Efficient, general purpose pseudo-random number generation ---------------------------------------------------------- This package provides the System.Random.MWC module, a Haskell library for generating high-quality pseudo-random numbers in a space- and time-efficient way. Performance ----------- This library has been carefully optimised for high performance. To obtain the best runtime efficiency, it is imperative to compile libraries and applications that use this library using a high level of optimisation. Suggested GHC options: -O -fvia-C -funbox-strict-fields To illustrate, here are the times (in seconds) to generate and sum 250 million random Word32 values, on a laptop with a 2.4GHz Core2 Duo P8600 processor, running Fedora 11 and GHC 6.10.3: no flags 200+ -O 1.249 -O -fvia-C 0.991 As the numbers above suggest, compiling without optimisation will yield unacceptable performance.
