Hi, Thank you for the nice work! But I encountered an issue; I cannot run the example.

When I run the example with:

build/tools/caffe.bin test -model models/bvlc_reference_caffenet/test_direct_sconv_mkl.prototxt -weights models/bvlc_reference_caffenet/logs/acc_57.5_0.001_5e-5_ft_0.001_5e-5/0.001_5e-05_0_1_0_0_0_0_Sun_Jan__8_07-35-54_PST_2017/caffenet_train_iter_640000.caffemodel

I got this error:

My environment is as follow: OS: Ubintu 14.04 CPU: Intel Xeon E5-2630 (12 cores) icc version: 18.0.5 boost version : 1.59.0

I modified Makefile.config in order to refer to boost path:

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include src src/libxsmm/include $(CUDA_DIR)/include /home/alspace/Kit/boost/include LIBRARY_DIRS := $(PYTHON_LIB) /usr/lib src/SpMP src/libxsmm/lib $(CUDA_DIR)/lib64 /home/alspace/Kit/boost/lib

I have no error for 'make all' and 'make test', but 'make runtest' shows following error: (Note: building the original caffe does not show any error)

Oh, it was due to AVX2. My cpu does not support AVX2 but only AVX.

I build libxsmm with AVX and now it works! Thanks.
