https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/mkl-set-num-threads-doesn-t-work/m-p/1149101#M26952 <P>Hello everyone!</P><P>I am using MxNet library with MKL support. I need my mxnet predictor use only one thread for calculations. For this purpose I used OMP_NUM_THREADS = 1 environment variable. So it works fine for me. Then I read in MKL documentation that there is a special function mkl_set_num_threads() for that and that it's equivalent to OMP_NUM_THREADS. So I removed this env variable and called mkl_set_num_threads()&nbsp;instead before creating and using predictor.&nbsp;But there was no effect - my predictor still used more than one thread for calculations and it looks like he ignored this function. Maybe I don't know something. Any ideas? Thanks.</P> Fri, 08 Feb 2019 18:43:35 GMT Korolev__Roman 2019-02-08T18:43:35Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/mkl-set-num-threads-doesn-t-work/m-p/1149101#M26952 <P>Hello everyone!</P><P>I am using MxNet library with MKL support.
