| # Release 0.1.0-alpha | |||||
| # Release 0.2.0-alpha | |||||
| 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. | |||||
| ## Main features | |||||
| ## 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. | |||||
| ## Thanks to our Contributors | |||||
| Thanks goes to these wonderful people: Wang Cong, Tianchun Xu, Haoran Yang. | |||||
| - Debugging | |||||
| - GE supports data dump and graph dump for debugging. | |||||
| - GE provides profiling tools to thoroughly analyze the speed performances. | |||||
| Contributions of any kind are welcome! | |||||
