Command Line Analysis

This analysis is deprecated in GUI and available from command line only.
SGX Hotspots analysis type is targeted for systems with Intel Software Guard Extensions (Intel SGX) feature enabled. It uses the INST_RETIRED.PREC_DIST hardware event that emulates precise clockticks and helps identify performance-critical program units inside security enclaves. Using the precise event is mandatory for the analysis on the systems with the Intel SGX enabled because regular non-precise events do not provide a correct instruction pointer and therefore cannot be attributed to correct modules.

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.
