enforce-baseline-decomposition

Use the same local size and SIMD width as measured on a baseline device.

Syntax

--enforce-baseline-decomposition
--no-enforce-baseline-decomposition
Default
Off (no-enforce-baseline-decomposition)
Actions Modified
collect
=projection --profile-gpu
Usage
This option is applicable only to the GPU-to-GPU performance modeling workflow.
When used with the Performance Modeling (
collect=projection
) as part of the GPU Roofline Insights perspective for an application executed on a GPU, your application performance is modeled for a baseline GPU device as a target. The estimated performance is compared with the actual application performance to add more recommendations for performance optimization.
This option is recommended to be used with the
model-baseline-gpu
option.
Example
Run the GPU-to-GPU Performance Modeling for the baseline GPU using the same local size and SIMD width as on the baseline device.
$ advisor --collect=projection --profile-gpu --model-baseline-gpu --enforce-baseline-decomposition --project-dir=./advi_results -- ./myApplication
