--enable cache-simulation
Usage
Cache simulation modeling applies to the following:
- 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.
- CPU / Memory Roofline Insightsperspective - This enhanced simulation functionality models multiple levels of cache for a downstream Memory-Level Roofline chart or Roofline interactive HTML report.
This option is applicable only to Memory Access
Patterns analysis.
Example
Run a Memory Access Patterns analysis. Model cache
misses for 2048-byte cache set size, default cache associativity and cache line
size.
