There are several libraries and tools leveraging SIMD processors with different techniques. The table below is an attempt to list similar libraries that are known to the authors of VOLK and provide a high-level comparison of libraries. This is not meant to be an authoritative list of SIMD-optimizing projects as much as a resource to begin the decision making process.
