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 ... The GLSL defines a number of predefined variablesat the various shader stages. These pre-defined variables are defined with a particular set of qualifiers, as stated in the above article. If you wish to use pre-defined variables with a different qualifier, you can re-declare the variable, but the re-declaration must use … See more There are a large number of layout qualifiers which can be applied to a variety of defined constructs, from interface blocksto shader stage inputs and outputs. These affect the storage location of their data and many other … See more There is a way to qualify certain output variables as being invariant. This allows different programs to compute the exact same answer, assuming certain conditions are met.

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). WebApr 9, 2024 · My read on this is that to emulate the GLSL coherent buffer qualifier, all loads and stores (ie through array indexing) should be translated into atomic load and store functions in Metal. The OpenGL way on this is to annotate the buffer with memory semantics and leave operations unchanged, but a more explicit approach is to annotate the ...

WebJul 1, 2009 · Also, if real branching is done on all gpu cores at the same instruction (coherent branching), it only takes 2 gpu cycles. Coherent branching is obviously guaranteed if you loop uniform_N times. The slowness with uniform-looping comes mostly from the extra loop-preparation instructions that compilers still don’t optimize well enough.
