- W2352364139 abstract "The performance and scalability evaluation of the large scale simulation software on planetary fluid dynamics are investigated by the experiments on the domestic 100 TFlops supercomputer,Dawning 5000A.The details of the software testing procedures,the environment and the process of the testing are introduced.For the mesh size of 80×80×50,the performance testing on 16 to 128 processor cores with mapping 4 processes on each node and the performance testing on 16 to 512 processor cores with mapping 16 or 8 processes on each node are performed,respectively.The relative speedups reach 5.33,10.48 and 12.57,respectively,and the corresponding parallel efficiencies of these 3 testing cases are 66.66%,32.58% and 32.29%,respectively.For the mesh size of 160×160×100,the performance testing on 64 to 8 192 processor cores with mapping 16 processes on each node gives the results that the relative speedup is 12.46,and its parallel efficiency is 9.73%.The experimental results reveal the good performance of Dawning 5000A and show important clues of the software optimization." @default.
