基于NUMECA FINE/Turbo的并行计算测试

为具体了解CFD软件NUMECA FINE/Turbo的并行计算性能,良好把握后续的科研工作进度,分别研究在激活超线程情况下单节点计算与多节点并行计算以及CPU在激活超线程前、后计算速度的差异.结果表明:在多节点并行计算时,计算速度与实际参加并行计算的CPU物理核心数量成正比;在激活超线程的情况下,并行计算节点数在超过实际物理核心数后明显降低计算速度的提升.

Parallel computing test based on NUMECA FINE/Turbo

To understand the parallel computing performance of CFD software NUMECA concretely and have a good grasp of the work progress of the follow up research, the single node computing and the multi node parallel computing are separately researched in the case of activated hyper thread, and the difference of computation speed of the CPU before and after activating hyper thread is obtained. The results show that, the computation speed is proportional to the actual computational number of physical CPU cores in the case of multi node parallel computing; in the case that the hyper thread is activated, the ascension of computation speed is obviously reduced when the number of parallel computing nodes is more than physical cores.
