Software Specifications
Standards and Programming Languages
HPE Message Passing Interface (MPI) is compliant with these standards:
- – MPI-3.1
- – OpenSHMEM 1.4
The Message Passing Interface (MPI) standard supports C, C++ and Fortran programs with a library and supporting commands. MPI operates through a technique known as “message passing,” which is the use of library calls to request data delivery from one process to another, or between groups of processes. MPI also supports parallel file I/O and remote memory access (RMA).
In addition, HPE Message Passing Interface (MPI) supports the OpenSHMEM 1.4 standard. The OpenSHMEM standard describes a low-latency library that supports RMA on symmetric memory in parallel environments. The OpenSHMEM programming model is a partitioned global address space (PGAS) programming model that presents distributed processes with symmetric arrays that are accessible via PUT and GET operations.
Support for the MPI and OpenSHMEM standards is built on top of a message passing toolkit (MPT), which is available within the HPE Message Passing Interface (MPI).
Operating System Compatibility
The HPE Message Passing Interface (MPI) is operational on:
- – Red Hat Enterprise Linux (RHEL) 8.9, 8.10, 9.4 and 9.5 on x86_64 and aarch64 platforms
- – SUSE Linux Enterprise Server (SLES) 15 SP5 and SLES15 SP6 on x86_64 and aarch64 platforms
- – Rocky Linux 8.9, 8.10, 9.4 and 9.5 on x86_64 and aarch64 platforms
- – SELinux

HPE Message Passing Interface (MPI) Features
HPE Message Passing Interface (MPI) consists of the MPI library, message passing toolkit, and several complementary libraries and profiling and analysis tools that enable and speed development of scalable HPC applications.
The Message Passing Toolkit (MPT) is a high-performance communications middleware software that is a component of the HPE Message Passing Interface (MPI). This toolkit is the core of the HPE Message Passing Interface (MPI) performance engine as it provides the flexibility users need to develop and run MPI programs. The MPT 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.
The HPE MPI library accelerates performance of all HPE HPC systems and wide variety of interconnects (as per Specifications).
HPE Message Passing Interface (MPI) also includes a tool that uses a wrapper library to run applications compiled against other MPI implementations through MPT, without requiring the user to relink or recompile their code. This allows users with applications compiled against Cray MPI, Intel® MPI, IBM Spectrum MPI, Open MPI, Mellanox X-MPI, MPICH, MVAPICH
to still run their applications through the HPE Message Passing Interface (MPI) engine and increase overall application performance.
Application Performance Optimization
- – HPE Message Passing Interface (MPI) accelerates application performance through tools designed to tune applications at runtime without recompiling code, as well as libraries which optimize performance through specialized algorithms.
- – These tools and libraries allow customers to:
- – Restrict the number of processor and memory resources used for a specific process, or set of processes to avoid oversubscribing the system and possible interference between applications.
- – Improve performance for I/O-intensive applications without recompiling or retooling the software logic.
- – Enable data placement to specific memory locations to limit communications overhead.
Users also gain access to profiling and analysis tools with HPE Message Passing Interface (MPI). One such tool captures communication analytics, pinpoints bottlenecks and identifies load imbalances during the application run. Once the tool is implemented and the application completes its run, users will receive a file outlining key statistics from the run.
This information includes:
- – Time spent in computation, communication and file I/O
- – The size and number of each data request
- – The size of the communicator used for collectives
- – The number of times each rank was a root in a collective
- – Size distributions
- – Collective wait time and send late time
Users also have the option to analyze subsets of the application run by inserting start and stop commands into their program. The tool will begin analyzing the application run when the start command is executed and will generate the statistics file after the stop command is executed.
The profiling and analysis tools available within HPE Message Passing Interface (MPI) can be used for applications compiled against the Cray MPI, Intel®MPI, IBM Spectrum MPI, Open MPI, Mellanox X-MPI, MPICH and MVAPICH.
Additional features within the HPE Message Passing Interface (MPI) environment include a runtime tool to optimize processes and data placement on a set of nodes.
HPE Message Passing Interface (MPI) includes tools to optimize the placement of worker processes within the cluster. Users first run their application with HPE MPI’s profiling tool to record the communication pattern between the workers. In future runs, the MPI’s placement optimization tool takes this pattern information and combines it with information about where the application will be running to create a placement file assigning workers to specific locations in the cluster. This improves performance by putting workers that intercommunicate a lot close to each other, minimizing transfer costs.
It is important for HPE Message Passing Interface (MPI) fabric support to drive performance and resource optimizations, features include:
- – Adding more resources to a running application with MPI spawn is available for systems using Intel® Omni-Path, Mellanox® InfiniBand, TCP/IP, and HPE Superdome Flex Grid technology
- – Faster MPI performance for systems with NVIDIA® GPU with Mellanox® InfiniBand remote direct memory access (RDMA)
- – Increase application performance by creating fewer memory copies and non-blocking activity with Mellanox InfiniBand™ tag matching
