本文简要介绍通用矩阵乘(GEMM,General Matrix Multiplication)优化的基本概念和方法、QNNPACK对特定场景的矩阵乘的优化方法、以及用 GEMM 优化神经网络中卷积计算的一点方向。 旨在帮助大家在概念中建立一些直觉,无甚高论。 通用矩阵乘优化 基本概念 通用矩阵乘(下文简称 GEMM)的一般形式是 = C=AB, 其中 A 和 B ...
③ generates a large database of matrix multiplication algorithms — up to thousands of algorithms for each size (the space is richer than previously known). 有学者指出,这个结果本身提升不大,文中仅对比强调了Strassen's algorithm,但目前理论上最快的算法达到 \text{O}(n^{2.373})(Ryan Williams在Tw...

For multithread option I've created method strassenMultiplication( ) in class matrix. It devides given matrices into sub-matrices and each thread works with its own sub-matrix. Important conditions: Matrices should be square with even dimensions (For example: 2x2, 4x4, 6x6...) Matrices should...
Multiplication without tilingIn this section, consider the multiplication of two matrices, A and B, which are defined as follows:A is a 3-by-2 matrix and B is a 2-by-3 matrix. The product of multiplying A by B is the following 3-by-3 matrix. The product is calculated by multiplying...
native COSMA layout:to get the maximum performance, the native COSMA matrix layout should be used. To get an idea of the performance you can expect to get, please have a look at thematrix multiplication miniapp. The documentation for the latter option will soon be published here. ...
