Memory sub-system components contribute significantly to the performance characteristics of an application. As an increasing number of threads or processes share the limited resources of cache capacity and memory bandwidth, the scalability of a threaded application can become constrained. Memory-intensive threaded applications can suffer from memory bandwidth saturation as more threads are introduced. In such cases, the threaded application won’t scale as expected, and performance can be reduced. This article introduces techniques to detect memory bandwidth saturation in threaded applications.

This article is part of the larger series, “Intel Guide for Developing Multithreaded Applications,” which provides guidelines for developing efficient multithreaded applications for Intel® platforms.
