对于在群集上运行的分布式内存应用程序，使用“英特尔® MPI 库”可以减少 QA 测试工作量，并提供出众的消息传递灵活性。构建一个版本的目标应用程序，便能在多种群集互连结构上运行，具体使用哪种结构，可由用户在运行时选择。针对使用 IA-32 与安腾处理器、含“英特尔® 扩展内存 64 位技术”（英特尔® EM64T）的处理器的群集进行开发。“英特尔 MPI 库”支持基于“传输控制协议”(TCP) 的以太网消息传递、基于共享内存结构的“共享内存”消息传递、以及基于 RDMA 的 InfiniBand* 结构消息传递。
Implementing the high performance MPI-2 specification on multiple fabrics, Intel® MPI Library 3.1 focuses on making applications perform better on IA based clusters. Intel MPI Library enables you to quickly deliver maximum end user performance even if you change or upgrade to new interconnects, without requiring major changes to the software or to the operating environment. Intel also provides a free runtime environment kit for products developed with the Intel MPI library .
Features
Intel® MPI Library is a multi-fabric message passing library that implements the Message Passing Interface, v2 (MPI-2) specification. It provides a standard library across Intel® platforms that:
- Focuses on making applications perform best on IA based clusters
- Enables adoption of the MPI-2 functions as the customer needs dictate
- Delivers best in class performance for enterprise, divisional, departmental and workgroup high performance computing
Intel® MPI Library is available for Windows* Compute Cluster Server 2003 or for Linux* in all of the following packages
- Intel MPI Library Free Runtime Environment for pre-installation or redistribution
- Intel MPI Library Software Development Kit including compilation tools, interface (static) libraries, debug libraries, trace libraries, include files and modules, and test codes
- Intel® Cluster Toolkit
- Intel® Cluster Toolkit Compiler Edition
Why Intel MPI Library?
- High performance MPI-2 implementation
- Linux and Windows CCS support
- Interconnect independence
- Smart fabric selection
- Easy installation
- Free Runtime Environment
- Close integration with the Intel and 3rd party development tools
- Internet based licensing and technical support
Intel® MPI Library Supports Multiple Hardware Fabrics
Whether you need to run TCP sockets, shared memory, or one of many DAPL-based interconnects, including InfiniBand, Myrinet*, and Quadrics, Intel® MPI Library covers all your configurations by providing an accelerated universal, multi-fabric layer for fast interconnects via the Direct Access Programming Library (DAPL) methodology (Figure 1). Develop MPI code independent of the fabric, knowing it will run efficiently on whatever fabric is chosen by the user at runtime.
Intel® MPI Library Interoperability
Standards Based - Intel® MPI Library is based on Argonne National Laboratory's MPICH-2 implementation and is targeted toward industry-wide standardization of the MPI-2 ABI with maximum performance. All MPI-1 features are supported, plus many MPI-2 features including the following:
- Active target one-sided communication
- Passive target one-sided communication
- Generalized requests
- Full thread support
- File I/O
