Arguments
Argument
| Description
|
|---|---|
off
| Disable data transfer simulation.
|
light
| Model data transfer between host and device memory.
|
full
| 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.

Usage
Usage can increase analysis overhead.
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.
- Run Survey Analysis.
- Run Trip Counts and FLOP analyses of the Characterization stage with full data transfer simulation.
- Model your application performance on a target device.
