search-n-dim
search-n-dim
Enable searching for an optimal
N-dimensional offload.
Syntax

Usage
search-n-dim
enables combining up to
three nested
parallel
loops into an N-dimensional offload. This can reduce estimated
execution time on GPU and Time by Compute.
Use
no-search-n-dim
to estimate offloading for each loop
separately.
- Run Survey Analysis.
- Run Trip Counts and FLOP analyses of the Characterization stage.
- Do not search for an optimal N-dimensional offload when modeling your application performance on a target device.
