cachesim-sets

Set the cache set size (in bytes) for modeling CPU cache behavior during Memory Access Patterns analysis.

GUI Equivalent

Project Properties > Analysis Target > Memory Access Patterns Analysis > Advanced > Cache sets

Syntax

--cachesim-sets=<integer>

Arguments

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

Default

4096

Actions Modified

collect=map --enable cache-simulation

Usage

NOTE:

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.

advisor collect=map --enable-cache-simulation --cachesim-sets=2048 --cachesim-mode=cache-misses --project-dir=./advi_results -- ./myApplication
