Syntax

--data-transfer=off | light | medium | full

Arguments

Argument

Description

off

Disable data transfer simulation.

light

Model data transfer between host and device memory.

medium

Model data transfer between host and device memory, attribute memory objects to the analyzed loops that accessed the objects, and track accesses to stack memory.

full

Model data transfers, attribute memory objects, track accesses to stack memory, and identify where data can be potentially reused if transferred between host and target.

Default

off

Actions Modified

collect=tripcounts

collect=offload

Usage

Usage can increase analysis overhead.

NOTE:

data-transfer option takes precedence over the enable-data-transfer-analysis option and its modifications. So if you specify both, data-transfer rewrites all enable-data-transfer-analysis modifications used.

Example

  1. Run Survey Analysis.

  2. Run Trip Counts and FLOP analyses of the Characterization stage with full data transfer simulation.

  3. Model your application performance on a target device.

advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication
advisor --collect=tripcounts --flop --data-transfer=full --project-dir=./advi_results -- ./myApplication
advisor --collect=projection --project-dir=./advi_results
