Massively Parallel Processor. A parallel computer that employs a scalable architecture that can scale to hundreds if not thousands of processors. Due to the bandwidth limitations of shared-memory architectures, MPP machines are almost always based on a distributed-memory, message-passing architecture.
A high-performance computing (HPC) architecture that uses dozens, hundreds or even thousands of processors operating in parallel. Specifically, 32 or more processors. See HPC and supercomputer.
