71	! Description:
72	! ------------
73	!> CPU-time measurements for any program part whatever. Results of the measurements are output at
74	!> the end of the run in local file CPU_MEASURES.
75	!>
76	!> To measure the CPU-time (better to say the wallclock time) of a specific code segment, two calls
77	!> of cpu_log have to be used as brackets in front and at the end of the segment:
78	!>
79	!> CALL cpu_log( log_point(n), 'any identifier', 'start' )
80	!> ... code segment ...
81	!> CALL cpu_log( log_point(n), 'any identifier', 'stop' )
82	!>
83	!> Parts of the code segment can be excluded from the measurement by additional call of cpu_log:
84	!>
85	!> ... first segment to be measured
86	!> CALL cpu_log( log_point(n), 'any identifier', 'pause' )
87	!> ... oart of segment to be excluded from measurement
88	!> CALL cpu_log( log_point(n), 'any identifier', 'continue' )
89	!> ... second segment to be mesasured
90	!>
91	!> n is an INTEGER within the interval [1,100] defining the id of the specific code segment,
92	!> 'any identifier' is a string describing the code segment to be measured. It can be freely chosen
93	!> and results will appear under this name in file CPU_MEASURES. ids can only be used once. If you
94	!> like to do a measurement of a new part of the code, please look for an id which is unused so far.
95	!>
96	!> runtime_parameters-parameter cpu_log_barrierwait can be used to set an MPI barrier at the
97	!> beginning of the measurement (modus 'start' or 'continue'), to avoid that idle times (due to MPI
98	!> calls in the code segment, which are waiting for other processes to be finished) affect the
99	!> measurements.
100	!> If barriers shall not be used at all, a fourth, optional parameter has to be
101	!> given:
102	!>
103	!> CALL cpu_log( ..., ..., 'start', cpu_log_nowait )
104	!>
105	!> Variable log_point should be used for non-overlapping code segments, and they should sum up to
106	!> the total cpu-time required by the complete run.
107	!> Variable log_point_s can be used for any other special (s) measurements.
