Abstract
--------
A Network of Workstations (NOW) has become an important distributed
platform for large-scale scientific computations. A practical NOW system
is heterogeneous and nondedicated, where computing power varies among the
workstations and multiple jobs may interact with each other during
execution. In this paper, we present the design and implementation of
a simulation system for a nondedicated heterogeneous NOW. This
simulator provides many options to users to specify and quantify
system architectures, network heterogeneity and time-sharing factors,
such as speeds of different processors, memory organizations, network
topology, communication structures, and workload distributions. The
simulator also supports execution of message-passing parallel programs
written in C and the PVM library. The software structure of the simulator
is well-modularized and highly extensible, which makes it easy to integrate
other existing processor, memory and network simulators.
