WebMemory Size Limitations Private – if too many registers are used per thread, will start to spill into thread-visible main memory Global – limited by the amount of main memory of device Constant – device limited, usually 64KB per device Local – device limited, usually 32KB per compute-unit Movement between memory spaces Web如前所述,在fft算法中,fft大小等于输入块的大小,滤波器被填充到与输入块相同的大小。论文只在单个卷积层中计算两种大小(n = 4和n = 8)的fft。因为当fft大小大于8时,片上内存不足以存储论文框架中的所有缓冲区。平均而言,论文的性能模型的预测误差为10.1%。

WebLocal memory can be used to avoid multiple redundant reads from and writes to global memory. But it is important to note that the SLM (which is used to implement local … Web3 de nov. de 2009 · Since we cannot use memcpy in OpenCL, i am wondering if there is a similar function available that can be used to copy chunks of data from __global to __private (or to __local) inside a kernel. For example say I wish to copy 10 elements from global memory to __private memory (per thread). I do not wish to make a loop like: option childoption
