| Horizon68 <horizon@horizon.com>: Oct 27 10:43AM -0700 Hello.. About my Good random number generators and scalability.. I think my mersenne and splitmix64 random generators can work with multiple threads and can be "scalable", look at at ThreadedRandomizedSeed() method to obtain a random seed: == function TMersenne.ThreadedRandomizedSeed():longword; var a:double; begin if bool1=false then begin bool1:=true; a:=sin(GetCurrentThreadId)*high(longword); if a < 0 then a:=-a; if not assigned(mersenne1) then mersenne1:=TMersenne.create; mersenne1.initialize(round(a)); result:=mersenne1.urand; end else result:=mersenne1.urand; end; == You can create a mersenne or splitmix64 object for every thread and initialize in each thread with ThreadedRandomizedSeed(), and after than get your random number in each thread, i think this way is "scalable". My Good random number generators for Delphi and FreePascal was updated to version 1.01, you can port them to C++.. Look at them they are powerful. Author: Amine Moulay Ramdane that has enhanced both random number generators. Description: This is an enhanced versions of both Mersenne Twister that is a good random number generator and Splitmix64 that is a fast random number generator, both have passed the BigCrush tests. Look into defines.inc file, there is many options: {$DEFINE CPU32} and {$DEFINE Windows32} for 32 bit systems {$DEFINE CPU64} and {$DEFINE Windows64} for 64 bit systems Look at test.pas demo inside the zip file... You can download it from: https://sites.google.com/site/scalable68/good-random-number-generators Language: FPC Pascal v2.2.0+ / Delphi 5+: http://www.freepascal.org/ Operating Systems: Win , Linux and Mac (x86). Required FPC switches: -O3 -Sd -Sd for delphi mode.... Required Delphi switches: -$O+ Thank you, Amine Moulay Ramdane. |
