I use Mobilenet on CPU runtime to test performance, and the speed is very slow, about 1.7s to do one time  classification mission.

So i wonder if the CPU runtime just run on one single CPU, can i choose multi thread to speed up the test program?

Hi linnanbryant,

Did you succeed to run your model using SNPE APIs? There is no CPU multi-thread option. The target of SNPE is to run nerual networks fast on Snapdragon GPU/DSP/AIP. As CPU support is just for reference, there is not that much optimization implemented. You'd better use GPU/DSP/AIP runtime on Snapdragon devices.

Thanks,

Jihoon
