Topic 84807

So this project sent me 40 tasks for the ATI, all scheduled to run for ~28 minutes, however they all run for 6 seconds and err. I have tried the obligatory exit & restart of BOINC already and I just did a reboot to make sure it cleared the video RAM. Doesn't matter.

Example task: http://albertathome.org/task/86788

[pre]7.0.7

I've set the project to NNT for the time being.

And a next 44 tasks blown to

And a next 44 tasks blown to the wind. Which is weird in itself, since when I checked earlier today, BOINC could get 2 tasks maximum per day. How can it have gotten 44 then?

Really on NNT now. I see that all of them err on other ATIOpenCL computers as well, but not necessarily on CUDA. Like http://albertathome.org/workunit/30375.
