Larry says gpu gen4 16lane 50GB/s
gen4 c1100 bifurcated 8+8 matches the GPU, 25GB/s for 8 lanes, 50GB/s for 2 x 8 lanes? can PGP also bring in 50GB/s?
Larry mentioned the possibility of using C1100 (https://www.xilinx.com/products/accelerators/varium/c1100.html) with a bifurcated pcie bus to increase data into the GPU to hopefully 50GB/s. But it looks like it only supports 2 QSFP28 which are 100Gb/s each? So only 20GB/s in total per C1100? So to support the 1TB/s produced by the largest epixUHR we would need ~50 C1100 and either put them into ~25 GPUs, or do 50 C1100 into 50 GPUs.
