In $PETSC_DIR/$PETSC_ARCH/lib/petsc/conf/configure.log you should be able to see which options were used in PETSc's configure. If --with-64-bit-indices=1 is not there, ask the sysadmin to create another PETSc module with this option. Alternatively, configure it yourself from source with the same options adding --with-64-bit-indices=1
