ciyongch opened a new pull request #17707: [MKLDNN] Remove overhead of sg_mkldnn_fullyconnected op URL: https://github.com/apache/incubator-mxnet/pull/17707 ## Description ## This PR is mainly focus on removing the overhead of sg_mkldnn_fullyconnected especially in the case of channel-wise quantization mode (no much change for FP32 or tensor-wise quantization mode) described in https://github.com/apache/incubator-mxnet/issues/17705, via removing extra condition check in the current logic (weights version and calibrated data value), but leaving an ENV of `MXNET_MKLDNN_QFC_DYNAMIC_PARAMS` for the scenario of changing those values on the fly (we don't meet such usage but in case there is). ## Checklist ## ### Essentials ### Please feel free to remove inapplicable items for your PR. - [ ] The PR title starts with [MXNET-$JIRA_ID], where $JIRA_ID refers to the relevant [JIRA issue](https://issues.apache.org/jira/projects/MXNET/issues) created (except PRs with tiny changes) - [ ] Changes are complete (i.e. I finished coding on this PR) - [ ] All changes have test coverage: - Unit tests are added for small changes to verify correctness (e.g. adding a new operator) - Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore) - Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL) - [ ] Code is well-documented: - For user-facing API changes, API doc string has been updated. - For new C++ functions in header files, their functionalities and arguments are documented. - For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable - Check the API doc at https://mxnet-ci-doc.s3-accelerate.dualstack.amazonaws.com/PR-$PR_ID/$BUILD_ID/index.html - [ ] To the best of my knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change ### Changes ### - [ ] Feature1, tests, (and when applicable, API doc) - [ ] Feature2, tests, (and when applicable, API doc) ## Comments ## - If this change is a backward incompatible change, why must this change be made. - Interesting edge cases to note here @TaoLv @eric-haibin-lin @pengzhao-intel
