I wish to implement an operation similar to 2D convolution in TensorFlow. As per my understanding, the most common approach to implementing convolution is by first applying an im2col operation to the image (see here - subsection "Implementation as Matrix Multiplication") - an operation that transforms an image into a 2D matrix with individual "chunks" of the image to which the kernel is ... Witryna2. img2col. img2col是把卷积操作转换为通用矩阵乘法（GEneral Matrix Multiply，GEMM）的方法，使用矩阵乘法表示卷积操作后，我们就可以专注于优化矩阵乘法，而不是再分散资源与精力对卷积进行优化，达到针对性地优化的效果。. 要理解img2col，我们先从简单的情况开始 ...

Witryna30 sty 2024 · This means that when comparing two GPUs with Tensor Cores, one of the single best indicators for each GPU’s performance is their memory bandwidth. For example, The A100 GPU has 1,555 GB/s memory bandwidth vs the 900 GB/s of the V100. As such, a basic estimate of speedup of an A100 vs V100 is 1555/900 = 1.73x.
