Matrix multiplication and universal scalability of the time on the Intel Scalable processors
Alexander Russkov, Lev Shchur
Matrix multiplication is one of the core operations in many areas of scientific computing. We present the results of the experiments with the matrix multiplication of the big size…
Variable-step-length algorithms for a random walk: hitting probability and computation performance
Olga Klimenkova, Anton Yu. Menshutin, Lev N. Shchur
We present a comparative study of several algorithms for an in-plane random walk with a variable step. The goal is to check the efficiency of the algorithm in the case where the ra…
On properties of the Wang--Landau algorithm
L. N. Shchur
We review recent advances in the analysis of the Wang--Landau algorithm, which is designed for the direct Monte Carlo estimation of the density of states (DOS). In the case of a di…
Estimating the Density of States of Frustrated Spin Systems
Lev Barash, Jeffrey Marshall, Martin Weigel +1
Estimating the density of states of systems with rugged free energy landscapes is a notoriously difficult task of the utmost importance in many areas of physics ranging from spin g…
Synchronization of Conservative Parallel Discrete Event Simulations on a Small-World Network
Liliia Ziganurova, Lev N. Shchur
We examine the question of the influence of sparse long-range communications on the synchronization in parallel discrete event simulations (PDES). We build a model of the evolution…
Influence of the random walk finite step on the first-passage probability
Olga Klimenkova, Anton Menshutin, Lev N. Shchur
A well known connection between first-passage probability of random walk and distribution of electrical potential described by Laplace equation is studied. We simulate random walk…
On the mixing time in the Wang-Landau algorithm
Marina Fadeeva, Lev N. Shchur
We present preliminary results of the investigation of the properties of the Markov random walk in the energy space generated by the Wang-Landau probability. We build transition ma…
Control of accuracy in the Wang-Landau algorithm
L. Yu. Barash, M. A. Fadeeva, L. N. Shchur
The Wang-Landau (WL) algorithm has been widely used for simulations in many areas of physics. Our analysis of the WL algorithm explains its properties and shows that the difference…
Morphological diagram of diffusion driven aggregate growth in plane: competition of anisotropy and adhesion
Anton Yu. Menshutin, Lev. N. Shchur
Two-dimensional structures grown with Witten and Sander algorithm are investigated. We analyze clusters grown off-lattice and clusters grown with antenna method with $N_{fp}=3,4,5,…
