slower when change DefaultDeviceType from GPU to DLA?

JinglinYuan · March 22, 2019, 8:36am

I cloned the repo GitHub - dusty-nv/jetson-inference: Hello AI World guide to deploying deep-learning inference networks and deep vision primitives with TensorRT and NVIDIA Jetson. for object detection on Jetson Xavier.
The network I used is DetectNet.
The engine is run on GPU by default, so I wanted to try run inference on DLA.
I modified some default parameters for function DetectNet::create() in the file named detectNet.h:
2 to 1 for “maxBatchSize” and DEVICE_GPU to DEVICE_DLA_0 for “device”.

But it seemed that the speed become slower.
for DLA:[TRT] layer network time - 44.175682 ms
for GPU:[TRT] layer network time - 10.079423 ms

And blow is the detailed information:

On line 74 in DLA information: [TRT] layer bboxes from nvm - 41.842625 ms
Seems that this layer wasted most time in inference, but I can’t understand why.

Hi,

Could you help to generate the DLA log from tensorrt app first?

$ cp -r /usr/src/tensorrt/ .
$ cd tensorrt/samples/trtexec/
$ make
$ cd ../../bin/

./trtexec --deploy=[your mode]
./trtexec --deploy=[your mode] --useDLACore=0 -allowGPUFallback

Thanks.
