|---|
| 46 | !> CPU-time measurements for any program part whatever. Results of the |
|---|
| 47 | !> measurements are output at the end of the run in local file CPU_MEASURES. |
|---|
| 48 | !> |
|---|
| 49 | !> To measure the CPU-time (better to say the wallclock time) of a specific code |
|---|
| 50 | !> segment, two calls of cpu_log have to be used as brackets in front and at the |
|---|
| 51 | !> end of the segment: |
|---|
| 52 | !> |
|---|
| 53 | !> CALL cpu_log( log_point(n), 'any identifier', 'start' ) |
|---|
| 54 | !> ... code segment ... |
|---|
| 55 | !> CALL cpu_log( log_point(n), 'any identifier', 'stop' ) |
|---|
| 56 | !> |
|---|
| 57 | !> Parts of the code segment can be excluded from the measurement by additional |
|---|
| 58 | !> call of cpu_log: |
|---|
| 59 | !> |
|---|
| 60 | !> ... first segment to be measured |
|---|
| 61 | !> CALL cpu_log( log_point(n), 'any identifier', 'pause' ) |
|---|
| 62 | !> ... oart of segment to be excluded from measurement |
|---|
| 63 | !> CALL cpu_log( log_point(n), 'any identifier', 'continue' ) |
|---|
| 64 | !> ... second segment to be mesasured |
|---|
| 65 | !> |
|---|
| 66 | !> n is an INTEGER within the interval [1,100] defining the id of the specific |
|---|
| 67 | !> code segment, 'any identifier' is a string describing the code segment to be |
|---|
| 68 | !> measured. It can be freely chosen and results will appear under this name in |
|---|
| 69 | !> file CPU_MEASURES. ids can only be used once. If you like to do a |
|---|
| 70 | !> measurement of a new part of the code, please look for an id which is unused |
|---|
| 71 | !> ao far. |
|---|
| 72 | !> |
|---|
| 73 | !> runtime_parameters-parameter cpu_log_barrierwait can be used to set an MPI |
|---|
| 74 | !> barrier at the beginning of the measurement (modus 'start' or 'continue'), |
|---|
| 75 | !> to avoid that idle times (due to MPI calls in the code segment, which are |
|---|
| 76 | !> waiting for other processes to be finished) affect the measurements. |
|---|
| 77 | !> If barriers shall not be used at all, a fourth, optional parameter has to be |
|---|
| 78 | !> given: |
|---|
| 79 | !> |
|---|
| 80 | !> CALL cpu_log( ..., ..., 'start', cpu_log_nowait ) |
|---|
| 81 | !> |
|---|
| 82 | !> Variable log_point should be used for non-overlapping code segments, and they |
|---|
| 83 | !> should sum up to the total cpu-time required by the complete run. |
|---|
| 84 | !> Variable log_point_s can be used for any other special (s) measurements. |
