Panel Discussion: Enabling HPC/AI Disaggregated System Architectures with Optical I/O

Jun 23, 2021 | Resources, Video

Disaggregated architectures decoupling memory from processors and accelerators allow for more flexible and cost-effective node designs that can meet the demands of next-generation HPC and AI workloads. For disaggregation to be possible, an I/O interconnect technology that can deliver high bandwidth throughput at low power and low latency over a relatively long distance of a few meters to 100s of meters is critically needed. Compute Express Link (CXL), an emerging unified protocol for disaggregated systems, uses PCIe electrical signaling for I/O interconnect which has limited reach. To extend the reach and fanout, there is strong interest for a “CXL over Optical” I/O interconnect. What optical I/O technology is best suited for this? In this panel discussion, we hear from experts who are building and exploring disaggregated architectures and are wrestling with the challenges of I/O interconnects.
