  • If you are encountering segmentation faults from PMC, try add the environmental variable OMP_NUM_THREADS=${MAX_THREADS} (replace ${MAX_THREADS} with the maximum number of threads available on your machine) in your current shell. You can also just prepend OMP_NUM_THREADS=${MAX_THREADS} when running your executable.

  • When using the MATLAB wrapper with MATLAB on terminal (-nojvm option enabled), you might encounter errors similar to this:

    /usr/local/MATLAB/R2019a/bin/glnxa64/MATLAB: symbol lookup error: /opt/intel/compilers_and_libraries_2019.4.243/linux/mkl/lib/intel64_lin/libmkl_vml_avx2.so: undefined symbol: mkl_serv_getenv.

    One way to get around this is to run the following command in the environment where you start MATLAB:

    export LD_PRELOAD=/opt/intel/mkl/lib/intel64/libmkl_intel_lp64.so:/opt/intel/mkl/lib/intel64/libmkl_gnu_thread.so:/opt/intel/mkl/lib/intel64/libmkl_core.so

    You may need to change the paths according to your MKL installation.

  • If you see errors similar to: ./teaser_cpp_ply: error while loading shared libraries: libpmc.so: cannot open shared object file: No such file or directory, you need to run sudo ldconfig after installation.
