In this paper we introduce an implementation of PVM that exploits the homogeneity of a MPP network with user-level task migration. The target machine is the Fujitsu AP3000. It is basically a network of Sun workstations connected by a high-speednetwork. Furthermore, we explore the possibility of allowing the PVM host configuration to expand dynamically so as to include idle nodes into the virtual machine. The result is tmPVM, which allows the virtual machine to re-distribute workload dynamically with low overhead.
