摘　　要：As the parallel version of LAPACK, ScaLAPACK will provide convenient and powerful parallel programming platform for parallel computing society. In this paper, wepropose a PVM based ScaLAPACK application programming structure. Based on thisgeneral programming structure, we give three initialization methods of BLACS thatcan be used under different situations. The data distribution fashion used in ScaLAPACK is also introduced to help the user to understand them better. For those whoare familiar with PVM parallel programming, they can call ScaLAPACK subroutinesdirectly using our methods, without concerning ScaLAPACK details too much. Finally,several shortcomings of current version ScaLAPACK package are discussed and an APIis proposed to improve its usability.As the parallel version of LAPACK, ScaLAPACK will provide convenient and powerful parallel programming platform for parallel computing society.
