cache-simulation

Simulate device cache behavior for your application.

--cache-simulation=<string>

<string> is one of the following:

Argument	Description
off	Disable cache simulation.
single	Simulate GPU memory hierarchy behavior only for the selected target device or CPU cache behavior if no target device is selected.
multi	Simulate cache behavior for all available target devices to remodel performance without re-running the collection.
grf	Simulate general register file (GRF) behavior.

off

collect=tripcounts

collect=roofline

collect=offload

Enabling cache simulation can increase analysis overhead.

Use off to decrease overhead.
Use single with Offload Modeling if you want to model performance for a single target device. You can use this mode for the CPU Roofline collection. This option is equivalent to enable-cache-simulation.
Use multi with Offload Modeling if you want to model performance for several devices or with modified memory parameters without rerunning the Characterization (Trip Count and FLOP) analysis. This option is equivalent to the flex-cachesim option (deprecated).
Use grf to ... This option is equivalent to the enable-grf-simulation option (deprecated).

Run Characterization analysis with cache simulation enabled to model performance for all available devices.
