With the advent of multi-core systems, GPUs and FPGAs, loop parallelization has become a promising way to speedup program execution. In order to stay up with time, various performance-oriented programming languages provide a multitude of constructs to allow programmers to write parallelizable loops. Correspondingly…

- Evaluating how well a whole system or set of subsystems performs is one of the primary objectives of performance testing. We can tell via performance assessment if the architecture implementation meets the design objectives. Performance evaluations of several parallel algorithms are compared in this study. Both…

'Tao Tang' 'Yingbo Cui'] Background The advent of Single Molecule Real-Time (SMRT) sequencing has overcome many limitations of second-generation sequencing, such as limited read lengths, PCR amplification biases. However, longer reads increase data volume exponentially and high error rates make many existing alignment…

'Robert Höldrich' 'Michael Iber' 'Alexander Bock' 'Anders Ynnerman' 'Wolfgang Aigner' 'Niklas Rönnberg'] One of the commonly used visualization techniques for multivariate data is the parallel coordinates plot. It provides users with a visual overview of multivariate data and the possibility to interactively explore…

—One of the key objectives in many fields in machine learning is to discover causal relationships among a set of variables from observational data. In linear non-Gaussian acyclic models (LiNGAM), it can be shown that the true underlying causal structure can be identified uniquely from merely observational data.…

Parallel computing is a current algorithmic approach to looking for efficient solutions; that is, to define a set of processes in charge of performing at the same time the same task. Advances in hardware permit the massification of accessibility to and applications of parallel computing. Nonetheless, some algorithms…

Durbin’s positional Burrows-Wheeler transform (PBWT) enables algorithms with the optimal time complexity of $OMN$ for reporting all vs all haplotype matches in a population panel with $M$ haplotypes and $N$ variant sites. However, even this efficiency may still be too slow when the number of haplotypes reaches…

Farrar recommends employing a stripe method to enhance the implementation of in-sequence parallelism, resulting in significant improvements in parallel performance through the utilization of the SIMD instruction set. This method involves reorganizing the originally sequential computation. The length of each stripe…

computer system based on Amdahl's law Authors: ['Aleksandr S. Filipchenko'] Abstract The modification of Amdahl's law for the case of increment of processor elements in a computer system is considered. The coefficient k linking accelerations of parallel and parallel specialized computer systems is determined. The…
