|
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. |
|
|
|
## Major Features and Improvements |
|
|
|
- Provides a common graph-level option, and multiple requirements can also share this mechanism in the future. |
|
|
|
- Improve graph compilation performance. |
|
|
|
- Optimize memory allocation. |
|
|
|
- Optimize serveral operators e.g., Slice, StridedSlice, ScatterMax etc. |
|
|

|
|
## Bugfixes |
|
|
|
- Delete redudant codes.([#I1EU2Z](https://gitee.com/mindspore/graphengine/issues/I1EU2Z)) |
|
|
|
- Fix HCCL initilization bugs under train and eval scenarios.([#I1DIBJ](https://gitee.com/mindspore/graphengine/issues/I1DIBJ)) |
|
|
|
- Optimize compilation and linking process, enhancing efficiency and performance of concurrent compilation of GraphEngine and MindSpore. ([#I1DFIY](https://gitee.com/mindspore/mindspore/issues/I1DFIY)) |
|
|
|
- Fix the bug that GE checkpoint cannot save variable names correctly.([#I1DIBJ](https://gitee.com/mindspore/graphengine/issues/I1DIBJ)) |
|
|
|
- Save dump files on every iteration instead of every execution.([#I1DIBJ](https://gitee.com/mindspore/graphengine/issues/I1DIBJ)) |
|
|
|
|
|
|
|
- GE API |
|
|
|
- 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. |
|
|
|
|
|
|
|
- Graph Processing |
|
|
|
- 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. |
|
|
|
- GE highly optimizes the graph defined by the front end to a form which can be effectively executed on Ascend Chips. |
|
|
|
- GE supports several optimizations to reduce computation costs, e.g. operator fusion, parallel operation, data format transition. |
