Quote: The Skylake microarchitecture implements a different state machine than prior generations to manage the YMM state transition associated with mixing SSE and AVX instructions. It no longer saves the entire upper YMM state when executing an SSE instruction when in “Modified and Unsaved” state, but saves the upper bits of individual register. As a result, mixing SSE and AVX instructions will experience a penalty associated with partial register dependency of the destination registers being used and additional blend operation on the upper bits of the destination registers. Such type of penalties have a huge impact on openvino's and oneDNN's kernels. Basically the mixing of VEX and non-VEX instructions should be avoided.
OpenVINO™ Toolkit
This toolkit allows developers to deploy pre-trained deep learning models through a high-level C++ Inference Engine API integrated with application logic.
This open source version includes several components: namely Model Optimizer, nGraph and Inference Engine, as well as CPU, GPU, MYRIAD, multi device and heterogeneous plugins to accelerate deep learning inferencing on Intel® CPUs and Intel® Processor Graphics. It supports pre-trained models from the Open Model Zoo, along with 100+ open source and public models in popular formats such as Caffe*, TensorFlow*, MXNet* and ONNX*.
