The main problem is that pointers lose their meaning once they are taken out of their address-space. We present a distributed system which has a single address-space encompassing all virtual memory of every node in the system. This design has become possible (and practicable) with the advent of 64-bit microprocessors. In our system, every pointer retains its meaning independent of its location, even across nodes or on secondary storage. No restrictions are imposed on the use of pointers by application programs. Hence persistence is naturally and elegantly integrated into the system. Further features are uniform addressing and unlimited sharing of data, and memory protection based on password capabilities, making the system easy to use. A reliable paging protocol ensures that the impact of node crashes on other parts of the system is minimised."
