Need a bit more information on Intel openvino -nstreams flag

I am currently researching and experimenting a lot with Intel OpenVINO toolkit. Amazing toolkit, to be fair. But the -nstreams flag is confusing me a lot. In the code flag description it says "Number of streams to use for inference on the CPU or/and GPU in throughput". 

My question is, what does it actually mean? Is it the number of video stream input or the number of camera devices connected? Or is it related to something else?

I have gone through almost all of the documentation online but could not find much clear information on it.

I might be missing something obvious here, but if anyone can clarify this, then it would be a lot helpful.

Hi,


Generally, the -nstreams "<integer>" command is a part of CPU performance option in OpenVINO.

This meant for defining the number of streams to be used for inference on the CPU, GPU or MYRIAD devices


It's OPTIONAL and usually, the automatic selection is used. (Default value is determined automatically for a device).


Try to understand the whole concept of this: https://www.youtube.com/watch?v=2G6uSHPFP-Q

Greetings,


Intel will no longer monitor this thread since this issue has been resolved. If you need any additional information from Intel, please submit a new question.
