[petsc-users] petsc without MPI

[Balay, Satish]

And I see from configure.log - you are using the correct option.

>>>>>>>
Configure Options: --configModules=PETSc.Configure --optionsModule=config.compilerOptions --with-scalar-type=real --with-x=0 --with-hdf5=0 --with-single-library=1 --with-shared-libraries=0 --with-log=0 --with-mpi=0 --with-clanguage=C++ --with-cxx-dialect=C++11 --CXXFLAGS="-fopenmp -fPIC" --CFLAGS="-fopenmp -fPIC" --with-fortran=0 --FFLAGS="-fopenmp -fPIC" --with-64-bit-indices=0 --with-debugging=0 --with-cc=gcc --with-fc=gfortran --with-cxx=g++ COPTFLAGS= CXXOPTFLAGS= FOPTFLAGS= --download-metis=0 --download-superlu_dist=0 --download-parmetis=0 --with-valgrind-dir=/apps/brown/valgrind/3.13.0_gcc-4.8.5 --download-mumps=1 --with-mumps-serial=1 --with-fortran-kernels=0 --with-blaslapack-lib="-Wl,-rpath,/apps/cent7/intel/compilers_and_libraries_2017.1.132/linux/mkl/lib/intel64  -L/apps/cent7/intel/compilers_and_libraries_2017.1.132/linux/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_gnu_thread -lmkl_core " --with-blacs-lib=/apps/cent7/intel/compilers_and_libraries_2017.1.132/linux/mkl/lib/intel64/libmkl_blacs_intelmpi_lp64.so --with-blacs-include=/apps/cent7/intel/compilers_and_libraries_2017.1.132/linux/mkl/include --with-scalapack=0

And configure completed successfully. What issue are you encountering? Why do you think its activating MPI?
