Efficient Parallel Computing and Performance Tuning for Multi-Block Structured Grid CFD Applications on Tianhe Supercomputer
摘要
Abstract
How to improve the parallel performance of CFD applications with typical multi-block structured grid based on the CPU sub-platform of Tianhe-1A and CPU+MIC co-processor heterogeneous platform of Tianhe-2 supercomputer system ,is focused in this paper .Some strategies of performance optimization matched with both the characteristic of CFD application and the architec-tures of high-performance computing (HPC) platform are discussed in detail .Some numerical experiments are performed on Tianhe-2 supercomputer system with the maximum of grid cells achieving 6.8 × 1011 ,and the total amount of processors and/or co-proces-sors being 1.376 × 106 .It shows that the optimized code can get a speedup of 2.6 times faster on CPU and co-processor hybrid plat-form than that on the CPU platform only ,and good scalability is also observed from the test results .关键词
