Flexible Concurrency Control for Legacy CAD to Construct Collaborative CAD Environment
Journal of Advanced Mechanical Design, Systems and Manufacturing, 2012 Collaborative CAD (Co-CAD) systems can be constructed based on either 3D kernel or legacy stand-alone CAD systems, which are typically commercial CAD systems such as CATIA, Pro/E and so on.

Concurrency and Privacy with Payment-Channel Networks [PDF]
IACR Cryptology ePrint Archive, 2017 Permissionless blockchains protocols such as Bitcoin are inherently limited in transaction throughput and latency. Current efforts to address this key issue focus on off-chain payment channels that can be combined in a Payment-Channel Network (PCN) to ...

Adding concurrency to smart contracts [PDF]
Distributed computing, 2017 Modern cryptocurrency systems, such as the Ethereum project, permit complex financial transactions through scripts called smart contracts. These smart contracts are executed many, many times, always without real concurrency.

Stackable Transactional File System Using Kernel-Level WAL
IEEE Access, 2022 User applications that require transactional file access generally use user-level transactional protocols such as logging, atomic rename, since the POSIX interface does not support transactional file operations.

Virtual Machine Support for Many-Core Architectures: Decoupling Abstract from Concrete Concurrency Models [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 The upcoming many-core architectures require software developers to exploit concurrency to utilize available computational power. Today's high-level language virtual machines (VMs), which are a cornerstone of software development, do not provide ...

A Scalable Data Structure for Efficient Graph Analytics and In-Place Mutations
Data, 2023 The graph model enables a broad range of analyses; thus, graph processing (GP) is an invaluable tool in data analytics. At the heart of every GP system lies a concurrent graph data structure that stores the graph. Such a data structure needs to be highly
