ANOMALOUS CACHE COHERENCE TRANSACTION DETECTION IN A HETEROGENEOUS SYSTEM

Abstract:

Embodiments for mitigating security vulnerabilities in a heterogeneous computing system are provided. Anomalous cache coherence behavior may be dynamically detected between a host and one or more accelerators using a cache controller at a shared last level cache based upon a pair-based coherence messages functioning as a proxy for indicating one or more security attack protocols.
