8Parallelism and Performance
g05khc is not threaded in any implementation.
The leap-frog method tends to be less efficient than other methods of producing multiple, independent sequences. See the G05 Chapter Introduction for alternative choices.
This example creates three independent sequences using g05khc, after initialization by g05kfc. Five variates from a uniform distribution are then generated from each sequence using g05sac.
