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.

With 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.

Network optimization

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 runtimes.

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 runtime. This maximizes network efficiency so that processes get the data they need quickly.

Key features and benefits

Product capabilities

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 for recompilation or relinking 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 runtime. 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/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.

Statement of good security practices
Bottom rule

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.
