Mobility of Data in Distributed Hybrid Computing Systems

In distributed hybrid computing systems, traditional sequential processors are loosely coupled with reconfigurable hardware for optimal performance. This loose coupling proves to be a communication challenge; the processor units cannot efficiently share a physical memory. This paper proposes a distributed shared memory architecture and a method for effective data migration within that shared memory. Data is moved using a novel garbage collection scheme, the dual semispace collector. The new garbage collector and the distributed memory prove to be an effective means of data migration in distributed hybrid computing systems.
