Abstract
This paper describes the design and implementation of a distributed
shared memory facility we have implemented for the FreeBSD operating
system (a descendant of 4.4BSD that runs on the PC architecture).
Interesting aspects of the design are:
(1) the consistency protocol uses unreliable datagram communication,
but is robust with respect to message loss, and in the normal case requires
only two datagrams to handle a read fault;
(2) the facility provides a simple programming interface that does not
require any socket or network programming to use;
(3) the facility extends the FreeBSD VM system in a very non-intrusive way.
