  Many-core architectures of the future are likely to have distributed memory
organizations and need fine grained concurrency management to be used
effectively. The Self-adaptive Virtual Processor (SVP) is an abstract
concurrent programming model which can provide this, but the model and its
current implementations assume a single address space shared memory. We
investigate and extend SVP to handle distributed environments, and discuss a
prototype SVP implementation which transparently supports execution on
heterogeneous distributed memory clusters over TCP/IP connections, while
retaining the original SVP programming model.
