Abstract

The SiCortex cluster systems implement a high-bandwidth, low-latency interconnect. We describe how the SiCortex systems implement RDMA, including zero-copy data transfers and user-level networking. The system uses optimistic virtual memory registration without page locking. Finally, we provide preliminary performance results.
