Caffe

Build Status License

Caffe is a deep learning framework made with expression, speed, and modularity in mind. It is developed by the Berkeley Vision and Learning Center (BVLC) and community contributors.

Check out the project site for all the details like

and step-by-step examples.

Join the chat at https://gitter.im/BVLC/caffe

Please join the caffe-users group or gitter chat to ask questions and talk about methods and models. Framework development discussions and thorough bug reports are collected on Issues.

Happy brewing!

Intel® Distribution of Caffe*

This fork is dedicated to improving Caffe performance when running on CPU, in particular Intel® Xeon processors.

Building

Build procedure is the same as on bvlc-caffe-master branch. Both Make and CMake can be used. When OpenMP is available will be used automatically.

Running

Run procedure is the same as on bvlc-caffe-master branch.

Current implementation uses OpenMP threads. By default the number of OpenMP threads is set to the number of CPU cores. Each one thread is bound to a single core to achieve best performance results. It is however possible to use own configuration by providing right one through OpenMP environmental variables like OMP_NUM_THREADS or GOMP_CPU_AFFINITY.

If some system tool like numactl is used to control CPU affinity, by default caffe will prevent to use more than one thread per core. When less than required cores are specified, caffe will limit execution of OpenMP threads to specified cores only.

Best performance solution

Please read our Wiki for our recommendations and configuration to achieve best performance on Intel CPUs.

Multinode Training

Intel® Distribution of Caffe* multi-node allows you to execute deep neural network training on multiple machines.

To understand how it works and read some tutorials, go to our Wiki. Start from Multinode guide.
