Summary: Incorporate MIXMAX random number extension into GSL Project: GNU Scientific Library Submitted by: psa Submitted on: Tue 09 Feb 2021 04:09:05 AM UTC Category: None Severity: 3 - Normal Operating System: Status: None Assigned to: None Open/Closed: Open Release: Discussion Lock: Any _______________________________________________________ Details: from savvidy =at= inp =dot= demokritos =dot= gr We have news on MIXMAX PRNG. 1.It was fully implemented at CERN into the CLHEP/Geant4 software a toolkit for the simulation of the passage of particles through matter as default generator: https://proj-clhep.web.cern.ch/proj-clhep/ (see Notes) 2.Became a part of the CMS Simulation Software at CERN: https://indico.cern.ch/event/731433/contributions/3015654/attachments/1680131/2698971/CMSsim.pdf (see Pages 13-17) https://indico.cern.ch/event/587955/contributions/2937635/attachments/1679273/2706817/PosterCMS_SIM_v4.pdf 3.It was recently used by NASA in their design of the new mission to the Sun with the neutrino telescope - a Solar Neutrino Spacecraft - the article is attached (see page 13) The authors of this project stated that: " Early in this project, the random number generation functions available in standard C++ packages proved unsuitable for use; they produce values which fall into a regular pattern of magnitude and will generally avoid generating numbers very near zero or one. For these reasons, the MIXMAX family of pseudo-random number generators have been utilised here. Based off on Anosov C-systems— a mathematical function group with useful instabilities in their structure— this family of generators allows for the most random numerical output in the shortest computational time [7] ". We think that the problems with C++ packages above were connected with the resolution power of the generators. In a simple terms - the MIXMAX is genuine 64 bit generator and have superior resolution power. Please let me know if there were questions regarding MIXMAX. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?60026> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
