Implementing a convolutional neural network using MKL

jean-vezina — Fri, 24 Mar 2017 00:24:58 GMT

Good evening,

After discovering that it is not possible to build MKL-DNN on Windows, I would like to know if there is an example code or some hints about implementing a convolutional neural network (CNN) using the primitives already implemented in the MKL library available with XE 2017 release 2?

Thanks in advance,

Jean Vezina

mkl-dnn-0.7 version is

mkl-dnn-0.7 version is available from github. You may have a look at the source code and see the implementations details (e.x - ..\intel-Caffe\mkl-dnn-0.7\src\cpu\jit_avx2_1x1_conv_kernel_f32.cpp - you will show the AVX2 specific implementation )

Thanks a lot!

Thanks,

I will check the convolution functions of IPP.

FYI, I have also noticed that some other deep learning tools that call MKL such as the Intel versions of Caffe and Neon cannot also be compiled on Windows as CMAKE for Windows returns errors and Intel C++ finds errors in the source code when we try to compile manually. Apparently, one has to use GNU C++ (g++) to compile without errors but this is not acceptable in my case as the compiled code cannot be called by Intel Fortran or C++.
