cachesim

Enable cache simulation for Performance Modeling.

Syntax

--cachesim

--no-cachesim

Default

On (cachesim)

Actions Modified

collect=projection

Usage

Cache simulation data might be unavailable for some loops. Performance Modeling result may be incorrect. Use this option to enable the cache simulation data for the Performance Modeling.

NOTE:
Make sure to use the --enable-cache-simulation and --cache-config command line arguments when collection Trip Counts data to improve projection accuracy.

Example

  1. Run Survey Analysis.

  2. Run Trip Counts and FLOP analyses of the Characterization stage with cache simulation for a specific cache configuration.

  3. Model your application performance and explicitly enable cache simulation .

advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication
advisor --collect=tripcounts --flop --enable-cache-simulation --cache-config=4:8w:32k:64l/4:4w:256k:64l/1:16w:6m:64l --project-dir=./advi_results -- ./myApplication
advisor --collect=projection --cachesim --project-dir=./advi_results
