Editing Predication (computer architecture) (section)

== SIMD, SIMT and vector predication ==

Some [[SIMD]] instruction sets, like AVX2, have the ability to use a logical [[Mask (computing)|mask]] to conditionally load/store values to memory, a parallel form of the conditional move, and may also apply individual mask bits to individual arithmetic units executing a parallel operation.  The technique [[Flynn's taxonomy#Associative processor|is known in Flynn's taxonomy as "associative processing"]].

This form of predication is also used in [[vector processors]] and [[single instruction, multiple threads]] GPU computing.  All the techniques, advantages and disadvantages of single scalar predication apply just as well to the parallel processing case.
