Back to top
IBM Platform MPI V9.1 is a high-performance, production-quality implementation of the Message Passing Interface (MPI). It is widely used in the high performance computing (HPC) industry and is considered one of the standards for developing scalable, parallel applications.
Platform MPI maintains full backward compatibility with HP-MPI and applications supported by it. IBM Platform MPI incorporates advanced CPU affinity features, dynamic selection of interface libraries, superior workload manager integrations, and improved performance and scalability.
Platform MPI supports the broadest range of industry-standard platforms, interconnects, and operating systems to help ensure that parallel applications can run almost anywhere. It runs on a variety of hardware and operating environments, including the latest generation of IBM System x® servers. By prequalifying and certifying these platforms, IBM helps clients take the risk out of mission-critical high-performance technical computing deployments.
Platform MPI V9.1 provides integration with IBM Parallel Environment ( IBM PE) Runtime Edition so customers can take advantage of the many tools in IBM PE Runtime Edition, such as IBM PE Debugger, during the run time.
Specifically, IBM Platform MPI V9.1 provides the following enhanced features and functionalities from its previous version:

Focus on portability
IBM Platform MPI enables developers to build a single executable that transparently leverages the performance features of any type of interconnect, thereby providing applications with optimal latency and bandwidth for each protocol. This reduces development effort and enables applications to use the most current technologies on Linux or Microsoft Windows without the need to recompile and relink applications.
Platform MPI is optimized for both distributed (DMP) and shared memory (SMP) environments and provides a variety of flexible CPU binding strategies for processes and threads, enabling better performance on multicore environments. With this capability, memory and cache conflicts are managed by more intelligently distributing the load among multiple cores.
Platform MPI also provides support for Nvidia GPU memory or messaging as well as GPUDirect 2.0. Thus applications running on GPUs can take full advantage of the parallel processing power of GPGPU.
With the support for Windows HPC Server 2008, Platform MPI allows developers targeting Windows platforms to enjoy the benefits of a standard portable MPI and avoid proprietary lock-in.
IBM Platform MPI supports a wide variety of networks and interconnects, enabling the development of applications that will run on more platforms and reducing testing, maintenance, and support costs. Along with the TCP interconnect, Platform MPI provides excellent MPI performance on InfiniBand by providing support for both QLogic Performance Scaled Messages (PSM) and Mellanox IB-Verbs (IBV) interconnects. In addition, Platform MPI supports Mellanox Fabric Collective Acceleration (FCA), which enables it to offload collectives to the InfiniBand fabric, dramatically improving MPI run times.
Through the use of a priority network list built from system configuration files, user environment variables, user command line options, and library hard-coded defaults, Platform MPI can dynamically select the optimal network connection between each node and each other node within a cluster at run time. This maximizes network efficiency so that processes get the data they need quickly.
Key features and benefits
Multicore awareness: IBM Platform MPI provides three key methods to optimize performance on multicore systems:
Comprehensive debugging and troubleshooting tools: Platform MPI incorporates an extensive set of tools, including verification and test tools, application tracing and timing facilities, and performance counters with message sizes and counts. These tools enable application developers and users to maximize application performance.
Tracing and monitoring: MPI-related monitoring presentation can be selected through environment variables to determine presentation of timing and trace information, with no recompilation or relinking of the application. As a result, there is no need to recompile or relink the application.
Multithread safe: Multithreaded applications can fully exploit Platform MPI, and multiple threads can simultaneously request services and conduct communication.
Automatic selection of optimal network: Through the use of a priority network list built from system configuration files, user environment variables, user command line options, and library hard-coded defaults, Platform MPI can dynamically select the optimal network connection between each node and each other node within a cluster at run time. This maximizes network efficiency so that processes get the data they need quickly.
Simplified application development: Platform MPI enables use of a single MPI implementation and a single executable to support a wide array of interconnects, with dynamic runtime selection of interconnect. With Platform MPI, you can run a single application across multiple architectures, Linux distributions, and interconnects. It eliminates the need to recompile applications and MPI libraries, while providing full support for dynamically linked libraries. This means there is no need to recompile for every compiler or interconnect combination.
Linux command line replication: Command line arguments to the application are automatically provided to all MPI processes, avoiding tedious parsing and broadcasting of parameters to other MPI processes.
MIMD support: The Multiple Instruction - Multiple Data (MIMD) model is supported through provisions that launch different executables, which constitute the whole MPI application.
Support for popular debuggers: Platform MPI fully supports Etnus TotalView analysis tools, Allinea's distributed debugging tool (DDT), and standard GNU gdb.
Integration with IBM PE Runtime Edition V1.2 allows users to take advantage of the many tools available in IBM PE Runtime Edition

IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective. IBM does not warrant that systems and products are immune from the malicious or illegal conduct of any party.

Increased uptime: The Electronic Service Agent tool is designed to enhance the Warranty or Maintenance Agreement by providing faster hardware error reporting and uploading system information to IBM Support. This can translate to less wasted time monitoring the "symptoms," diagnosing the error, and manually calling IBM Support to open a problem record. Its 24 x 7 monitoring and reporting mean no more dependence on human intervention or off-hours customer personnel when errors are encountered in the middle of the night.
Security: The Electronic Service Agent tool is designed to be secure in monitoring, reporting, and storing the data at IBM . The Electronic Service Agent tool securely transmits either via the Internet (HTTPS or VPN) or modem, and can be configured to communicate securely through gateways to provide customers a single point of exit from their site. Communication is one way. Activating Electronic Service Agent does not enable IBM to call into a customer's system. System inventory information is stored in a secure database, which is protected behind IBM firewalls. It is viewable only by the customer and IBM . The customer's business applications or business data is never transmitted to IBM .
More accurate reporting: Since system information and error logs are automatically uploaded to the IBM Support center in conjunction with the service request, customers are not required to find and send system information, decreasing the risk of misreported or misdiagnosed errors. Once inside IBM , problem error data is run through a data knowledge management system and knowledge articles are appended to the problem record.
Customized support: Using the IBM ID entered during activation, customers can view system and support information in the "My Systems" and "Premium Search" sections of the Electronic Support Web site at
My Systems provides valuable reports of installed hardware and software using information collected from the systems by Electronic Service Agent .
