Before revision:  In particular, we consider sampling of the prior predictive distribution for approximate Bayesian computation (ABC), the computation of Bayesian p-values for testing prior weak informativeness, and inference on a computationally challenging econometrics model. Through minor code alterations, we show that SIMD operations can improve the floating point arithmetic performance resulting in up to 6\times improvement in the overall serial algorithm performance.
