Multi Vender GPU rendering

In case you guys haven't seen this a company called Lucid http://www.lucidlogix.com/ is working on a chip called the hydra that will allow people to mix and match various vendors, and gpus in one system. More information can be found at the following links.

The good thing about this is opencl is supported so you could use nvidia and ATi cards to crack hashes.

Even better the company has something called the adventure series that allows gpu expansion, so those that only have room for 3 GPU's in your current system can support 4more PCI-E slots using this system. - http://www.lucidlogix.com/product-adventure2000.html
Haven't seen it for sale anywhere yet but something I might look into.

I bet it wouldn't work in real applications :-)
Users already have much pain with multi-GPU even for same GPU :-)

I guess cost of this device (for +4 PCI-E) will be higher than cost of motherboard + case + PSU. As it always happens with non-standard solutions.

I keep going back and forth with this in my head. I already have two systems filled with 295GTXs, and for the most part one of them sits and does nothing, while the other is always busy. It just boils down to the fact that EDPR(elcomsoft distributed password recovery) is pretty much the only distributed system, and it doesn't support nearly the amount of hashing algorithms as the software that only supports single systems out there. (ie:bars, ighashgpu, EGB. etc)

So I'll probably be stuffing as many GTX 300 series cards into one system (i'm guessing 8 is the limit) when they come out. Unless a distributed system comes out that is able to support the hashing algorithms I need it will not be worth it to have many smaller nodes.

By the way EDPR is dog slow. ighashgpu is faster on one machine alone compared to every one of my machines running EDPR to crack MD5 hashes.
