Parallel strategy of object-oriented finite element parallel computation framework PANDA

LI Yufeng,ZHANG Yalin(Institute of Computer Application,China Academy of Engineering Physics,Mianyang 621900,Sichuan,China)  
To support high performance computation in object-oriented finite element parallel computation framework PANDA,the data structures which are relative to parallel computation are designed in the parts such as computation flow,domain decomposition,partition information,communication encapsulation and so on.The collaborative approach between domain decomposition and parallel solver is established in computation flow,and then three meshing methods are described for domain partition.Due to the good organization of boundary elements and node information of partition with parallel communication encapsulation,the complicated communication invoking becomes simple and feasible.While developing finite element programs,parallel computation service can be obtained by programming in serial codes.An example about clamp indicates that the implementation on parallel computation of PANDA is correct and reliable.
