Stride memory access
WebDec 4, 2013 · In this code, I am using grid-stride loops, described in an earlier CUDA Pro Tip post. Figure 1 shows the throughput of the kernel in GB/s as a function of copy size. Figure 1: Copy bandwidth as a function of copy size. We can inspect the assembly for this kernel using the cuobjdump tool included with the CUDA Toolkit. %> cuobjdump -sass executable WebApr 11, 2024 · The input size is down-sampled from 128 × 128 × 2 to 16 × 16 × 1 after three layers of convolution with a stride of 2 and two layers with a stride of 1. Finally, the results are obtained through the Sigmoid layer. All convolution uses a 3 × 3 convolution kernel, and LeakyReLU is used as the activation function.

WebStride Prefetcher • Like a stream prefetcher, but with variable access stride (not always +1) – More bookkeeping to determine stride • Also requires confirmation before prefetching – Allocate stream on access A – Determine direction and stride on access A+X – Confirm stream on access A+2*X – Begin prefetching A+3*X WebThe memory access pattern is called strided when memory fields accessed are equally distant. This distance is called a stride (not to be mistaken with SIMD-stride!). A simple visualization of strided access: As you can see, the STRIDE-1 access is a special case of GATHER operation: a LOAD operation.
