cjolivier01 commented on issue #17641: OpenMP Error URL: https://github.com/apache/incubator-mxnet/issues/17641#issuecomment-590527708 Another thing to note is that ompenmp with llvm also installs libgomp.so as a symlink to libomp.so, so there's a good chance that libomp.so will be loaded no matter what, depending upon whether a system had clang/openmp installed at all and where that is in the link order. So unless I am missing some clever logic, what mkl doing with its dynamic loading is a cause for concern. Also of note, clang seems to also put a symlink to libiomp5: ```bash [chriso@chriso-ripper:~/src/mxnet (master)]ls -l /usr/local/lib/lib*omp*.so* lrwxrwxrwx 1 root root 9 Feb 20 14:37 /usr/local/lib/libgomp.so -> libomp.so lrwxrwxrwx 1 root root 9 Feb 20 14:37 /usr/local/lib/libiomp5.so -> libomp.so -rw-r--r-- 1 root root 953376 Feb 20 14:36 /usr/local/lib/libomp.so -rw-r--r-- 1 root root 66072 Feb 20 14:36 /usr/local/lib/libomptarget.so ``` SO it seems link order is important?
