The DEcorum file system has three components: the DEcorum protocol exporter (or file server); the Episode physical file system; and the DEcorum client (or cache(More)
Moving the contents of a large virtual address space stands out as the bottleneck in process migration, dominating all other costs and growing with the size of the program. Copy-on-reference shipment is shown to successfully attack this problem in the Accent distributed computing environment. <italic>Logical</italic> memory transfers at migration time with(More)
