TP600 Priorities for Touchscreen and OPCUA

[Barron]

Hello all,
In using multicore with the 762-5305/8000-002 I have found that on occasion, the core where a high priority task utilized for ModbusFB is occasionally pegged out. At the time this occurred at core 3 (linux core 2). I have since moved this task to another core and I have not had this issue since. I wondered if this was caused by a conflict in the OPCUA functionality.

I also had an instance where I distributed task across all four cores and the visualization would no longer load. In my testing, none of my task priorities were below 10.

I am curious if there is a linux command prompt command where I could view particular hardware/software functions and at what core they are residing on at a given time, or if there are any further details on this topic than what is attached.

Thank you,
Barron

Maybe you can use htop command to see the process and on which core they are running.
To configure htop, press F2.
Check Display option / Tree view for a structured view.
Check Columns / Processor to see the CPU ID

You can know see the CPU ID

Thank you Quentin,
I’ve used htop to monitor cpu load, but not to narrow down processes. I appreciate the support.

Would you say the OPCUA and touchscreen functions are managed by Linux and distributed across all cores? Or are they static to one core?
