cachesim-cacheline-size
Set the cache line size (in bytes) for modeling CPU cache behavior during Memory Access Patterns analysis.
GUI Equivalent
Project Properties > Analysis Target > Memory Access Patterns > Advanced > Cache line size
Syntax
--cachesim-cacheline-size=<integer> |
Arguments
<integer> is in bytes: 4 | 8 | 16 | 32 | 64 | 128 | 256 | 512 | 1024 | 2048 | 4096 | 8192 | 16384 | 32768 | 65536
Default
64
Actions Modified
collect=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 four-way associative cache with 64-byte cache line size and default cache set size.
