how to use ParallelDevicePerformanceProfile

[njuxyh]

Hi supporter:
in the webinar, there is an introduction about ParallelDevicePerformanceProfile , but I do not know how to use it.
because I have not found the option in the vnl, it is done by writing scripts manually?

Hi,

yes, it has to be done by scripting. The easier workflow is:

1) Create the script you need using the Script generator.

2) Send it to the editor

3) Comment out the line:
device_configuration.update()

4) Add the following line, including the desired values for processes and threads:
profile = ParallelDevicePerformanceProfile(device_configuration, processes_and_threads=[(1, 1), (1, 2), (2, 1)])
 
Best,
Daniele
