I'm on my third WU with an X1900GT, and all three of them are almost identical. I haven't confirmed this with EMIII, but all three have been GPU_lambda_GROMACS. They've all been 25,0000 frames, and they all estimate 2.7-2.9s/frame. Have I really pulled three in a row, or is my computer looping the same one again and again? For that matter, are there any other GPU units to crunch?
