Abstract :
In this paper, issues related to implementing an MPI version of the Basic Linear Communication Subprograms (BLACS) are investigated. A set of routines, the MPI Linear Algebra Communication Subprograms (MLACS), are presented, and these are used to implement an MPI version of the BLACS. The MLACS provide the same functionality as the BLACS, but extend the functionality of the BLACS to include both blocking and nonblocking communication, and all four of the MPI communication modes
