Measuring Memory Bandwidth on the Intel® Xeon Phi™ Coprocessor

The memory bandwidth of an application is an important metric to have at your fingertips when optimizing your application. One can measure the memory bandwidth of an application running on the Intel Xeon Phi coprocessor by one of the two ways: by using the core hardware events or by using the uncore hardware events.

Dissecting STREAM benchmark with Intel® Performance Counter Monitor

Intel® Performance Counter Monitor (Intel® PCM) is an API and a set of tools that should help developers to understand how their applications utilize the underlying compute platform. In this blog I will explain how to instrument the well-known STREAM benchmark with library functions of Intel® PCM reading statistics directly from integrated memory controllers available on the latest Intel® Xeon® 5500, 5600, 7500 and Core™ processor series.
