Command Line Analysis

This analysis is deprecated in GUI and available from command line only.
TSX Hotspots analysis type uses hardware event-based sampling collection and is targeted for the Intel® processors supporting Intel Transactional Synchronization Extensions (Intel TSX). This analysis type uses the UOPS_RETIRED.ALL_PS hardware event that emulates precise clockticks and helps identify performance-critical program units inside transactions.

Syntax

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.
