./configure -cc=mpicc -c++=mpicxx -mpi -bfd=download -unwind=download &&
make install
export PATH=<tau dir>/x86_64/bin:$PATH
Build and run PETSc example with TAU:
cd $PETSC_DIR/src/snes/tutorials
make ex56
mpirun -n 4 tau_exec ./ex56 <args>
This should produce 4 profile...* files with profile data that can be
