Message progression in parallel computing - to thread or not to thread? [PDF]
2008 IEEE International Conference on Cluster Computing, 2008 Message progression schemes that enable communication and computation to be overlapped have the potential to improve the performance of parallel applications. With currently available high-performance networks there are several options for making progress: manual progression, use of a progress thread, and communication offload. In this paper we analyze

Thread-safe lattice Boltzmann for high-performance computing on GPUs [PDF]
Journal of Computational Science, 2023 We present thread-safe, highly-optimized lattice Boltzmann implementations, specifically aimed at exploiting the high memory bandwidth of GPU-based architectures. At variance with standard approaches to LB coding, the proposed strategy, based on the reconstruction of the post-collision distribution via Hermite projection, enforces data locality and ...

A Review of Lightweight Thread Approaches for High Performance Computing [PDF]
2016 IEEE International Conference on Cluster Computing (CLUSTER), 2016 High-level, directive-based solutions are becoming the programming models (PMs) of the multi/many-core architectures. Several solutions relying on operating system (OS) threads perfectly work with a moderate number of cores. However, exascale systems will spawn hundreds of thousands of threads in order to exploit their massive parallel architectures ...

Detection of Screw Threads in Computed Tomography 3D Density Fields [PDF]
Measurement Science Review, 2013 Abstract Measurements and inspection in production must be rapid, robust and automated. In this paper a new method is proposed to automatically detect screw threads in 3D density fields obtained from computed tomography measurement devices. The described method can be used to automate many operations during screw thread inspection process and ...

Computing Method of Bolted Joint Critical Loosening Load with Flexible Thread [PDF]
Journal of Mechanical Engineering, 2020 ： Bolted joint loosening is one of the important modes of bolted joint failure. In the project, the bolted joints are often subjected to alternating lateral dynamic loads, and the bolts tend to loosening very easily as the bolt axis is perpendicular to ...

A Micro Threading Based Concurrency Model for Parallel Computing [PDF]
2011 IEEE International Symposium on Parallel and Distributed Processing Workshops and Phd Forum, 2011 The continuing launch of various multi-core processors popularizes parallel computing of gaining higher performance, however, it also exerts pressures on software developers concerning how to make full use of the multiplicity of resources to get the required benefits due to high coupling of parallel programs to specified hardware.

Analysis of Threading Libraries for High Performance Computing [PDF]
IEEE Transactions on Computers, 2020 With the appearance of multi-many core machines, applications and runtime systems evolved in order to exploit the new on-node concurrency that brought new software paradigms. POSIX threads (Pthreads) was widely-adopted for that purpose and it remains as the most used threading solution in current hardware.
