time is comparable - AaH/EaH -.

Because of the divers reported malfunctioning I supended AaH. It´s nice that the task became validated, especialy as the counterpart was of much other type. It shows, you are on a very good way, and when the next version will be available, I will try again.

Kind regards
Martin
