My fault it is referred to as compute capability 1.3, which is hardware specific and only the GT200 series of GPUs support it. Also, I'm in the process of updating the application to support the progress bar, check pointing will not be supported.

The CUDA application for 32 bit Windows has been deployed on BOINC. In terms of hardware a NVIDIA GPU supporting CUDA 1.3 is required. The following GPUs: GeForce GTX 295, 285, 280, 260, Tesla S1070, C1060, Quadro Plex 2200 D2, Quadro FX 5800, 4800 are known to have CUDA 1.3 support. The GPUs also need to have 256 MB of Video RAM

Um..the 8800GT 512 meets that.

Nice!
Will there also be a 64bit Windows CUDA application?

I'm having difficulties building 64bit Windows applications with Visual C++ Express Edition so there will only be a 32 bit application in the beginning.

With the server upgrade now in place work has begun on setting up the server to be able to distribute the CUDA client to users that have access to a CUDA 1.3 card (one that supports double precision). Right now a Linux/GNU 64 Bit CUDA application is live, however, there are some issues with the NVIDIA drivers and BOINC so the application seg faults. This issue should be non-existant on Windows, therefore, over the next few days a Windows 32 bit CUDA client will be added to the server.

...will go away as they got the server straitened out.

Until a gazillion new hosts attach here running CUDA. ;)

CUDA 1.3 is required for Double Precision support, single precision was tried, however, it only gave accuracy to 6/7 decimal places which is not enough.
