Efficient space virtualisation for Hoshen--Kopelman algorithm (1803.09504v2)

Published 26 Mar 2018 in physics.comp-ph and cs.DC

Abstract: In this paper the efficient space virtualisation for Hoshen--Kopelman algorithm is presented. We observe minimal parallel overhead during computations, due to negligible communication costs. The proposed algorithm is applied for computation of random-site percolation thresholds for four dimensional simple cubic lattice with sites' neighbourhoods containing next-next-nearest neighbours (3NN). The obtained percolation thresholds are $p_C(\text{NN})=0.19680(23)$, $p_C(\text{2NN})=0.08410(23)$, $p_C(\text{3NN})=0.04540(23)$, $p_C(\text{2NN+NN})=0.06180(23)$, $p_C(\text{3NN+NN})=0.04000(23)$, $p_C(\text{3NN+2NN})=0.03310(23)$, $p_C(\text{3NN+2NN+NN})=0.03190(23)$, where 2NN and NN stand for next-nearest neighbours and nearest neighbours, respectively.
