CPU-time measurements for any program part whatever. Results of the62 ! measurements are output at the end of the run in local file CPU_MEASURES.63 ! 64 ! To measure the CPU-time (better to say the wallclock time) of a specific code65 ! segment, two calls of cpu_log have to be used as brackets in front and at the66 ! end of the segment:67 ! 68 ! CALL cpu_log( log_point(n), 'any identifier', 'start' )69 ! ... code segment ...70 ! CALL cpu_log( log_point(n), 'any identifier', 'stop' )71 ! 72 ! Parts of the code segment can be excluded from the measurement by additional73 ! call of cpu_log:74 ! 75 ! ... first segment to be measured76 ! CALL cpu_log( log_point(n), 'any identifier', 'pause' )77 ! ... oart of segment to be excluded from measurement78 ! CALL cpu_log( log_point(n), 'any identifier', 'continue' )79 ! ... second segment to be mesasured80 ! 81 ! n is an INTEGER within the interval [1,100] defining the id of the specific82 ! code segment, 'any identifier' is a string describing the code segment to be83 ! measured. It can be freely chosen and results will appear under this name in84 ! file CPU_MEASURES. ids can only be used once. If you like to do a85 ! measurement of a new part of the code, please look for an id which is unused86 ! ao far.87 ! 88 ! d3par-parameter cpu_log_barrierwait can be used to set an MPI barrier at the89 ! beginning of the measurement (modus 'start' or 'continue'), to avoid that90 ! idle times (due to MPI calls in the code segment, which are91 ! waiting for other processes to be finished) affect the measurements.92 ! If barriers shall not be used at all, a fourth, optional parameter has to be93 ! given:94 ! 95 ! CALL cpu_log( ..., ..., 'start', cpu_log_nowait )96 ! 97 ! Variable log_point should be used for non-overlapping code segments, and they98 ! should sum up to the total cpu-time required by the complete run.99 ! Variable log_point_s can be used for any other special (s) measurements.60 !> CPU-time measurements for any program part whatever.
