In this work, we discuss the Automatic Adjoint Differentiation (AAD) for functions of the form G=(1)/(2)∑1m (Eyi-Ci)2, which often appear in the calibration of stochastic models. We demonstrate that it allows a perfect SIMD\footnoteSingle Input Multiple Data parallelization and provide its relative computational cost. In addition we demonstrate that this theoretical result is in concordance with numeric experiments.
