Anakin2.0

Welcome to the Anakin GitHub.

Anakin is a cross-platform, high-performance inference engine, which is originally developed by Baidu engineers and is a large-scale application of industrial products.

Please refer to our release announcement to track the latest feature of Anakin.

Features

• Flexibility

  Anakin is a cross-platform, high-performance inference engine, supports a wide range of neural network architectures and different hardware platforms. It is easy to run Anakin on GPU / x86 / ARM platform.

  Anakin has integrated with NVIDIA TensorRT and open source this part of integrated API to provide services, developers can call the API directly or modify it as needed, which will be more flexible for development requirements.

• High performance

  In order to give full play to the performance of hardware, we optimized the forward prediction at different levels.

  • Automatic graph fusion. The goal of all performance optimizations under a given algorithm is to make the ALU as busy as possible. Operator fusion can effectively reduce memory access and keep the ALU busy.

  • Memory reuse. Forward prediction is a one-way calculation. We reuse the memory between the input and output of different operators, thus reducing the overall memory overhead.

  • Assembly level optimization. Saber is a underlying DNN library for Anakin, which is deeply optimized at assembly level.

NV GPU Benchmark

Machine And Enviornment

CPU: Intel(R) Xeon(R) CPU 5117 @ 2.0GHz
GPU: Tesla P4
cuda: CUDA8
cuDNN: v7

• Time：warmup 10，running 1000 times to get average time
• Latency (ms) and Memory(MB) of different batch

The counterpart of Anakin is the acknowledged high performance inference engine NVIDIA TensorRT 5 , The models which TensorRT 5 doesn't support we use the custom plugins to support.
