WebJun 19, 2024 · Atomic counters don't exist in Vulkan, so you'll have to go with one of those solutions. BTW, atomic counters, as a distinct hardware concept, are only something … WebVulkan only requires invocations to reconverge after the if statement that performs the subgroup election if all the invocations in the workgroup are converged at that if statement. If the invocations don’t reconverge then the broadcast and offset calculations will be incorrect. ... base = atomicAdd(b.free, size); } // Broadcast the base ... WebExplanation. SMyBuffer is a stack of elements ( data []) with a count of the current number of elements. When a certain condition is met, the compute shader increments the count atomically. This operation returns the previous index which is used to index data [] to store the new element. This guarantees that no two shader invocations overwrite ... britain\u0027s got talent wikipedia
