Some Improved Message Passing Interfaces:PVMPI,IMPI and FT-MPI
若干发展的消息传递界面：PVMPI，IMPI与FT—MPI

Some improved message passing interfaces such as PVMPI.IMPI, in which different MPI implementations in a heterogeneous environment can interoperate with each other. and FT-MPI, which have fault tolerant capability, are introduced, then the feathers and architectures of these MPI are analyzed, the performance are also discussed. All these might provide researchers with reference.
