Opencl workgroup
Web29 de jul. de 2024 · OpenCL执行模型（Execution Model)解释了opencl程序是如何运行的，是理解opencl的基础。OpenCL程序Opencl应用程序一般分为host部分和kernel部分组成，它与平台模型紧密联系。Host部分的代码主要是运行在host，主要作用是对Opencl进行初始化，创建context以及命令通道，提交命令，copy数据到device上等功能。 WebIt's basically a kind of abstraction of the hardware. While subgroups act in lockstep, the whole threadgroup shared local memory cache. Multiple threadgroups can run on a single compute unit, which has a single bank of cache. Choosing a threadgroup size is primarily a task of optimizing usage of a compute unit.

Web22 de nov. de 2014 · A workgroup size can be limited because the local memory is limited. And this limit can be reached if you have a kernel that uses lots of private memory (“lots” is a relative term – on weaker hardware this may be reached even with seemingly few variables). "However this limit is just under ideal conditions. If your kernel uses high amount ...
