Kernel-bypass networking assumes NIC features the cloud won’t give tenants. Machnet is a userspace stack that hits near bare-metal tail latency inside cloud VMs using only the minimal vNIC feature set every provider supports – via a shared-memory sidecar and “RSS–,” a trick that probes port combinations to steer flows through the cloud’s opaque, unconfigurable RSS hashing. I’ll cover the design and the tradeoffs.
I am a Ph.D. Candidate in Computer Science at Columbia University, advised by Kostis Kaffes. I focus on hardware-software co-design, kernel-bypass networking, and low-latency systems optimization - squeezing everything out of whatever hardware I'm given, whether that's a CPU, NIC, GPU, or TPU. I previously worked at Microsoft Research (Networking Research Group) and Google (TPU Performance). My research has appeared at ASPLOS, NeurIPS MLSys, and VLDB.
