Parallel Fourier Space Image Similarity Calculation Based on SIMD [PDF]
Jisuanji gongcheng, 2021 The existing models for calculation of three-dimensional cryo-Electron Microscope(cryo-EM) reconstruction frequently call the Fourier space-based image similarity algorithm,and the generated high computational overhead slows the running speed of the ...

Concurrency and Computation: Practice and Experience, Volume 35, Issue 28, 25 December 2023., 2023 Summary In this article, we explore the usage of scalable vector extension (SVE) to vectorize number‐theoretic transforms (NTTs). In particular, we show that 64‐bit modular arithmetic operations, including modular multiplication, can be efficiently implemented with SVE instructions.

Fine‐grain task‐parallel algorithms for matrix factorizations and inversion on many‐threaded CPUs
Concurrency and Computation: Practice and Experience, Volume 35, Issue 27, 10 December 2023., 2023 Abstract We extend a two‐level task partitioning previously applied to the inversion of dense matrices via Gauss–Jordan elimination to the more challenging QR factorization as well as the initial orthogonal reduction to band form found in the singular value decomposition.

Wirelessly interfacing sensor‐equipped implants and MR scanners for improved safety and imaging
Magnetic Resonance in Medicine, Volume 90, Issue 6, Page 2608-2626, December 2023., 2023 Abstract Purpose To investigate a novel reduced RF heating method for imaging in the presence of active implanted medical devices (AIMDs) which employs a sensor‐equipped implant that provides wireless feedback. Methods The implant, consisting of a generator case and a lead, measures RF‐induced E$$ E $$‐fields at the implant tip using a simple sensor in

A portable C++ library for memory and compute abstraction on multi‐core CPUs and GPUs
Concurrency and Computation: Practice and Experience, Volume 35, Issue 25, 15 November 2023., 2023 Abstract We present a C++ library for transparent memory and compute abstraction across CPU and GPU architectures. Our library combines generic data structures like vectors, multi‐dimensional arrays, maps, graphs, and sparse grids with basic generic algorithms like arbitrary‐dimensional convolutions, copying, merging, sorting, prefix sum, reductions ...
