The MPI-Delphi Interface: A Visual Programming Environment for Cluster of Workstations

The goal of a parallel program is stated as to reduce the execution time regarding the fastest sequential program solving the same problem. Parallel programming is growing due to the widespread use of network of workstations in high performance computing. MPI has become the standard for implementing message-based parallel programs in distributed-memory computing environments. On the other side, visual programming environments try to make easier the task of developing applications. Delphi constitutes one of the most popular visual programming environments nowadays in the Windows operating system environment. In this paper we present MPI-Delphi, an implementation of MPI for writing parallel applications using Delphi. We explain how MPI-Delphi has been derived, how it has been used in a cluster of workstations with a mixed of Windows and Linux operating systems, and what MPI-Delphi is suitable for.
