“…Because the techniques used to parallelize a single MD simulation have already been surveyed by several authors, 13,14 we will provide here only a brief summary of some of the salient characteristics of the three major categories of traditional approaches to this problem: (a) atom decomposition methods, (b) force decomposition methods, and (c) spatial decomposition methods.…”

“…Starting from the models requiring 27 (3x3x3 set) processors or more, each processor should generally exchange messages with its 26 neighbors. Since interprocessor communication is relatively slow operation, it is more advantageous to implement the three-stage updating procedure [12] where only three pairs of exchanges are required ( Figure 3).…”

“…Totally 3 pairs of exchanges are needed. Adopted from [12]. It should be noted that the usage of blocking SendRecv routines of MPI library to exchange data at stage 4 plays a very important role in general synchronization of the computations over the processors set.…”

“…Several attempts have been made to parallelize Monte Carlo algorithms through system decomposition into a number of noninteracting domains. 4,5 Updating a molecule with interaction range beyond its own domain needs the most up-to-date information of its neighbor molecules from logically adjacent computers. In parallel simulations on distributed computers/clusters, communication between processors is a much slower process due to the limit of network speed and data traffic, compared with ultrafast local cache or memory operation.…”

“…The violation of strict detailed balance causes concerns about the precision of this type of parallel Monte Carlo simulation. 5 Most Monte Carlo simulations ensure strict detailed balance via random updating. Recently, we proposed a Monte Carlo algorithm based on sequential updating moves with partial randomness that only satisfies the weaker balance condition.…”
