	89	! Description:
	90	! ------------
[1682]	91	!> CPU-time measurements for any program part whatever. Results of the
	92	!> measurements are output at the end of the run in local file CPU_MEASURES.
	93	!>
	94	!> To measure the CPU-time (better to say the wallclock time) of a specific code
	95	!> segment, two calls of cpu_log have to be used as brackets in front and at the
	96	!> end of the segment:
	97	!>
	98	!> CALL cpu_log( log_point(n), 'any identifier', 'start' )
	99	!> ... code segment ...
	100	!> CALL cpu_log( log_point(n), 'any identifier', 'stop' )
	101	!>
	102	!> Parts of the code segment can be excluded from the measurement by additional
	103	!> call of cpu_log:
	104	!>
	105	!> ... first segment to be measured
	106	!> CALL cpu_log( log_point(n), 'any identifier', 'pause' )
	107	!> ... oart of segment to be excluded from measurement
	108	!> CALL cpu_log( log_point(n), 'any identifier', 'continue' )
	109	!> ... second segment to be mesasured
	110	!>
	111	!> n is an INTEGER within the interval [1,100] defining the id of the specific
	112	!> code segment, 'any identifier' is a string describing the code segment to be
	113	!> measured. It can be freely chosen and results will appear under this name in
	114	!> file CPU_MEASURES. ids can only be used once. If you like to do a
	115	!> measurement of a new part of the code, please look for an id which is unused
	116	!> ao far.
	117	!>
	118	!> d3par-parameter cpu_log_barrierwait can be used to set an MPI barrier at the
	119	!> beginning of the measurement (modus 'start' or 'continue'), to avoid that
	120	!> idle times (due to MPI calls in the code segment, which are
	121	!> waiting for other processes to be finished) affect the measurements.
	122	!> If barriers shall not be used at all, a fourth, optional parameter has to be
	123	!> given:
	124	!>
	125	!> CALL cpu_log( ..., ..., 'start', cpu_log_nowait )
	126	!>
	127	!> Variable log_point should be used for non-overlapping code segments, and they
	128	!> should sum up to the total cpu-time required by the complete run.
	129	!> Variable log_point_s can be used for any other special (s) measurements.
