In order to apply our high efficiency fibre-channel token-routing network(shortened as FC-TR network) to the field of materials simulation research, a new mpiparallel computing environment is proposed and designed, and independently developed a parallel programming environment FC-TR-mpi based on FC-TR network. In FC-TR-mpi, a new method was applied to point-to-point communication that the network communications between processes in the same computing node were changed into memory operations;moreover, according to the underlying software and hardware features of FC-TR network, new algorithms were proposed to optimize the communication performance of some collective communications. Experimental results show that, compared with Sca mpiparallel programming environment, FC-TR-mpi has a higher parallel efficiency and speedup.
