Introduction

NEC MPI is an implementation of the MPI-3.1 standard established by the MPI Forum in 2015. NEC MPI utilizes the shared memory feature on a VH and directly controls InfiniBand to achieve high performance communication.

This guide is organized as follows.

• Chapter 1, Overview of MPI, provides an overview of MPI.
• Chapter 2, Overview of MPI Features, describes the major features of MPI.
• Chapter 3, Operating Procedures, describes how to use NEC MPI, including how to compile, link, and execute MPI programs.
• Chapter 4, Procedure Interfaces, summarizes Interfaces of the MPI procedures.
