There are 3 BOINC projects I know which use CUDA, AQUA, SETI and MilkyWay, which also uses ATI boards. The results are mixed, to say the least, and on AQUA units run on CPUs are often faster, especially on multicore CPUs (AQUA is multithreading), than on CUDA GPUs. So I would advise the Einstein devs not to make available a CUDA version which is not foolproof. A Beta version could be acceptable.

GPUgrid is another project (also molecular simulations ), they go the oposite way and support only "exotic" platforms : CUDA and PS3.
It's been a well established practice here at E@H to have a beta-test phase before any fundamentally new apps are rolled out, and I think this is also the ONLY way to get it right: with so many different platforms and hardware variations out there "in the field", you can't test everything internally by the developers.
Good idea to have a beta project. At SETI they just released it to all and sundry and there was some confusion. Idem at AQUA.I do not have any graphic board, just a graphic GPU on my Linux box, which is a Radeon. But I am window shopping for a HD 4770, which is difficult to find. So no CUDA. Cheers.

Unfortunately Milkyway does not at present support CUDA based GPU crunching.
The only client uses the high end ATI cards (Radeon HD38xx & 48xx). This is because the project needs double precision done on the GPU, and ATI are the only cards that currently support this.
I do believe they project will eventually release a nVidia CUDA client, but, I think, this is a long way away ATM.

Einstein @ home will never get any real work done until
they create and release an ATI app.
ATI cards are much more powerful than nvidia in double
precision crunching.
But, they won’t (anytime soon anyway)__ Why? You might ask.
Nvidia__ (a shady company) _ has worked overtime to promote cuda as the greatest thing ever.
The head honchos at nvidia were probably fantasizing that they
could pull a ‘Microsoft’ from circa 1997 and ‘Stomp Out’ their
competition ( anyone remember Netscape ? )

ATI or Nvidia, any guesses for GPU?

CUDA will come first ==> NVIDIA

As a bit of a follow-up question, will double precision be required?
RE: As a bit of a follow-up

There will be CUDA apps that will run also on low-end cards that do not support double precision in the GPU.

Just two more weeks... Don't ask me how I know. ;-)

Collatz Conjecture also suport CUDA - they have better app compared to Aqua....
MilkyWay is working on CUDA app for few months....
The best CUDA app have GPUGRID, then Seti.
Worst Aqua.
New driver 190.38 suport Cuda 2.3, but in BOINC for now only CUDA 2.2 is at work... since driver 185.85.
GPURID requires fast GeForce with minimum 64 SP (to have 2 days return bonus)
Seti works good also on <64SP cards.
