Intel® Cluster Checker version 1.6 New Features and Enhancements

Intel® Cluster Checker version 1.6 provides many new and improved features (see the product documentation for more details).

General Description

The new features included in this version of our cluster verification tool, were developed with the regular (not privileged) user in mind. Now, for example, a regular user will be able of checking hardware uniformity and I/O performance. Some other new features were also added to improve the user experience: a centralized approach for network fabric selection, a standard output directory, an output log analyzer, the source for an XML parser for output logs, and a new experimental mode for reverse execution.

Regular User

  • This version considers the operation by regular (not privileged) users as the target usage scenario, to achieve this, the dmidecode and hdparm test modules were replaced by the hardware_uniformity and disk_bandwidth test modules respectively.

Compliance to Multiple Specification Versions

  • The tool now verifies compliance against multiple versions of Intel® Cluster Ready specification during the same execution run.

Optimized Execution Tim


  • The execution time was also a prime target of this release, and with the enhancements in the most time consuming test modules significant reductions for different execution modes were achieved.

Standard Output Directory

  • To simplify housekeeping, a standard output directory is set by default, which is also configurable by the user.

Network Fabric Configuration Abstraction

  • The engine now supports a centralized approach for network fabric selection inside the global_configuration container in the configuration file.

Benchmarks Update

  • Prepackaged benchmarks were updated to apply advanced optimizations and to leverage new platform support offered by the latest Intel Cluster tools release, namely Intel MPI Library 4.0.1, Intel Fortran/C++ Compiler 12.0 and Intel Math Kernel Library 10.3.

Last Output Report

  • A new option was added that looks for Intel Cluster Checker output logs and gives a general report with useful data such as the last passing certification log, or the failed modules of the latest runs.

Output XML Parser

  • The source code for an XML parser is included as reference for developers to process output log files.

Reverse Execution Mode

  • A new experimental execution mode was added, which runs the modules with more dependencies first, and only runs their dependencies if they fail to root-cause the failure. This execution approach aims to reduce the execution time by assuming a positive outcome.

Intel Cluster Checker is a really useful tool that keeps getting better. I'm glad to see it continually improved upon; the last-output report looks particularly handy. :)
