DISTRIBUTED SYSTEMS SEMINAR
- Thursday, March 30, 1989
Mr. Willard Korfhage, of the Department of Computer
Science, University of California at Los Angeles, will
speak on ``Collecting Unused Processing Capacity: An
Analysis of Transient Distributed Systems''.
TIME: 3:30 PM
ROOM: DC 1304
ABSTRACT
Networks of computers are fairly common in business and
research environments throughout the world. Originally
motivated by a desire to ease data and device sharing,
many networks have grown in speed and sophistication to
the point that distributed processing can be performed
on them. A typical example is that of workstations on a
high-speed, local area network in a research
laboratory. Not only are there many machines, well
connected by the network, but the users are likely to
demand more and more computing power.
On these networks, we often have the situation that
many of the personal computers and workstations are
sitting idle, waiting for their users, and thus being
wasted. If we could recover this wasted time for useful
processing, then we would have considerable computing
power available to us at low cost. We refer to these
processors, which are sometimes busy and sometimes not,
as transient processors.
In this talk we develop a model of a network of
transient processors. First we examine a program in
isolation, to determine how the use of transient
processors affects its service time, and then we use
this to develop queueing models of the network as a
whole.
