Specify total time, in milliseconds, to filter out loops that fall below this value.

Syntax

--loop-filter-threshold=<integer>

Arguments

<integer> is a total execution time threshold, in milliseconds.

Default

20

Actions Modified

collect=projection

Usage

Use to ignore loop nests with total time less than the threshold.

Example

  1. Run Survey Analysis.

  2. Run Trip Counts and FLOP analyses of the Characterization stage.

  3. Ignore loops with total time less than 50 milliseconds when modeling your application performance on a target device.
