| It is recognised that the availability of a large number of workstations connected through a network can represent an attractive option for many organisations to provide to application programmersan alternative environment for high-performance computing. The original specification of the Message-Passing Interface (MPI) standard was not designed as a comprehensive parallel programming environment and some researchers agree that the standard should be preserved as simple and clean as possible.Nevertheless, a software environment such as MPI should have somehow a scheduling mechanism for the effective submission of parallel applications on network of workstations. This paper presents the performance results and benefits of an alternative lightweight approach called {\it Selective - MPI} (S-MPI), which was designed to enhance the efficiency of the scheduling of applications on parallel workstation cluster environments. |
