Abstract :
The implementations of ABCL (an object-based concurrent language) on two different types of multicomputers-Electrotechnical Laboratories´ EM-4 extended dataflow computer, and Fujitsu´s experimental AP1000-are described. ABCL/EM-4 takes advantage of that machine´s packet-driven architecture to achieve very good preliminary performance results. The AP1000 does not have special hardware support for message passing, so ABCL/AP1000 includes several software technologies that are general enough for conventional parallel or concurrent languages, again yielding promising performance. It is concluded that the results demonstrate the viability of attaining good performance with concurrent object-oriented languages on current multicomputers, whether experimental or commercial.<>
