Evaluation of Pseudo-Random Number Generation on GPU Cards

open access: yesComputation, 2021
Monte Carlo methods rely on sequences of random numbers to obtain solutions to many problems in science and engineering. In this work, we evaluate the performance of different pseudo-random number generators (PRNGs) of the Curand library on a number of ...

Shifted Sobol points and multigrid Monte Carlo simulation

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2021
Multidimensional integrals arise in many problems of physics. For example, moments of the distribution function in the problems of transport of various particles (photons, neutrons, etc.) are 6-dimensional integrals.

Applying AVX512 vectorization to improve the performance of a random number generator

open access: yesТруды Института системного программирования РАН, 2018
The generation of uniformly distributed random numbers is necessary for computer simulation by Monte Carlo methods and molecular dynamics. Generators of pseudo-random numbers (GPRS) are used to generate random numbers.

Advanced Statistical Testing of Quantum Random Number Generators

open access: yesEntropy, 2018
Pseudo-random number generators are widely used in many branches of science, mainly in applications related to Monte Carlo methods, although they are deterministic in design and, therefore, unsuitable for tackling fundamental problems in security and ...

Comparing Halton and Sobol Sequences in Integral Evaluation

open access: yesZanco Journal of Pure and Applied Sciences, 2019
Halton and Sobol sequences are two of the most popular number sets used in quasi-Monte Carlo methods. These sequences are effectively used instead of pseudo random numbers in the evaluation of integrals.

Placental Blood-Flow Velocity Quantification From Diffusion MRI. [PDF]

open access: yesMagn Reson Med
ABSTRACT Purpose Altered placental capillary blood flow is closely linked to obstetric complications, yet quantifying capillary‐scale blood velocity remains challenging with existing imaging methods. This is partially because capillary networks form disordered microvascular beds at the voxel scale, rather than coherent, directional vessels.

A comparative analysis on computational methods for fitting an ERGM to biological network data [PDF]

open access: yesNetwork Biology, 2015
Exponential random graph models (ERGM) based on graph theory are useful in studying global biological network structure using its local properties. However, computational methods for fitting such models are sensitive to the type, structure and the number

Research on Random Discrete Ordinates Method Based on Quasi-Monte Carlo Integration Technique

open access: yesYuanzineng kexue jishu
The discrete ordinates (SN) method proposed by Carlson constitutes an angular discretization for neutron transport equation. Owing to its superior computational accuracy and efficiency compared to alternative numerical approaches, the SN method has been ...
