Opencl max work group size
WebDo not think that a single work group is the same thing as a single compute shader invocation; there's a reason why it is called a "group". Within a single work group, there may be many compute shader invocations. How many is defined by the compute shader itself, not by the call that executes it. This is known as the local size of the work group. Web12 de ago. de 2013 · I'm playing around by changing the local group size when enqueuing the kernel. These are the performance results I get with different sizes when generating …
Opencl max work group size
Did you know?
WebThen if you know that which OCL flag corresponds to your interest (size of GPU memory available for OCL) you could look for that, ie. clinfo grep "Global memory size" . CL_DEVICE_GLOBAL_MEM_SIZE is - as also posted above in the question - 512MB, but this is not what I am searching for, see the explanation in my question.

Webcl_device_max_work_group_size应该返回一个size_t值(例如512,但我不知道它在您的系统上会是什么)。这是工作组中工作项目的最大数量,而不是每个维度中的最大数量。因此,在您的情况下,您尝试创建一个32 * 32 = 1024个工作项的2d工作组,并且cl_device_max_work_group_size可能在系统上小于1024。 WebAddress is outside of memory allocated for variable. One of my students was trying to port some pure C code to OpenCL kernel at a very early stage and encountered a problem with RX580 dGPU while using clbuildprogram. In the meantime, the code has no building problem with RX5700 dGPU and CPU runtimes (pocl3 and intel CPU runtime).

So if I understand everything correctly, then CL_KERNEL_WORK_GROUP_SIZE gives as the ‘ultimate’ number of work-items that can be assigned to 1 work-group. And this we can find out only after we create a kernel. … Web12 de mar. de 2014 · 由于opencl内核运行时,clEnqueueNDRangeKernel的第5、6个参数global大小和local大小影响计算效率,甚至执行成功情况,想深入了解一下相关的几个参数。参考平台上运行clinfo的输出,最终在CL_DEVICE_MAX_WORK_GROUP_SIZES这个参数上难以解释。查了很多资料,多数只是说明并不合理。
