At GTC 13 last year, the guys from General Electric gave a standing-room-only presentation about how they’re using RDMA (Remote Direct Memory Access) to drive multi-GPU process performance to new heights. They came back to GTC14 to talk about new and innovative applications of GPU technology they’re cooked up over the past year.
In this session, Dustin Franklin, GE GPU Applications Engineer guru, gives us an update on how it has been proceeding with RDMA and how it allows the electric company to build large scale, multi-node products.
What’s really interesting are the types of products that this is now making possible. For example, consider software-defined radar. With a big RF transmitter and enough fast computing power, you have the ability to do a lot of different things.
The same radar dome can be used for MTI (Moving Target Radar), SAR (Synthetic Aperture Radar), radar-jamming, and even as a communications channel. Using GPUs to configure the output and interpret the returning waves, GE has found that it’s possible to do all of these functions simultaneously.
