Discovering Approximate and Significant High-Utility Patterns from Transactional Datasets

open access: yesJournal of Mathematics, 2022
Mining high-utility pattern (HUP) on transactional datasets has been widely discussed, and various algorithms have been introduced to settle this problem. However, the time-space efficiency of the algorithms is still limited, and the mining system cannot

Scalable Distributed Metadata Server Based on Nonblocking Transactions [PDF]

open access: yesJournal of Universal Computer Science, 2020
Metadata performance scalability is critically important in high-performance computing when accessing many small files from millions of clients. This paper proposes a design of a scalable distributed metadata server, PPMDS, for parallel file systems ...

Parallel Algorithm for Frequent Itemset Mining on Intel Many-core Systems [PDF]

open access: yes, 2018
Frequent itemset mining leads to the discovery of associations and correlations among items in large transactional databases. Apriori is a classical frequent itemset mining algorithm, which employs iterative passes over database combining with generation

A simulation of distributed STM [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2018
This paper presents an extension of the IaaS Cloud simulator CloudSim. Computational tasks are modeled in the form of a transaction on a transactional memory and communication between the data center is based on the Two-Phase Commit protocol ...

Some Challenges of Specifying Concurrent Program Components [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
The purpose of this paper is to address some of the challenges of formally specifying components of shared-memory concurrent programs. The focus is to provide an abstract specification of a component that is suitable for use both by clients of the ...

OneFile: A Wait-Free Persistent Transactional Memory

open access: yesDependable Systems and Networks, 2019
A persistent transactional memory (PTM) library provides an easy-to-use interface to programmers for using byte-addressable non-volatile memory (NVM). Previously proposed PTMs have, so far, been blocking.

Intent Arabic text categorisation based on different machine learning and term frequency

open access: yesIET Networks, EarlyView., 2022
Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...

Prompt Application-Transparent Transaction Revalidation in Software Transactional Memory [PDF]

open access: yes, 2017
Software Transactional Memory (STM) allows encapsulating shared-data accesses within transactions, executed with atomicity and isolation guarantees. The assessment of the consistency of a running transaction is performed by the STM layer at specific ...

ParaTM: Transparent Embedding of Hardware Transactional Memory for Traditional Applications

open access: yesIEEE Access, 2018
As the many-core processors become more prevalent, the parallelism degree of applications is rapidly increasing. It is well known that multi-thread approaches are an effective solution to improve performance by exploiting multiple cores.

Locality-Adaptive Parallel Hash Joins Using Hardware Transactional Memory [PDF]

open access: yes, 2016
Previous work [1] has claimed that the best performing implementation of in-memory hash joins is based on (radix-)partitioning of the build-side input.
