Parallel task limit issue on 80 core (2 CPU) system

cbl — Thu, 29 Aug 2024 06:53:07 GMT

Hello,

I have a system with 2 CPU 80 Core 256 GB RAM.

I am starting the Yocto build process with this system.

I set the necessary variables in the local.conf file. The variables I set are as follows.

BB_NUMBER_THREADS = "80"

BB_NUMBER_PARSE_THREADS = "80"

PARALLEL_MAKE = "-j 80"

PARALLEL_MAKEINST = "-j 80"

Despite this configuration, the number of compiled tasks cannot exceed 52. I wonder what is the reason for this?

Could you please support me on this issue?

Best regards.

After change local.conf, move to Yocto base dir and run command source setup-environment ./your_build_folder
