Store Bound

Metric Description

This metric shows how often CPU was stalled on store operations. Even though memory store accesses do not typically stall out-of-order CPUs there are few cases where stores can lead to actual stalls.

Possible Issues

CPU was stalled on store operations for a significant fraction of cycles.

Tips

Consider False Sharing analysis as your next step.

Product and Performance Information

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 reserved 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.
