performance on CPU
sandeep-krishnamurthy opened a new issue #10881: mx.sym.dot() performance on CPU
URL: https://github.com/apache/incubator-mxnet/issues/10881
We are using mx.sym.dot() operator in Keras heavily. We observe CPU performance is suspiciously slower. On profiling a RNN LSTM example, the observation is as shown below.
dot() operator is contributing to 90% of computation time. Is there any performance implication of mx.sym.dot() operator on CPU?
We are using mxnet-mkl-dnn build, is the operator using gemm operations under the hood?
@anirudh2290 @zheng-da - Any suggestions / comments?
