Abstract
We present some results conceming computational performances of the open source CFD software PalaBos, in terms of scalability and efficiency, on the petascale Sunway BlueLight MPP system. Based on the numerical simulated program of 3D cavity lid driven flow, the optimization methods in I/O, communication, memory access, etc, are applied in debugging and optimization of the parallel MPI program. Experimental results of large scalar parallel computing of 3D cavity lid driven flow show that, the parallel strategy and optimization methods are correct and efficient. The parallel implementation scheme is very useful and can shorten the computing time explicitly.
