HPE Performance Message Passing Interface

The HPE Performance Software - Message Passing Interface (MPI) is an MPI development environment designed to enable the development and optimization of high performance computing (HPC) applications. The HPE Performance Software - MPI leverages a scalable MPI library and boosts performance of existing MPI applications on HPE HPC clusters without requiring recompilation.

The message passing toolkit is a high-performance communications middleware software that is a component of the HPE Performance Software - Message Passing Interface (MPI). This toolkit is the core of the HPE Performance Software - MPI performance engine as it provides the flexibility users need to develop and run MPI programs.

The HPE Performance Software - MPI includes a tool that uses a wrapper library to run applications compiled against other MPI implementations through the message passing toolkit, without requiring the user to relink or recompile their code. This allows users with applications compiled against the Intel MPI, IBM Spectrum MPI, OpenMPI and Mellanox HPC-X MPI to still run their applications through the HPE Performance Software - MPI engine and increase overall application performance.

The message passing toolkit increases the speed of an application from launch. The environment includes HPE-proprietary software that enables parallel applications to run on multiple hosts in a cluster, resulting in the ability to launch 100,000 cores in a matter of seconds.
