Bundling Compilers and Cluster Tools for Intel® IA-32, IA-64, and Intel® 64 architectures, the Intel® Cluster Toolkit Compiler Edition 3.1 provides Windows or Linux versions of the Intel Compilers for C++ and Fortran in addition to the Intel® Cluster Tools for a software package unrivaled by any other offerings.

The Intel Cluster Toolkit Compiler Edition 3.1 license provides access and support for the following programs on either Windows CCS or Linux:

• Intel® C++ Compiler 10.1
• Intel® Fortran Compiler 10.1
• Intel® MPI Library 3.1
• Intel® Trace Analyzer and Collector 7.1
• Intel® Math Kernel Library 10.0
• Intel® MPI Benchmarks 3.1
• Intel® Debugger 10.1 (except with Windows Intel® MPI Library applications)

The latest releases of all the Cluster Tools have increased performance and ease-of use while improving interoperability, scalability, and the number of user options.

Intel Cluster Toolkit Compiler Edition 3.1 integrates your compiler of choice with the Cluster Tools, provides easy installation, and comes with extensive documentation. With a valid product serial number for the Intel Cluster Toolkit Compiler Edition, you can register and/or login to the Intel® Software Development Products Registration Center and download the package and updates for one year from the date of purchase. Extended support agreements are also available. See the left side toolbar for additional support resources including community forums, compatibility, and solutions.

All the software tools included with Intel Cluster Toolkit Compiler Edition have undergone a major revision to give you the best parallel performance analysis tools for cluster software development.

The following list contains just a few of the many new features included in this latest version.
