I have four AMD Radeon HD 5770 and 5870 GPUs (Mac Edition) that I pulled out of 2008 MacPro 3,1 units when I installed NVDIA GeForce GTX (680, 770, 960...) GPUs. I use NVIDIA GPUs to crunch Collatz tasks. However, I cannot crunch Collatz tasks using the AMD GPUs. Is there any way to simultaneously crunch Collatz tasks using an NVIDIA GPU and Einstein tasks using the AMD GPU in the SAME MacPro 3,1? TIA!

I apologize for not exhaustively searching the forum before posting this question. Found the answer in the following thread: "Different projects for 2 gpus". Will see how it works, although I am a bit nervous about the fact that this thread indicates that the tasks are loaded in pairs, meaning that after one GPU finishes its task it will wait for the other GPU to be finished before tasks are loaded for each of them. Hmmmm ....
