Memory Bandwidth Optimization

The sixth video in our series, produced by Colfax International (https://colfaxresearch.com/), is great for users new to Intel® Xeon Phi™ or users who want to refresh their understanding of Xeon Phi.

This video discusses simple settings that can help developers get the most out of the high-bandwidth memory capabilities of Xeon Phi, and demonstrates the possible performance gain of each using the STREAM benchmark as a case study.

The Many-Core Tools & Techniques series is intended to build awareness about key technologies featured in ALCF’s current and future Intel architectures; to describe those features; and to teach users techniques to assess and improve their use of them.
