Alpha Data demos three linked FPGA cards based on Kintex UltraScale performing real-time 3D Ray Casting/Volume Rendering

Alpha Data had a nice, real-time 3D ray-casting and volume rendering demo in its booth at last week’s SC17. The demo harnesses three Alpha Data ADM-PCIE-KU3 FPGA cards based on Xilinx Kintex UltraScale KU060 FPGAs. A model of a buckyball volumetric data set is distributed to the three cards, which are then teamed to perform ray casting and 3D color rendering in real time. Of particular note: the three FPGA cards perform the video rendering at 43fps while consuming a little more than 2J. The same task running on an i5 x86 processor renders only 2fps while consuming more than 52J. That’s a 20x speed improvement and a 25x improvement in energy consumption resulting in a 400x speed/energy improvement.


Here’s a 2-minute video of the SC17 demo:
