Finding Hotspots

You can use the Intel® VTune™ Amplifier to identify the most performance-critical functions in an application running on the Intel® Xeon Phi™ coprocessor (code name: Knights Corner). This tutorial guides you through workflow steps running Hotspots analysis type on a sample application, matrix.

Optimization Notice

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.
