OptSmart: A Space Efficient Optimistic Concurrent Execution of Smart Contracts
Parwat Singh Anjana, Sweta Kumari, Sathya Peri +2
Popular blockchains such as Ethereum and several others execute complex transactions in blocks through user-defined scripts known as smart contracts. Serial execution of smart cont…
Optimal Resilience in Systems that Mix Shared Memory and Message Passing
Hagit Attiya, Sweta Kumari, Noa Schiller
We investigate the minimal number of failures that can partition a system where processes communicate both through shared memory and by message passing. We prove that this number p…
Nucleation of twinning dislocation loops in fcc metals
Sweta Kumari, Amlan Dutta
Deformation twinning, which occurs in fcc metals only under particular conditions of intrinsic material properties, microstructure, and loading conditions, occupies an indispensabl…
Store-Collect in the Presence of Continuous Churn with Application to Snapshots and Lattice Agreement
Hagit Attiya, Sweta Kumari, Archit Somani +1
We present an algorithm for implementing a store-collect object in an asynchronous crash-prone message-passing dynamic system, where nodes continually enter and leave. The algorith…
An Efficient Approach to Achieve Compositionality using Optimized Multi-Version Object Based Transactional Systems
Chirag Juyal, Sandeep Kulkarni, Sweta Kumari +2
In the modern era of multi-core systems, the main aim is to utilize the cores properly. This utilization can be done by concurrent programming. But developing a flawless and well-o…
Achieving Starvation-Freedom with Greater Concurrency in Multi-Version Object-based Transactional Memory Systems
Chirag Juyal, Sandeep Kulkarni, Sweta Kumari +2
To utilize the multi-core processors properly concurrent programming is needed. Concurrency control is the main challenge while designing a correct and efficient concurrent program…
Efficient Concurrent Execution of Smart Contracts in Blockchains using Object-based Transactional Memory
Parwat Singh Anjana, Hagit Attiya, Sweta Kumari +2
This paper proposes an efficient framework to execute Smart Contract Transactions (SCTs) concurrently based on object semantics, using optimistic Single-Version Object-based Softwa…
An Efficient Framework for Optimistic Concurrent Execution of Smart Contracts
Parwat Singh Anjana, Sweta Kumari, Sathya Peri +2
Blockchain platforms such as Ethereum and several others execute complex transactions in blocks through user-defined scripts known as smart contracts. To append a correct block int…
An Innovative Approach to Achieve Compositionality Efficiently using Multi-Version Object Based Transactional Systems
Chirag Juyal, Sandeep Kulkarni, Sweta Kumari +2
In the modern era of multicore processors, utilizing cores is a tedious job. Synchronization and communication among processors involve high cost. Software transaction memory syste…
Achieving Starvation-Freedom in Multi-Version Transactional Memory Systems
Ved Prakash Chaudhary, Chirag Juyal, Sandeep Kulkarni +2
Software Transactional Memory systems (STMs) have garnered significant interest as an elegant alternative for addressing synchronization and concurrency issues with multi-threaded…
