Thanks Damjan . l was trying that because I want to move threads to other
partition.At the system start if main core is associated with some control
core group worker thread inherits this from parent thread and later set
affinity fails if you try to move worker thread to different partition.
Hence wanted to explore pthread with dpdk .is there any way where we can
specify worker thread group association ?

Bindiya
