The output below is amazingly ugly and concerning. Matt answered your question, but in your build system, you should not be adding -DPETSC_CLANGUAGE_CXX; that is a configure-time option, not something that your code can change arbitrarily. Your makefile should include $PETSC_DIR/conf/variables (and conf/rules if you want, but not if you want to write your own rules). > mpirun -np 2 ./mpitest > > librdmacm: couldn't read ABI version. > librdmacm: assuming: 4 > CMA: unable to get RDMA device list > -------------------------------------------------------------------------- > [[44086,1],0]: A high-performance Open MPI point-to-point messaging module > was unable to find any relevant network interfaces: > > Module: OpenFabrics (openib) > Host: dornroeschen.igpm.rwth-aachen.de > > Another transport will be used instead, although this may result in > lower performance. > -------------------------------------------------------------------------- > librdmacm: couldn't read ABI version. > librdmacm: assuming: 4 > CMA: unable to get RDMA device list > Hello world from processor dornroeschen.igpm.rwth-aachen.de, rank 0 out > of 2 processors > Hello world from processor dornroeschen.igpm.rwth-aachen.de, rank 1 out > of 2 processors > [dornroeschen.igpm.rwth-aachen.de:128141] 1 more process has sent help > message help-mpi-btl-base.txt / btl:no-nics > [dornroeschen.igpm.rwth-aachen.de:128141] Set MCA parameter > "orte_base_help_aggregate" to 0 to see all help / error messages
