Relationships Between Broadcast and Shared Memory in
Reliable Anonymous Distributed Systems

Abstract We study the power of reliable anonymous
distributed systems, where processes do not fail, do not
have identifiers, and run identical programmes. We are
interested specifically in the relative powers of systems
with different communication mechanisms: anonymous
broadcast, read-write registers, or read-write registers
plus additional shared-memory objects. We show that a
system with anonymous broadcast can simulate a system
of shared-memory objects if and only if the objects sat-
isfy a property we call idemdicence; this result holds re-
gardless of whether either system is synchronous or asyn-
chronous. Conversely, the key to simulating anonymous
broadcast in anonymous shared memory is the ability to
count: broadcast can be simulated by an asynchronous
