Persistent Owicki-Gries reasoning: a program logic for reasoning about persistent programs on Intel-x86

Azalea Raad, Ori Lahav, Viktor Vafeiadis
2020 Proceedings of the ACM on Programming Languages (PACMPL)  
We prove the soundness of POG over the recent Intel-x86 model, which formalises the out-of-order persistence of memory stores and the semantics of the Intel cache line flush instructions.  ...  To address this, we study the verification of NVM programs, and present Persistent Owicki-Gries (POG), the first program logic for reasoning about such programs.  ...  Ori Lahav was supported by the Israel Science Foundation (grant number 5166651), by Len Blavatnik and the Blavatnik Family foundation, and by the Alon Young Faculty Fellowship.  ...

SoK: Hardware Security Support for Trustworthy Execution [article]

Lianying Zhao, He Shuang, Shengjie Xu, Wei Huang, Rongzhen Cui, Pushkar Bettadpur, David Lie
2019 arXiv   pre-print
In recent years, there have emerged many new hardware mechanisms for improving the security of our computer systems.  ...  In this paper, we systematize these approaches through the lens of abstraction. Abstraction is key to computing systems, and the interface between hardware and software contains many abstractions.  ...  TEEs across architectures In light of the importance of TEEs in establishing (the chain of) trust for a computing platform, we review the presence and positioning of TEEs across mainstream architectures  ...

Model-based approach for semantic-driven deployment of containerized applications to support future internet services and architectures

Nenad Petrovic
2019 Serbian Journal of Electrical Engineering  
In this paper, a model-based framework for automated, semantic-driven (re-)deployment of containerized applications is presented, leveraging the synergy of Virtual Network Functions (VNFs) and SDN, tackling  ...  Due to increasing number of connected Internet of Things (IoT) devices, enormous amount of data needs to be transmitted to the Cloud for processing, while the network is becoming Cloud computing's bottleneck  ...  The later also includes scenarios of computation task movement between devices of different computing architectures in IoT systems (x86 and ARM), supporting the scenarios of Edge computing.  ...

A Verification-Based Approach to Memory Fence Insertion in Relaxed Memory Systems [chapter]

Alexander Linden, Pierre Wolper
2011 Lecture Notes in Computer Science  
Specifically, it considers the TSO (Total Store Order) relaxation, which corresponds to the use of store buffers, and its extension x86-TSO, which in addition allows synchronization and lock operations  ...  Its starting point is a program that is correct for the usual sequential consistency memory model, but that might be incorrect under x86-TSO.  ...  In spite of its name, x86-TSO is not an exact model of a given architecture, but is an abstract programmer's model that covers the documented behaviors of a wide range of processors.  ...
