49 | !> CPU-time measurements for any program part whatever. Results of the |
---|
50 | !> measurements are output at the end of the run in local file CPU_MEASURES. |
---|
51 | !> |
---|
52 | !> To measure the CPU-time (better to say the wallclock time) of a specific code |
---|
53 | !> segment, two calls of cpu_log have to be used as brackets in front and at the |
---|
54 | !> end of the segment: |
---|
55 | !> |
---|
56 | !> CALL cpu_log( log_point(n), 'any identifier', 'start' ) |
---|
57 | !> ... code segment ... |
---|
58 | !> CALL cpu_log( log_point(n), 'any identifier', 'stop' ) |
---|
59 | !> |
---|
60 | !> Parts of the code segment can be excluded from the measurement by additional |
---|
61 | !> call of cpu_log: |
---|
62 | !> |
---|
63 | !> ... first segment to be measured |
---|
64 | !> CALL cpu_log( log_point(n), 'any identifier', 'pause' ) |
---|
65 | !> ... oart of segment to be excluded from measurement |
---|
66 | !> CALL cpu_log( log_point(n), 'any identifier', 'continue' ) |
---|
67 | !> ... second segment to be mesasured |
---|
68 | !> |
---|
69 | !> n is an INTEGER within the interval [1,100] defining the id of the specific |
---|
70 | !> code segment, 'any identifier' is a string describing the code segment to be |
---|
71 | !> measured. It can be freely chosen and results will appear under this name in |
---|
72 | !> file CPU_MEASURES. ids can only be used once. If you like to do a |
---|
73 | !> measurement of a new part of the code, please look for an id which is unused |
---|
74 | !> ao far. |
---|
75 | !> |
---|
76 | !> runtime_parameters-parameter cpu_log_barrierwait can be used to set an MPI |
---|
77 | !> barrier at the beginning of the measurement (modus 'start' or 'continue'), |
---|
78 | !> to avoid that idle times (due to MPI calls in the code segment, which are |
---|
79 | !> waiting for other processes to be finished) affect the measurements. |
---|
80 | !> If barriers shall not be used at all, a fourth, optional parameter has to be |
---|
81 | !> given: |
---|
82 | !> |
---|
83 | !> CALL cpu_log( ..., ..., 'start', cpu_log_nowait ) |
---|
84 | !> |
---|
85 | !> Variable log_point should be used for non-overlapping code segments, and they |
---|
86 | !> should sum up to the total cpu-time required by the complete run. |
---|
87 | !> Variable log_point_s can be used for any other special (s) measurements. |
