Abstract :
With the advent of 64 bit computer systems, virtual address spaces
with 64 bit addresses become available. This brings in a number of
opportunities as well as a number of problems to handle. One solution
is to have a single virtual address space for all processes and the
operating system kernel in a system. This talk gives an overview of
the research going on in the building of single address space systems.
The savings in context switch time as well as in page table management
overhead are highlighted. The opportunities of handling file storage
differently is discussed. This leads to the easy implementation of
persistent objects. The difficulties, particularly that of
reprogramming existing applications and of grabage collection, are
also discussed.
