Please provide the following info:
Hardware Platform: DRIVE AGX Xavier™ Developer Kit
Software Version: DRIVE Software 10
Host Machine Version: native Ubuntu 18.04

When I run “nproc” command, I got the result of only 2 processing units available. While all 6 cores are online.
I checked this topic about RoadRunner from here, but it’s not my case.
Searched for several days, not found the solution yet.
Does anyone know how to check/fix this problem?

Thanks & BRs,

Dear @v.toanlm4,
Could you share the complete used command?
Do you notice the same after fresh DRIVE SW installation?

Dear @SivaRamaKrishnaNV:
I’m sorry, what do you mean “complete used command”?
Here are what I used to check:

nvidia@agx2b:/usr$ nproc --all → check number of online processors
6
nvidia@agx2b:/usr$ nproc → check number of processing unit available
2
nvidia@agx2b:/usr$ sudo systemctl disable rr-launch.timer → try to disable roadruner timer
Failed to disable unit: Unit file rr-launch.timer does not exist.

Thanks,
Toan Le

Dear @v.toanlm4,
I notice the below on my board with DRIVE SW 10.0

nvidia@tegra-ubuntu:~$ nproc --all
6
nvidia@tegra-ubuntu:~$ nproc 
6

Could you please check re-flashing?

@SivaRamaKrishnaNV: I re-flashed the kit. Now it’s 6 already. Thanks.
