Posted 4 Jan 2014 by piquadrat Post: In the meantime, I can offer three solutions for my problem: 1) Disable usage of GPU for BOINC projects. Senseless, all other Boinc projects (in my case Seti, Einstein) cannot use GPU either, although working properly. 2) Always cancel Astroid Cuda55 work units - you'll notice if one is computed by suddenly extreme slow mouse reactions. Tiresome, as you'll always have to press "cancel" if a Cuda55-WU starts. 3) My recommendation: uninstall newer NVIDIA-drivers and replace them by older versions. In my case, I uninstalled actual version 331.82 and re-installed the older version 314.22. Now everything's working properly again - Cuda42, Cuda50 - without slowing down my Computer for normal work. Seems as if now Asteroid-Cuda55-Wu's are not downloaded any more. Nevertheless, the GPU-computations Cuda42, Cuda50 are extremely fast - factor 5-10 faster than "normal" CPU-based computations.

Posted 2 Jan 2014 by piquadrat Post: Thanks for your answer - I wonder how the problem will be solved. Nevertheless, I'm surprised because the effect described above did NOT occur with the foregoing cuda45 wu's, and it is NOT occuring with all other GPU-appliances like Einstein-, Seti-GPU-wu's or movies using the GPU. The effect of extreme slow reactions occures ONLY with Boinc-Cuda55-Asteroid-wu's. Regards, Piquadrat |

Posted 1 Jan 2014 by piquadrat Post: High everybody, to get the new Cuda 55 working units, I updated my Nvidia Driver to the newest version 331.82. However, the results are very slow reaction times - for example, moving open windows on the screen is very slow, or pressing a button on the keyboards will sometime take some time until it works. If I disable the usage of the GPU by Boinc (what could NOT be the real sense of new wu's!) solves the problem immediately - everything's working normal. Any ideas? Utilities like Task Manager or Process Explorer show nothing conspicuous. Hard- /Software: I7-870 (first generation), Nvidia GeForce GT 440, Windows 7 Greetings, Piquadrat |
