Opencl reduction operation performance
WebOpenCL. OpenCL™ (Open Computing Language) is a low-level API for heterogeneous computing that runs on CUDA-powered GPUs. Using the OpenCL API, developers can launch compute kernels written using a limited subset of the C programming language on a GPU. NVIDIA is now OpenCL 3.0 conformant and is available on R465 and later drivers. Web26 de abr. de 2024 · All reduction performance experiments are performed on a ZYNQ 7010. The hardware kernels are generated using VIV ADO HLS 2016.3 and synthesized using VIV ADO 2016.3.

Web19 de out. de 2024 · 5.1 OpenCL performance on GPU compared the CPU one. OpenCL offers a convenient way to construct heterogeneous computing systems and opportunities to improve parallel application performance. As first step, the OpenCL SAD kernel was implemented in two platforms: CPU with 4 cores at frequency 2.5 GHz and an NVDIA … Weboperations are required. Finally, each OpenCL kernel launch requires the speci cation of local and global work sizes. We restrict the choice of local work sizes to powers of two up to a value of 512, because other workgroup sizes are either not well-suited for parallel reduction operations such as inner products, or exhaust the available local ...
