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 … Web1 de dez. de 2024 · For example, “bbmat” and “FEM_3D_thermal” in ELL and “TSOPF_RS_b2383” in both CSR and ELL. Moreover, the SpMV based on CSR and … WebSparse matrix-vector multiplication (SpMV) is a fundamental building block for numerous applications. In this paper, we propose CSR5 (Compressed Sparse Row 5), a new storage format, which offers high-throughput SpMV on various platforms including CPUs, GPUs and Xeon Phi.
