Diagnostics: Aggregated Execution Count was Used

Symptoms

A code region of interest has
Aggregated execution counts
were used diagnostics message in the
Diagnostics
column.

Cause

This means that execution counts in the Top-Down are not available or incorrect, so Offload Advisor aggregated the loop/function to the Bottom-Up and used the aggregated execution counts to estimate performance.

Possible Solution

  • This may not be a problem if your kernel is called on a single call path. No correction required.
  • If your kernel is called on multiple call paths, you might try to rerun the collection and performance projection to fix the metrics attribution problem. If this does not help, please use the Analyzers community forum for technical support.

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.
