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.
This blog is to chronicle my attempts to climb up the BOINC credit ladder with almost no hardware budget.

DNETC & CUDA on x64 Ubuntu ... update
Following on from my last post, I tried a few ideas to try and get the CUDA client working and after reading a few forum posts, realized that the problem was simply that my drivers were out of date and didn't support the cuda3.1 workunits.
I have upgraded to the beta 10.10 of Ubuntu and everything has worked straight out of the box. The BOINC client and the nVidia drivers that come with the distro appear to be fine for DNETC.
As a side note, I am pretty impressed with the Ubuntu 10.10 Maverick Meerkat release so far!
