OSMOSIS: Enabling Multi-Tenancy in Datacenter SmartNICs
summary
OSMOSIS provides a hardware resource manager that enforces fair multi-tenancy on an open-source RISC‑V 400Gb/s SmartNIC by adding lightweight schedulers for compute and IO, evaluated in cycle‑accurate simulation and synthesis. It uses a hybrid compute scheduler that picks flows by measured PU utilization, and IO fragmentation (software or hardware) to avoid head‑of‑line blocking. Integration adds <5% area overhead on the SmartNIC and achieves up to 60% lower completion times for tenant flows while keeping per‑packet latency within tight line‑rate budgets.
