First CUDA App for Linux available for Beta Test

(moderation:
The first Einstein@home CUDA App for Linux is available for Beta Test at Beta Test Page.
This is a big package to download (26MB), as it contains both applications (S5R5 and ABP1).
We are still new to writing app_info.xml files for CUDA applications. The one contained in this package should allow to run one ABP1 task per CUDA device, occupying a full CPU core for support, and run S5R5 tasks on the remaining CPU cores.
There are no entries for older than the latest App versions 1.06 / 1.07 in the app_info.xml, tasks already assigned to older Apps will error out.
The ABP1 CUDA App has undergone limited testing with a BOINC CC 6.6.36 and a 181.20 NVidia Driver on a Debian Lenny x86 system. We can confirm that the App doesn't crash immediately on such a setup, but not much more. We already ran into some mysteries of the CC scheduler, though.
Again, this is our very first experience with CUDA Applications, please bear with us and don't expect everything to work right away.
Please test and report, and please include important information (like the NVIdia Driver and Core Client version) in your posts.

I think so - it's running on such a machine here.

I observed the same crashes in libcuda until I switched back to the old driver that's recommended for CUDA 2.1 (Driver version 181.20); I'm not sure about the version of the driver that crashed.
Would you mind trying the old driver just for a test?

We posted a new CUDA App for Linux that fixes a bug and should be a little faster on the CPU, too. See here.
