I see you’re still using a petsc that uses the reference blas/lapack and ethernet instead of Intel OPA:

Configure Options: --configModules=PETSc.Configure --optionsModule=config.compilerOptions --with-cc++=clang++ COPTFLAGS="-g -mavx2" CXXOPTFLAGS="-g -mavx2" FOPTFLAGS="-g -mavx2" --download-mpich=1 --download-hypre=1 --download-metis=1 --download-parmetis=1 --download-c2html=1 --download-ctetgen --download-p4est=1 --download-superlu_dist --download-superlu --download-triangle=1 --download-hdf5=1 --download-fblaslapack=1 --download-zlib --with-x=0 --with-debugging=0 PETSC_ARCH=skx-cxx-O --download-chaco --with-viewfromoptions=1
Working directory: /home1/04906/bonnheim/petsc-3.9.3

I’ve alerted you guys about this months ago.

Victor.
