GCN: local memory barrier and work group size

Question asked by boxerab on Aug 22, 2015
Latest reply on Dec 19, 2016 by boxerab

I have a kernel with work group size equal to half wave front (64), running on GCN arch.

Can I dispense with local memory barriers for this kernel?

I realize that this may not work for future micro-archs, but for GCN arch up to and including Fury,

is this advisable to remove barriers?
