Research
My current research focuses on datapath operating systems for microsecond-scale datacenter systems. Demikernel is a new datapath OS and architecture for microsecond-scale datacenter systems and kernel-bypass devices. Demikernel accommodates heterogenous kernel-bypass devices with a flexible library OS architecture and new high-level datapath API with an asynchronous I/O interface and zero-copy memory semantics for microsecond I/O processing. Demikernel implements this API for RDMA, DPDK and SPDK devices with new nanosecond-scale I/O stacks in Rust. Once ported to Demikernel, microsecond datacenter systems can run across different devices with no code changes.
