WebTo generate random numbers, a kernel can be launched with any con guration of threads and blocks since parallelization is done at the thread level. Disadvantage: If it is desired to improve the speed, then there is a substantial amount of memory sacri ce in doing so. Spade Random Number Generation in Parallel WebS3L_rand_fib initializes a parallel array using a Lagged-Fibonacci random number generator (LFG). The LFG's parameters are fixed to l = 17, k = 5, and m = 32. Random numbers are produced by the following iterative equation: x [n] = (x [n-e] + x [n-k]) mod 2 m The result of S3L_rand_fib depends on how the parallel array a is distributed.
