HN comment orderMatt Pharr wrote a series of posts telling the story of ispc: https://pharr.org/matt/blog/2018/04/18/ispc-origins.html I found them extremely interesting - highly recommended.
They link to a conference paper for the full technical details: "ispc: A SPMD Compiler for High-Performance CPU Programming", https://cloud.github.com/downloads/ispc/ispc/ispc_inpar_2012...
Why would you want to use this instead of OpenCL, which supports SPMD and also provides vector primitives?
