In this paper, we describe the design and implementation of a portable run-time system for GOP, a graph-oriented programming framework aiming at providing high-bevel abstractions for configuring and programming cooperative parallel processes. The runtime system provides an interface with a library of programming primitives to the low-level facilities required to support graph-oriented communications and synchronization. The implementation is on top of the Parallel Virtual Machine (PVM) in a local area network of Sun workstations. Issues related to the implementation of graph operations in a distributed environment are discussed. Performance of the runtime system is evaluated by estimating the overheads associated with using GOP primitives as opposed to PVM
