To begin using nGraph with popular frameworks to accelerate deep learning workloads on deep learning hardware, please refer to the links below.
Frameworks using nGraph Compiler stack to execute workloads have shown a performance boost when compared to native framework implementations. We've also seen performance boosts running workloads that are not included on the list of Validated workloads, thanks to our powerful subgraph pattern matching.
Additionally we have integrated nGraph with PlaidML to provide deep learning performance acceleration on Intel, Nvidia, & AMD GPUs. More details on current architecture of the nGraph Compiler stack can be found in Architecture and Features, and recent changes to the stack are explained in Release Notes.
What is nGraph Compiler?
nGraph Compiler aims to accelerate developing AI workloads using any deep learning framework and deploying to a variety of hardware targets. We strongly believe in providing freedom, performance, and ease-of-use to AI developers.
The diagram below shows deep learning frameworks and hardware targets supported by nGraph. NNP-T and NNP-I in the diagram refer to Intel's next generation deep learning accelerators: Intel® Nervana™ Neural Network Processor for Learning and Inference respectively. Future plans for supporting additional deep learning frameworks and backends are outlined in the ecosystem section.
While the ecosystem shown above is all functioning, we have validated performance for deep learning inference on CPU processors, such as Intel® Xeon® for the Beta release of nGraph.
Our documentation has extensive information about how to use nGraph Compiler stack to create an nGraph computational graph, integrate custom frameworks, and to interact with supported backends.
