Microarchitectural vulnerabilities, such as Meltdown and Spectre, exploit subtle
microarchitecture state to steal the user's secret data and even compromise the operating …

Computer architects employ a series of performance optimizations at the micro-architecture
level. These optimizations are meant to be invisible to the programmer but they are implicitly …

Memory-disk synchronization is a critical technology for ensuring data correctness, integrity,
and security, especially in systems that handle sensitive information like financial …

Since the discovery of the Spectre and Meltdown vulnerabilities, transient execution attacks
have increasingly gained momentum. However, while the community has investigated …

Modern x86 processors have many prefetch instructions that can be used by programmers
to boost performance. However, these instructions may also cause security problems. In …

This paper presents the first comprehensive analysis of contention-based security
vulnerabilities in a high-performance simultaneous mulithreaded (SMT) processor. It …

The deep learning revolution has been enabled in large part by GPUs, and more recently
accelerators, which make it possible to carry out computationally demanding training and …

Microarchitectural side channels are a pressing security threat. These channels are created
when programs modulate hardware resources in a secret data-dependent fashion. They are …

There is a constant evolution of technology for cloud environments, including the
development of new memory storage technology, such as persistent memory. The newly …

Cache partitioning is a principled defense against side-channel attacks on shared last-level
caches (LLCs). Such defenses allocate isolated cache regions to distrusting applications …
