CXXNET安装

环境：ubuntu 14.04,  cuda 6.5

先安装cuda-toolkit, cuda-cublas, cudart, cuda-curand这四个安装包

cuda_6.5.14_linux_64.run

cuda-cublas-6-5_6.5-14_amd64.deb
cuda-cudart-6-5_6.5-14_amd64.deb
cuda-curand-6-5_6.5-14_amd64.deb

下载路径：http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/

安装 OpenCV

sudo apt-get install libopencv-2.4

 

配置环境变量

vi ~/.bashrc

export CUDA_HOME=/usr/local/cuda-6.5
export PATH=$CUDA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib64:/usr/local/lib:$LD_LIBRARY_PATH
export CPLUS_INCLUDE_PATH=/usr/local/cuda/include

 

下载一份cxxnet

git clone https://github.com/dmlc/cxxnet.git

切换至目录 cd cxxnet

拷贝一份配置到当前目录 cp make/config.mk .

修改 vi config.mk

USE_CUDA = 1

USE_BLAS = blas

USE_DIST_PS = 1
USE_OPENMP_ITER = 1

编辑 vi  Makefile， 修改如下：

CFLAGS += -g -O3 -I./mshadow/  -fPIC $(MSHADOW_CFLAGS) -fopenmp -I/usr/local/cuda/include
LDFLAGS = -pthread $(MSHADOW_LDFLAGS) -L/usr/local/cuda/lib64

 

最后编译文件

./build.sh
