Before revision:  The avoidance of any branching statement is of use in optimal GPU computations, and we give example of branch-free normal quantiles that offer performance improvements in a GPU environment, while retaining the precision characteristics of well-known methods  .
After revision:  The avoidance of any branching statement is of use in optimal GPU computations, and we give example of branch-free normal quantiles that offer performance improvements in a GPU environment, while retaining the precision characteristics of well-known methods . Comparisons are made on Nvidia Quadro and GTX 285 and 480 GPU cards .
