A parallel system to solve complex computational problems involve multiple instruction, simultaneous flows, communication structures, synchronisation and competition conditions between processes, as well as mapping and balance of workload in each processing unit. the algorithm design and the facilities of processing units will affect the cost-performance ratio of any algorithm. We propose a generic methodology to capture the main characteristics of parallel algorithm design methodologies, and to add the experience of expert programmers through pattern languages. Robust design considering the relations between architectures and programs is a crucial item to implement high-quality parallel algorithms. We aim for a methodology to exploit algorithmic concurrencies and to establish optimal process allocation into processing units, exploring the lowest implementation details. Some basic examples are described, such as the k-means algorithm, to illustrate and to show the effectiveness of our methodology. Our proposal identifies essential design patterns to find models of Data Mining algorithms with string self-adaptive mechanisms for homogeneous and heterogeneous parallel architectures. © Springer Nature Switzerland AG 2019.

the discrete wavelet transform can be found at the heart of many image-processing algorithms. Until now, the transform on general-purpose processors (CPUs) was mostly computed using a separable lifting scheme. As the lifting scheme consists of a small number of operations, it is preferred for processing using single-core CPUs. However, considering a parallel processing using multi-core processors, this scheme is inappropriate due to a large number of steps. On such architectures, the number of steps corresponds to the number of points that represent the exchange of data. Consequently, these points often form a performance bottleneck. Our approach appropriately rearranges calculations inside the transform, and thereby reduces the number of steps. In other words, we propose a new scheme that is friendly to parallel environments. When evaluating on multi-core CPUs, we consistently overcome the original lifting scheme. the evaluation was performed on 61-core Intel Xeon Phi and 8-core Intel Xeon processors.

the complexity of efficiently programming massively parallel machines is illustrated by presenting a number of algorithms. these algorithms deal with computational geometry, data histogramming, list manipulation, and other problems or operations that arise in computer vision tasks. All of the algorithms presented use a divide-and-conquer strategy, and they all use routines that solve a problem of size M using a machine size N, where M >

Multi-access edge computing (MEC) technology is a potential solution to the conflict between resource-constrained unmanned aerial vehicles (UAVs) and various emerging computationally intensive, delay-sensitive applications of UAVs. In this paper, we study the joint optimization problem of distributed computation offloading and resource allocation in MEC-supported UAV application scenarios, where the task of each UAV can be divided and offloaded to multiple servers deployed in ground wireless access points (WAPs) for parallel processing. To enhance the quality of user experience (QoE) while avoiding excessive optimization, we propose a new user satisfaction function to evaluate the task processing level of MEC network, which respectively scores the actual task processing delay and energy consumption based on different criteria determined by task requirements. We aim to trade off delay and energy consumption by jointly optimizing server selection, computing resource allocation, transmission power control, and task allocation to achieve maximum user satisfaction. the joint optimization problem is formulated as a mixed-integer nonlinear programming (MINLP) problem. To reduce the complexity of the joint optimization problem, it is decomposed into three sub-problems based on the divide-and-conquer approach: server computing resource allocation, transmission power control, and task offloading decision. We propose a three-layer intelligent optimization (TIO) algorithm, which employs the Lagrange multiplier method, the AdaDelta gradient descent method, and our proposed multivariate decoupling-particle swarm optimization (MD-PSO) algorithm to solve the above three sub-problems alternately for gradually approaching the maximum user satisfaction. the numerical results show that our proposed algorithm is significantly superior to the benchmark algorithms in terms of solving speed, accuracy, and stability. © 2023 IEEE.

the hardness of solving multivariate quadratic (MQ) systems is the underlying problem for multivariate-based schemes in the field of post-quantum cryptography. the concrete, practical hardness of this problem needs to be measured by state-of-the-art algorithms and high-performance implementations. We describe, implement, and evaluate an adaption of the Crossbred algorithm by Joux and Vitse from 2017 for solving MQ systems over F-2. Our adapted algorithm is highly parallelizable and is suitable for solving MQ systems on GPU architectures. Our implementation is able to solve an MQ system of 134 equations in 67 variables in 98.39 hours using one single commercial Nvidia GTX 980 graphics card, while the original Joux-Vitse algorithm requires 6200 CPU-hours for the same problem size. We used our implementation to solve all the Fukuoka Type-I MQ challenges for n is an element of{55,..., 74}. Based on our implementation, we estimate that the expected computation time for solving an MQ system of 80 equations in 84 variables is about one year using a cluster of 3600 GTX 980 graphics cards. these parameters have been proposed for 80-bit security by, e.g., Sakumoto, Shirai, and Hiwatari at Crypto 2011.

Scalable parallel computational geometry for coarse grained multicomputers

引用

international JOURNAL OF COMPUTATIONAL GEOMETRY & APPLICATIONS 1996年第3期6卷 379-400页

We study scalable parallel computational geometry algorithms for the coarse grained multicomputer model: p processors solving a problem on n data items, were each processor has O(n/p) much greater than O(1) local memory and all processors are connected via some arbitrary interconnection network (e.g. mesh, hypercube, fat tree). We present O(T-sequential/p + T-s(n,p)) time scalable parallel algorithms for several computational geometry problems. T-s(n,p) refers to the time of a global sort operation. Our results are independent of the multicomputer's interconnection network. their time complexities become optimal when T-sequential/p dominates T-s(n,p) or when T-s(n,p) is optimal. this is the case for several standard architectures, including meshes and hypercubes, and a wide range of ratios n/p that include many of the currently available machine configurations. Our methods also have some important practical advantages: For interprocessor communication, they use only a small fixed number of one global routing operation, global sort, and all other programming is in the sequential domain. Furthermore, our algorithms use only a small number of very large messages, which greatly reduces the overhead for the communication protocol between processors. (Note however, that our time complexities account for the lengths of messages.) Experiments show that our methods are easy to implement and give good timing results.
