Abstract

The invention provides an acceleration optimization method and system for parallel PME of molecular dynamics simulation software, and the method comprises the steps: a calculation task is divided intoa plurality of parts, the calculation task is distributed to all slave cores of a super calculation platform, and the calculation is carried out through the slave cores; in the fast Fourier transformin the calculation process, data replication of matrix transposition is completed by utilizing data partitioning and a slave core; and the master core obtains the calculation results of the slave cores in a DMA mode, merges and vectorizes the calculation results, and the master core uses an RDMA technology to replace a traditional MPI technology to obtain data of other master cores. According tothe method, the molecular dynamics simulation software can be smoothly loaded on the super computing platform, and meanwhile, the computing performance can be improved.
