Hi ,
I am using AGX Drive XAVIER platform for our autonomous project .
Currently , i am running Lidar , Radar and single camera on the target along with RVIZ .
I found performance reduced to less than 2 Fps when i run all 4 module together .
not only object detection performance but overall system runs very slow .
There is a sufficient RAM space is available on target around 18 GB and CPU also under utilized for the same .
I was trying to check PowerMizer setting and found it shows only “AC” .
Why it runs very slow despite of having enough free resource bandwidth ?
It sounds like you’re experiencing a performance bottleneck on your AGX Xavier platform when running multiple modules simultaneously. While it’s good to have enough RAM and CPU resources available, it’s also important to consider the available GPU resources for each module.
Have you checked the GPU utilization when running all four modules together? You can use the Nsight Systems tool. Nsight Systems provides a graphical interface that shows GPU utilization, memory usage, and other performance metrics.
Can you please clarify what did you expect to see when checking PowerMizer setting? Also, did you check it on the devkit? If so, how did you check it?
Trying to setup nsight tool as well. current softwares are not Compute intensive therefore i would like to know is there any way to increase performance of system . i mean like nvpmodel type of command on system.
DRIVE OS doesn’t support different power modes. In the meantime, you can monitor the resource utilization using tegrastats as you set up nsight systems.
Thanks for response
Below are the Tegrastats log

I have a few doubts regarding core uses. We have an octa-core processor, but in the logs it is only showing 6 cores. Another observation is that it always uses Core 1, 2, 3, and 6.
There are several existing forum topics that discuss this, e.g. Only 4 cores out of 6 are available on Pegasus. I recommend searching the forum using relevant keywords to find the information you are looking for. This will allow you to access detailed discussions and insights shared by the community.
I have gone through the link but am not getting a clear answer to the underutilization of the system. Can you share any official document link for the same?
Please refer to DRIVE OS Linux. Thanks.
