A supporting library YHLIB for distributed parallel computing of finite-difference discrete models is studied and proposed, which is implemented using MPI message-passing. YHLIB library encapsulates the implementation technique details of parallel computing and provides many useful User-Interfaces for applications, which support domain decomposition, inter/intra-domain communication, loop-index converting, distributed I/O, load balancing etc. YHLIB is proved to be of considerable high parallel efficiency by abstract model implementation and practical applications test.
