How to use the Intel® Cluster Checker v3 SDK with gcc5

When compiling connector extensions in the Intel® Cluster Checker v3 SDK it is recommended to use an Intel compiler version 15.0 or newer and a gcc/g++ compiler version 4.9.0 or newer, as described in the Intel® Cluster Checker developer's Guide. This explicitly includes gcc version 5.1.0 and newer as well.

  • How to use the Intel® Cluster Checker v3 SDK on a cluster using multiple Linux Distributions

    Linux based HPC clusters can use different Linux distributions or different versions of a given Linux distribution for different types of nodes in the HPC cluster. When the Linux distribution on which the connector extension has been built uses a glibc version 2.14 or newer and the Linux distribution where the connector extension is used, i.e. where clck-analyze is executed, uses a glibc version lower than 2.14, clck-analyze is not able to execute the shared library of the connector extension due to a missing symbol.

  • How to achieve an Intel® Cluster Ready Certification with Intel® Cluster Checker v3.0 on a Cluster using Mellanox InfiniBand HCAs

    This article describes the steps that are necessary to achieve an Intel® Cluster Ready Certification using Intel® Cluster Checker v3.0 on a cluster using the Mellanox InfiniBand cluster interconnect. In order to comply with the requirements of the Intel® Cluster Ready architecture specification, certain aspects of the cluster configuration have to be checked. Those requirements may not necessarily be checked for when checking for cluster health only. For clusters based on the Mellanox based InfiniBand interconnect this requires testing the DAPL message fabric interface and the TCP based fabric.

  • How to handle mismatched InfiniBand HCA and switch speed with Intel® Cluster Checker v3.0

    Intel® Cluster Checker v3.0 can detect the type of the InfiniBand Host Channel Adapter (HCA) that is installed in a cluster node. It can also determine what the expected performance for a given HCA is and use that performance to compare measured performance values with.

    Intel® Cluster Checker v3.0 does not have the ability to detect the InfiniBand switch type and can, therefore, not determine what the maximum possible performance of the overall InfiniBand fabric can be.

  • How to achieve an Intel® Cluster Ready Certification with Intel® Cluster Checker v3.0 on clusters with non-identical configuration of head and compute nodes

    This article describes the steps that are necessary to achieve an Intel® Cluster Ready Certification using Intel® Cluster Checker v3.0 on a cluster where the head node and compute nodes are using different hardware or software configurations. The compute nodes use identical hardware and software configurations.

  • How to achieve an Intel Cluster Ready Certification with Intel® Cluster Checker v3.0 on a Cluster using the Intel® True Scale Fabric

    This article describes the steps that are necessary to achieve an Intel® Cluster Ready Certification using Intel® Cluster Checker v3.0 on a cluster using the Intel® True Scale fabric. In order to comply with the requirements of the Intel® Cluster Ready architecture specification 1.3.1, certain aspects of the cluster configuration have to be checked. Those requirements may not necessarily be checked for when checking for cluster health only. For clusters based on the Intel® True Scale fabric this requires testing the DAPL provider interface in addition to the native TMI message fabric interface and the TCP based fabric.
