	72	! Description:
	73	! ------------
[1682]	74	!> CPU-time measurements for any program part whatever. Results of the
	75	!> measurements are output at the end of the run in local file CPU_MEASURES.
	76	!>
	77	!> To measure the CPU-time (better to say the wallclock time) of a specific code
	78	!> segment, two calls of cpu_log have to be used as brackets in front and at the
	79	!> end of the segment:
	80	!>
	81	!> CALL cpu_log( log_point(n), 'any identifier', 'start' )
	82	!> ... code segment ...
	83	!> CALL cpu_log( log_point(n), 'any identifier', 'stop' )
	84	!>
	85	!> Parts of the code segment can be excluded from the measurement by additional
	86	!> call of cpu_log:
	87	!>
	88	!> ... first segment to be measured
	89	!> CALL cpu_log( log_point(n), 'any identifier', 'pause' )
	90	!> ... oart of segment to be excluded from measurement
	91	!> CALL cpu_log( log_point(n), 'any identifier', 'continue' )
	92	!> ... second segment to be mesasured
	93	!>
	94	!> n is an INTEGER within the interval [1,100] defining the id of the specific
	95	!> code segment, 'any identifier' is a string describing the code segment to be
	96	!> measured. It can be freely chosen and results will appear under this name in
	97	!> file CPU_MEASURES. ids can only be used once. If you like to do a
	98	!> measurement of a new part of the code, please look for an id which is unused
	99	!> ao far.
	100	!>
	101	!> d3par-parameter cpu_log_barrierwait can be used to set an MPI barrier at the
	102	!> beginning of the measurement (modus 'start' or 'continue'), to avoid that
	103	!> idle times (due to MPI calls in the code segment, which are
	104	!> waiting for other processes to be finished) affect the measurements.
	105	!> If barriers shall not be used at all, a fourth, optional parameter has to be
	106	!> given:
	107	!>
	108	!> CALL cpu_log( ..., ..., 'start', cpu_log_nowait )
	109	!>
	110	!> Variable log_point should be used for non-overlapping code segments, and they
	111	!> should sum up to the total cpu-time required by the complete run.
	112	!> Variable log_point_s can be used for any other special (s) measurements.
