[petsc-users] Configuring PETSc with OpenMPI

[Balay, Satish]

Configure Options: --configModules=PETSc.Configure --optionsModule=config.compilerOptions PETSC_ARCH=linux-cumulus-hpc --with-cc=gcc --with-fc=gfortran --with-cxx=g++ --with-mpi-dir=/usr/local/depot/openmpi-3.1.1-gcc-7.3.0/bin/ --download-parmetis --download-metis --download-ptscotch --download-superlu_dist --download-mumps --with-scalar-type=complex --with-debugging=no --download-scalapack --download-superlu --download-fblaslapack=1 --download-cmake

' --with-cc=gcc --with-fc=gfortran --with-cxx=g++' prevents usage of mpicc etc - so remove these options when using with-mpi-dir

Or use:

--with-cc=/usr/local/depot/openmpi-3.1.1-gcc-7.3.0/bin/mpicc etc..
