Construction And Application Of Cluster Based On MPI And Linux

This thesis introduces the construction and application of PC cluster system based on MPI and Linux.With more and more complex applications of computer, the requirement for the computational speed is increased rapidly. How to meet the need of scientific computation has become one of urgent problems in computer science. The simplest and most effective method is to link PCs together, which constructs a parallel cluster system.In this thesis, we build up a mini cluster system based on MPI and Linux through the study of construction of pallel cluster system, its application and requirement. And we successfully realized transfermation of GeoFEM software in the cluster.The main achievements in this thesis are as follows:(1) Build up a PC cluster system, which is COW style, at lowest cost. The system is built up on Linux and MPICH free software, utilizing PC computer and LAN resources of our Lab, which provides a requisite hardware basis for transferring GeoFEM system.(2) The cluster system has good flexibility and expansibility. The system can provide network services of cluster through the configuration of NFS, NIS, RSH servers. Users can also manage the cluster according to their need. So the design offers a solid basis for the upgrade of computational speed.(3) Hardware resources can get utmost utilizaton. All nodes in our cluster can be used as personal computer when they are not used in parallel calculation, which reveals its flexibility.(4) We successfully finished the GeoFEM installation, debug and run on the cluster. Through the analysis of GeoFEM using environments which are the compilers of MPI, C, C++, FORTRAN90 and so on , the understanding of GeoFEM installation parameters, we got the installation parameters fitted for this cluster.
