It is a high-performance implementation of messaging design patterns, including some that are MQ-like. I believe it had aspirations to be an MQ many years ago but turned into an MPI-like high-performance messaging library that abstracts network, IPC, and in-process communication. The basic network performance and scalability of ZeroMQ is similar to MPI. Underneath the hood it is just a collection of lockless, async structures grafted to the usual operating system hooks. Thinking of it as a competitor to MPI in terms of basic functionality is probably the correct framing. J.
