As mentioned in my last post, I upgraded to the beta of Ubuntu 10.10 and in the process, the default drivers now support CUDA 3. I realized that the CUDA 2 application that I had copied across from the previous version of Ubuntu was crashing workunits with "directory not found" errors, so downloaded the CUDA 3.1 app from the "Power (Optimized) Applications" section of the Collatz website. I uncompressed the downloaded file, dumped the contents in the relevant directories and all is working fine! This stuff is getting really easy to use these days!
In terms of credit, the Collatz app produces almost the same credit/hour that the DNETC CUDA3 app does. I'm not sure but I think the new Collatz application is running the GP harder as I see the average temperature is now 70'C. I will watch that for a day or two and confirm the theory.
