Intel's Cache Monitoring Technology: Software Support and Tools

Introduction

Intel's Cache Monitoring Technology (CMT) feature was introduced with the Intel®Xeon® E5 2600 v3 product family in 2014.  This feature enables fine-grained tracking of L3 cache occupancy, enabling detailed profiling and tracking of threads, applications or VMs.

Previous blog posts referenced below provide an overview of various aspects of the feature:

Getting Kernel-Based Virtual Machine (KVM) to Work with Intel® Xeon Phi™ Coprocessors

The current Kernel-based Virtual Machine (KVM) software does not recognize the existence of Intel® Xeon Phi™ coprocessors. In order to make the KVM recognize the coprocessors, we provide patches under the GPL license, to rebuild the kernel and qemu-kvm packages. The patches provided here are used for Red Hat Enterprise Linux* 6.2 (RHEL* 6.2).

Attached is a step-by-step procedure on how to make KVM on RHEL* 6.2 recognize Intel® Xeon Phi™ coprocessors, including a zip file of the patches.
