Opencl을 이용한 고속 csr spmv
Webbly level on three exemplar OpenCL benchmarks: SGEMM, SpMV, and FFT. We also identify a number of tuning knobs that are critical to per-formance portability, including threads-data mapping, data layout, tiling size, data caching, and operation-speci c factors. We further demonstrate that proper tuning could improve the OpenCL portable … http://parlab.eecs.berkeley.edu/sites/all/parlab/files/clspMV-%20Keutzer.pdf

WebSWCSR-SpMV to a PESTc based application which simulates the earth magnetic field, and the result shows that this application can be accelerated by 1.75x to 2.69x when invoking SWCSR-SpMV in a multi-process environment on the Sunway TaihuLight supercom-puter. This paper is organized as follows: In Section 2 we will highlight WebOpenCL [16]. The goal of OpenCL is to make parallel code portable to heterogeneous platforms. With OpenCL, we can expect to develop an autotuner that can tune the SpMV …
Web17 de dez. de 2015 · Sparse matrix vector multiplication (SpMV) is a basic building block of many scientific applications. Several GPU accelerated SpMV algorithms for the CSR … WebCompressed sparse row (CSR) is a frequently used format for sparse matrix storage. However, the state-of-the-art CSR-based sparse matrix-vector multiplication (SpMV) implementations on CUDA-enabled GPUs do not exhibit very high efficiency. This has motivated the development of some alternative storage formats for GPU computing. …
Web9 de dez. de 2024 · CSR (Compressed Sparse Row) is the most popular and widely used sparse matrix representation format for Sparse Matrix-Vector Multiplication (SpMV), which is a key operation in many scientific and engineering applications. However, considering different matrix features and the given GPUs, CSR-based SpMV on some sparse … Web1 de jan. de 2015 · The widely used Compressed Sparse Row (CSR) sparse matrix storage format was chosen to carry on this study for sustainability and reusability reasons. We parallelized for Intel Many Integrated Core (MIC) architecture a vectorized SpMV kernel using MPI and OpenMP, both pure and hybrid versions of them.
