An abstract semantics of speculative execution for reasoning about security vulnerabilities
Robert J. Colvin, Kirsten Winter
Reasoning about correctness and security of software is increasingly difficult due to the complexity of modern microarchitectural features such as out-of-order execution. A class o…
Correctness of Concurrent Objects under Weak Memory Models
Graeme Smith, Kirsten Winter, Robert J. Colvin
In this paper we develop a theory for correctness of concurrent objects under weak memory models. Central to our definitions is the concept of observations which determine when eff…
A sound and complete definition of linearizability on weak memory models
Graeme Smith, Kirsten Winter, Robert J. Colvin
Linearizability is a widely accepted notion of correctness for concurrent objects. Recent research has investigated redefining linearizability for particular hardware weak memory m…
A synchronous program algebra: a basis for reasoning about shared-memory and event-based concurrency
Ian J. Hayes, Larissa A. Meinicke, Kirsten Winter +1
This research started with an algebra for reasoning about rely/guarantee concurrency for a shared memory model. The approach taken led to a more abstract algebra of atomic steps, i…
