| 10 | ! Module for timing statistics. Module is internal to the GSTATS package - |
|---|
| 11 | ! routines GSTATS, SUSTATS and STATS_OUTPUT. The logical switches are |
|---|
| 12 | ! re-initialized in SUMPINI |
|---|
| 13 | |
|---|
| 14 | ! LSTATS - TRUE for gathering timing statistics |
|---|
| 15 | ! LSTATSCPU - TRUE for gathering CPU timing statistics |
|---|
| 16 | ! LSYNCSTATS - TRUE for syncronization (call to barrier) at the |
|---|
| 17 | ! start of timing event |
|---|
| 18 | ! LDETAILED_STATS - TRUE for more detail in output |
|---|
| 19 | ! LSTATS_OMP - TRUE for gathering timing statistics on OpenMP regions |
|---|
| 20 | ! 1001-1999 |
|---|
| 21 | ! LSTATS_COMMS - TRUE for gathering detailed timing of Message passing |
|---|
| 22 | ! 501-1000 |
|---|
| 23 | ! NTRACE_STATS - max number of entries in trace |
|---|
| 24 | ! LTRACE_STATS - True for trace of all calls to gstats |
|---|
| 25 | ! LGSTATS_LABEL - True after GSTATS-labels have been set |
|---|
| 26 | ! JPMAXSTAT - max number of separate timers in gstats |
|---|
| 27 | ! JPOBCOUNT_BASE - first counter for obs types |
|---|
| 28 | ! NCALLS - number of times a timer has been switched on |
|---|
| 29 | ! TIMESUM - total time spent with timer on |
|---|
| 30 | ! TIMESQSUM - sum of the squares of times |
|---|
| 31 | ! TIMEMAX - max time of all calls |
|---|
| 32 | ! TIMESUMB - sum of times between previous timer was invoked and this |
|---|
| 33 | ! timer was switched on ( to be used for finding out which parts |
|---|
| 34 | ! of the code that is not being timed) |
|---|
| 35 | ! TIMELCALL - time when event was switched on or resumed |
|---|
| 36 | ! TTCPUSUM - total cpu time |
|---|
| 37 | ! TVCPUSUM - total vector cpu time |
|---|
| 38 | ! THISTIME - total accumulated time for this call to timing event (necessary |
|---|
| 39 | ! to be able to suspend and resume timer and still have it counted |
|---|
| 40 | ! as one timing event) |
|---|
| 41 | ! THISTCPU - as THISTIME but for CPU time |
|---|
| 42 | ! THISVCPU - as THISTIME but for vector CPU time |
|---|
| 43 | ! TTCPULCALL - as TIMELCALL but for CPU time |
|---|
| 44 | ! TVCPULCALL - as TIMELCALL but for vector CPU time |
|---|
| 45 | ! TIME_LAST_CALL - last time GSTATS was called |
|---|
| 46 | ! TIME_START - used for recording parallel startup time |
