Oh yes, forgot about that. You'll also need a cuda 2.2 compatible nvidia driver. Get it in http://www.nvidia.com/object/linux_display_amd64_185.18.14.html

Any noticeable speedup?

There is a small one.

Tye:
Will it work with the new 190 driver and CUDA 2.3?

With the 185 driver and 2.2 libraries, I tried the 2.2 VLARkill app and putting the libraries in /usr/lib, the boinc folder, the proj*/setiat* folder, and my ~/bin but I kept getting computation errors with the 2.2 VLARkill app.  Argh.

I couldn't download the tools since they are now offering the 2.3 tools, hence the 2.3 question...

Tye:
BTW, this is the error info that shows up with such a workunit:

<core_client_version>6.6.11</core_client_version>
