摘　　要：PETSc作为一个典型的通用数值并行软件框架,近年来在诸多领域获得应用。着眼计算流体力学(CFD)领域,研究了PETSc的两个典型开源应用:PETSc-FUN3D和PFLOTRAN,着重分析二者在利用PETSc软件框架方面的方法、思路与效果,评述了PETSc对CFD领域的应用优势及众核异构体系结构对传统并行软件框架技术带来的挑战。Parallel software framework is an important technology that bridging the HPC application model, software to hardware architecture. In recent years, PETSc is applied in many scientific fields as a typical general-purpose numerical parallel software framework. Focusing on the field of computational fluid dynamics（CFD）, this paper studied two famous open- source CFD application baesd on PETSc： PETSc-FUN3D and PFLOTRAN. Both methods and advantages of using PETSc in the two CFD application are summaried. And the challenges of traditional parallel software framework technology which many- core heterogeneous architecture changing brings is discussed.
