Linear equations with large spare coefficient matrices arise in many practical scientific and engineering problems. Previous sparse matrix algorithms for solving linear equations based on single-core CPU are highly complex and time-consuming. To solve such problems, aiming at Jacobi iteration algorithm, in this paper we firstly implement a sparse matrix parallel iteration algorithm on a hybrid multi-core...
Currently GPU is used as a coprocessor to accelerate computation in heterogeneous concurrency systems comprised of CPU and GPU. However, the architecture of main core plus coprocessor needs extra spending on communication. An effective method to solve this problem is to process data in batches in order to overlap communication and computation. But without a specific partitioning method, users always...
CUDA facilitates the development of General Purpose computing on Graphics Processing Units (GPGPU), however, its complex memory system, thread-level structure, and data transmission control between memories have brought great challenges for programming on GPU. In order to facilitate the development of parallel programs on GPU and reuse existing sequential codes, in this paper we propose a novel directive...
