I was reading a post about a company that uses GPGPU technology based on CUDA to crack passwords.
They are claiming that they were able to execute their software on ATI cards as well



see that post for yourself

radiance could you give them a call ?

based on the specs ATi cards are able to deliver by far more GigaFlops than Nvidia.

Why should we wait a year or so for nvidia to get to that level ? and who knows what ati could deliver then.
I am not a brand fanatic but if it can be done it would be nice
I think the support of both brands would be better from your business perspective too !!

where's the fermi GTX400 series benchmarks ?
ATI support through OpenCL is slow.

We will add an opencl renderer once we're %100 sure about to future of opencl and the performance. (performance is a disaster compared to cuda currently)

indeed opencl is slower than cuda

according to that post they are somehow using cuda with ati !!! ??

i don't know if it is that the case but it looks like it.

but should not be binary compatible....

probably they could answer that question to you however you know the details better.

maybe it was older code which was using just simple opengl calls and the CUDA badge was just for marketing reasons

maybe they have a second version of the code running using STREAM ATI's cuda equivalent

maybe porting the important parts of octane to stream could be .... "easy"

but you are right cuda is good and fast indeed

I don't see anything in that post that even hints that they are using CUDA to break passwords, let alone using CUDA on an ATI card to break passwords.

Yes they refer to the developer friendly nature of Nvidia and CUDA but don't say that their implementation uses it. They say that they have updated their software such that it can work with both ATI and Nvidia at the same time. They don't say what libraries interfaces they are using for each card either. So this is a non story really.

it's impossible to use cuda on ATI cards, as CUDA compiles binary code for 8000, 9000, GTX200 and fermi architectyres.
these are vastly different from ati architectures.

it would be like trying to run intel code on a powerpc CPU.
