If the program is run using the test input files supplied with DPI, the energy error should oscillate around 1E-7 and the angular momentum error varying between 1E-13 and 1E-14 (the behaviour of the latter can vary depending on the hardware and the compiler due to the actual precision of the computations and the way rounding errors are handled).
