Hello Experts,

Curious to know that the tensorrt SDK will use GPU alone or mix of CPU + GPU to run the inference and other functionalities.
Not sure, but AFAIK it would mainly use GPU, and maybe DLA on Xavier as well.
Someone more skilled with this topic may better advise.
Hi,
As Honey_Patouceul said, TensorRT mainly use GPU for inference.
On Xavier, TensorRT also supports DLA inference.
Thanks.
Hi,
You can get the layer-level profiling data directly with our trtexec app with --dumpProfile flag.
For example, here is the output from YOLOv3 Tiny model:
/usr/src/tensorrt/bin/trtexec [your/model/info] --dumpProfile
...
