Emulating a Paragon XP/S on a Network of Workstations

Networks of workstations are gaining growing importance in high performance computing. Programming environments like MMK/X [Ste93] or PVM [BDG+91] allow for exploiting the aggregate computational power of coupled workstations. A different approach is to use such local area networks as a development platform for parallel applications which should finally run on multicomputer systems. Therefore an environment on the workstations is required which offers the same programming model as the multicomputer system. The work which is presented here describes the NXLib environment which emulates a Paragon system on a network of workstations.
