Description
This extension splits OpControlBarrier by exposing two new barrier
operations with
SPV_EXT_split_barrier:
-
OpControlBarrierArriveEXT- notifies that invocation has arrived here -
OpControlBarrierWaitEXT- waits on all invocations before proceeding execution
In the Vulkan context, this allows apps to synchronize Subgroup execution flow within a Workgroup without requiring all Subgroups to wait at the arrival condition before proceeding to execute independent work. It also permits synchronizing memory access like other control barriers.
