snabb - Snabb: Simple and fast packet networking

•    Lua

---

Snabb (formerly "Snabb Switch") is a simple and fast packet networking toolkit. We are also a grassroots community of programmers and network engineers who help each other to build and deploy new network elements. We care about practical applications and finding simpler ways to do things.

ssd-gpu-dma - Build userspace NVMe drivers and storage applications with CUDA support

•    C

---

This library is a userspace API implemented in C for writing custom NVM Express (NVMe) drivers and high-performance storage applications. The API provides simple semantics and functions which a userspace program can use to control or manage one or more NVMe disk controllers. The API is in essence similar to SPDK, in that it moves driver code to userspace and relies on hardware polling rather than being interrupt driven. By mapping userspace memory directly, libnvm eliminates the cost of context switching into kernel space and enables zero-copy access from userspace. This greatly reduces the latency of IO operations compared to accessing storage devices through normal file system abstractions provided by the Linux kernel.
