sandeep-krishnamurthy commented on issue #8219: Broadcasting ops are slow URL: https://github.com/apache/incubator-mxnet/issues/8219#issuecomment-380269179 * mx.sym.broadcast_add is used in Keras-MXNet project - https://github.com/awslabs/keras-apache-mxnet/blob/keras2_mxnet_backend/keras/backend/mxnet_backend.py#L3323 * This is a very crucial operator used in every network for adding bias. * We are seeing significantly slower performance with MXNet backend on CPUs. * Tried with setting OMP_NUM_THREADS. It did not change the performance. This means this is single threaded.
