Stride and Memory Access Patterns

Overview

This video demonstrates how memory access patterns can affect the performance of a program, and how to use the MAP report to diagnose these issues. It also provides a quick explanation of the efficiency column of the survey report.

For additional background information, see the supplemental video, Memory Access 101.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserverd for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
