Hi Shreyansh,    I think it can skip the message since you only have 1 numa node in your platform. And from your log, the print out should be came out from your application, right?hello from core 1hello from core 2hello from core 3hello from core 0    If there is any init failed, the print out will not came out.  Thanks,Marco
