Usage
Enabling can increase collection overhead.
Cache simulation modeling applies to the following
analyses
:
  • Memory Access Patterns
    analysis
    - This basic simulation functionality models accurate memory footprints, miss information, and cache line utilization for a downstream Memory Access Patterns report.
  • Trip Counts and FLOP / Roofline - This enhanced simulation functionality models multiple levels of cache for a downstream Memory-Level Roofline chart or Roofline interactive HTML report.
Run a Memory Access Patterns analysis. Enable cache simulation with basic functionality and default cache parameters to collect cache modeling data for a downstream Memory Access Patterns report.
$ advixe-cl --collect=map --project-dir=./advi --enable-cache-simulation -- myApplication
Run a Roofline analysis for all memory levels.
$ advixe-cl --collect=roofline --enable-cache-simulation --project-dir=./advi -- myApplication

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.
