Hi John, Mark Wagner has worked on a design that we will take to the DSN 70m in Canberra:
2 basebands 400 MHz 16384 channels running on one ROACH. This was based on a 1M channel design. He would be a good contact, in particular about the level of optimization and available real estate. I look forward to learning at the August workshop more about approaches mating GPUs and ROACH/IBOBs. 0 Best, Lincoln -- Lincoln J.

Hi all. I know folks are working on a hybrid spectrometer using roach/ibob and GPU's. I am in need of a 1M channel, 2 pol, 400 MHz spectrometer. Anyone offer up their design as a possibility? I think GUPPI maybe could do it, but I wonder if anyone else has gotten anything going. Or could you build such beast with just a roach or 2? John
