OMRC: Multipath Reliability for Direct-Connect Optical Interconnects
Eric Ding, Keshav Pradeep, Rachee Singh
Network failures degrade Multipath Reliable Connection (MRC) in direct-connect optical datacenters. We propose Optical MRC (OMRC), which remaps collectives and circuits, preserving…
Opus: Photonic Rail-Optimized Fabric in ML Datacenters
Eric Ding, Barry Lyu, Bhaskar Kataria +1
Rail-optimized network fabrics have become the de facto datacenter scale-out fabric for large-scale ML training. However, the use of high-radix electrical switches to provide all-t…
Morphlux: Transforming Torus Fabrics for Efficient Multi-tenant ML
Abhishek Vijaya Kumar, Eric Ding, Arjun Devraj +2
We develop Morphlux, a server-scale programmable photonic fabric to interconnect accelerators within servers. We show that augmenting state-of-the-art torus-based ML data-centers w…
Photonic Rails in ML Datacenters
Eric Ding, Chuhan Ouyang, Rachee Singh
Rail-optimized network fabrics have become the de facto datacenter scale-out fabric for large-scale ML training. However, the use of high-radix electrical switches to provide all-t…
PipSwitch: A Circuit Switch Using Programmable Integrated Photonics
Eric Ding, Rachee Singh
We present an optical circuit switch design for programmable integrated photonics (PIPs). Our solution finds the correct and optimal set of matchings that provides all-to-all netwo…
