Using DSP and GPU runtime

Dear Qcom team,

Is it possible to use both DSP and GPU runtime for a single SNPE instance? Or we need to create two instances to reuse full computing power of QCS605?

Thanks and regards,

CDQ

Hi caoducquan,

When a SNPE instance is created, you need to choose the runtime to run the model. Thus, you need to create two instances to use both GPU and DSP.

Thanks,

Thanks for your promptly reply. It means the SNPE library is thread-safe and we can create as many SNPE instance as we need?

Hi caoducquan,

Yes, you can create multiple SNPE instances and run them simultaneosly. But if the instances use same runtime, speed performance drop might happen.

Thanks,
