Dear all,
Any hints on how can I get some stats on the GPU usage (similar to nvidia-smi) on the TX1 ?
Would love to have some nice stats to benchmark some neural simulations.
Cheers,
Cristian
Try running ~/tegrastats and look for GR3D:
sudo ~/tegrastats
[sudo] password for ubuntu:

Excellent, thanks Dustin !
The last columns are suppressed if not running as super user. Briefly, what are the AVP, VDE, and GR3D fields ?
Thanks,
Cristian
Don’t bother, found it in a previous forum post :)
EMC – memory controller
AVP – audio/video processor
VDE – video decoder engine
GR3D – GPU
Cheers,

I’m also interested in monitoring the GPU usage on the TX1.
How should I interpret the GR3D field? Its in the form xx%@yy.
I assume xx is the percentage of GPU load, but what does yy tell?

Thanks,

These are linked to devices frequencies. You can get the details of it with
sudo ~/jetson_clocks.sh --show
tegrastats shows GPU load percentage and total clock rate, but how do I see the GPU memory utilization, or how do I monitor the GPU memory?
On Jetson, the same memory is shared by CPUs and GPU.
Of course, my bad. I wanted info about the Drive PX2 I’m working on, which has Tegra X2s, and discrete GPUs. The s/w package for it uses the same tooling as the Jetson, including tegrastats.
Hi ,

Me trying to get the performance numbers and GPU utilization for H.265 encoding using hardware accelerators on Tegra Tx2 Board.
1.a) I am getting MSENC number how to related % utilization of hardware accelerators ? below is the snap of output.
1.b) Command for encoding {./video_encode COSTARICA4k.yuv 3840 2160 H265 out1.h265 -rc vbr -br 10000000 -fps 30 1}
1.c) Command for checking resource utilization.

In the sample example code , Their is two encoders one is "01_video_encode" and other is 03_video_cuda_enc?
2.a) what is the difference ?
2.b) which one uses cuda core and hardware accelerators (NVENC)?
{both code looks similar just 01_video_encode has more option for configuration } -
MSENC for h.264 is showing MSENC only ? which means hardware accelerators for H.264 is MSENC (dedicated hardware chip)
