Intel® Advisor
 User Guide

is composed of a set of tools to help ensure Fortran, C and C++ (as well as .NET on Windows*) applications realize full performance potential on modern processors:
  • Vectorization Advisor
     is a vectorization optimization tool that lets you identify high-impact, under-optimized loops, what is blocking vectorization, and where it is safe to force vectorization. It also provides code-specific how-can-I-fix-this-issue recommendations. For details about the Vectorization Advisor workflow, see Vectorization Workflow Diagram.
  • Roofline Analysis
     visualizes actual performance against hardware-imposed performance ceilings (rooflines). It provides insights into where the bottlenecks are, which loops are worth optimizing for performance, what are the likely causes of bottlenecks and what should be the next optimization steps. For details, see CPU Roofline Analysis or GPU Roofline Analysis.
  • Threading Advisor
     is a fast-track threading design and prototyping tool that lets you analyze, design, tune, and check threading design options without disrupting your normal development. For details about the
    Threading Advisor
     workflow, see Threading Workflow Diagram.
  • Flow Graph Analyzer
     is a visual prototyping tool that lets you represent and analyze performance for applications that use the Intel® Threading Building Blocks (Intel® TBB) flow graph interfaces. For typical
    Flow Graph Analyzer
     workflows, see the Flow Graph Analyzer section of this guide.
  • Offload Advisor
     (
    Intel® Advisor Beta
     only) allows you to identify high-impact opportunities to offload to GPU as well as the areas that are not advantageous to offload. It provides performance speedup projection on accelerators along with offload overhead estimation and pinpoints accelerator performance bottlenecks. For details about the
    Offload Advisor
     workflow, see the
    Offload Advisor
     section of this guide.
Intel® Advisor

Product and Performance Information

1

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.
