Webcoherent Memory accesses are done with similar accesses from other shader threads. When reading a variable declared as "coherent", the values returned will reflect the results of previously completed writes by other shader threads. Note that Shader memory reads and writes complete in a largely undefined order (see memory barriers). WebDescription. atomicMax performs an atomic comparison of data to the contents of mem, writes the maximum value into mem and returns the original contents of mem from before the comparison occured. The contents of the memory being updated by the atomic operation are guaranteed not to be modified by any other assignment or atomic memory function ...
