An everything bagel for the brain. Substantive, layered, well-seasoned.
Summary
Corundum is an open-source, high-performance FPGA-based Network Interface Card (NIC) and platform designed for in-network compute applications. The project features a high-performance datapath supporting 10G/25G/100G Ethernet, PCI Express Gen 3, and includes a custom PCIe DMA engine. It supports many queues (1000+ transmit, receive, completion, and event queues), scatter-gather DMA, multiple ports, and hardware timestamping. The platform is designed for both traditional networking and in-network compute applications, with features like multiple PTP hardware clocks, flow hashing, RSS, checksum offload, and interrupt moderation. The project is open source with comprehensive documentation and community support channels.
