   > I think this is causing MXNet to use the slow CentOS OpenMP instead of the bundled support.
   
   Another hypothesis is that the slowdown results from an interaction of the llvm openmp linked by mxnet + the gcc 7 openmp (?) provided by devtoolset 7 on centos. Let's try if the issue persists when only linking one openmp implementation.
