DescriptionToday’s largest FPGAs have impressive performance potential—with Intel’s Stratix 10 boasting 9.2 TFLOPS and Xilinx’ UltraScale+ VU13P offering 3.8M logic elements. This, in addition to direct access to high-speed memory and networking, is making FPGAs a top choice for high-performance computing in datacenters.
However, the potential continuous power draw of these large FPGAs is now 200 watts and up, meaning significant heat that must be removed. While it’s easy to simply add liquid cooling or fans if you’re targeting a desktop, datacenter servers prefer compact, passive solutions.
The solution is a thermals first approach. This isn’t about a particular technology (although we’ll cover the latest options) but a combination of elements, including physical board design, flow simulation informed by a proper understanding of airflow in servers, and more. This presentation will be informative for anyone seeking to learn about the latest large FPGAs in production servers.
