groupMemoryBarrier — controls the ordering of memory transaction issued shader invocation relative to a work group
groupMemoryBarrier waits on the completion of all memory accesses performed
by an invocation of a compute shader relative to the same access performed by other invocations
in the same work group and then returns with no other effect.
