Arguments
<integer>
 is in bytes: 256 | 512 | 1024 | 2048 | 4096 | 8192
Default
4096

=map --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 Insights
     perspective - 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.
