For users who want a pseudorandom number generator that is portable across parallel machines, we supply hooks in the MPI and CM-5 code to use the additive lagged-Fibonacci generator described in [6]. This is available to US residents via FTP from ftp://ftp.super.org/pub/mascagni/lfibrng6a.tar.Z. See the appropriate CVL Makefile for instructions on how to enable the hooks.
