  1. # Release 0.1.0-alpha
  2. This is the initial release of GraphEngine(GE) which was designed by the researchers and engineers in Huawei Technologies Co.,Ltd. GE is implemented via C++ and acts as a powerful backing force for MindSpore. GE is a linked up module between MindSpore front end and Ascend Chips.
  3. ## Main features
  4. - GE API
  5. - GE provides an unified interface with the front end including graph management interfaces i.e., graph loading and graph execution, and GE core initiallization and finalization interfaces.
  6. - Graph Processing
  7. - Six parts of graph processing operations are executed within GE, i.e. graph preparation, graph partition, graph optimization, graph compilation, graph loading and graph execution.
  8. - GE highly optimizes the graph defined by the front end to a form which can be effectively executed on Ascend Chips.
  9. - GE supports several optimizations to reduce computation costs, e.g. operator fusion, parallel operation, data format transition.
  10. - Debugging
  11. - GE supports data dump and graph dump for debugging.
  12. - GE provides profiling tools to thoroughly analyze the speed performances.

图引擎模块(GE)是MindSpore的一个子模块,其代码由C++实现,位于前端模块ME和底层硬件之间,起到承接作用。图引擎模块以ME下发的图作为输入,然后进行一系列的深度图优化操作,最后输出一张可以在底层硬件上高效运行的图。GE针对昇腾AI处理器的硬件结构特点,做了特定的优化工作,以此来充分发挥出昇腾AI处理器的强大算力。在进行模型训练/推理时,GE会被自动调用而用户并不感知。GE主要由GE API和GE Core两部分组成,详细的架构图如下所示
