Rsim: Simulating
Shared-Memory
Multiprocessors
with ILP Processors
G
iven the complexity and associated cost
of building modern computer systems,
simulation is often the only practical way
to test architectural ideas and assess sys-
tem performance. Simulators provide the
flexibility to modify and analyze the impact of var-
ious architectural parameters and components as
well as enable more detailed statistics collection
than real hardware. These benefits make simula-
tion useful even for projects that will eventually
implement hardware.
Prior to 1994, most academic shared-memory
multiprocessor studies largely ignored the processor
model, focusing instead on the memory system as
