!     ------------------------------------------------------------------
! Module for timing statistics. Module is internal to the GSTATS package -
! routines GSTATS, SUSTATS and STATS_OUTPUT. The logical switches are
! re-initialized in SUMPINI

! LSTATS - TRUE for gathering timing statistics
! LSTATSCPU - TRUE for gathering CPU timing  statistics
! LSYNCSTATS - TRUE for syncronization (call to barrier) at the 
!              start of timing event
! LDETAILED_STATS - TRUE for more detail in output
! LSTATS_OMP - TRUE for gathering timing statistics on OpenMP regions
!                 1001-1999
! LSTATS_COMMS - TRUE for gathering detailed timing of Message passing
!                 501-1000
! NTRACE_STATS    - max number of entries in trace
! LTRACE_STATS    - True for trace of all calls to gstats
! LGSTATS_LABEL   - True after GSTATS-labels have been set
! JPMAXSTAT - max number of separate  timers in gstats
! JPOBCOUNT_BASE - first counter for obs types
! NCALLS - number of times a timer has been switched on
! TIMESUM - total time spent with timer on
! TIMESQSUM - sum of the squares of times
! TIMEMAX - max time of all calls
! TIMESUMB - sum of times between previous timer was invoked and this
!            timer was switched on ( to be used for finding out which parts
!            of the code that is not being timed)
! TIMELCALL - time when event was switched on or resumed
! TTCPUSUM - total cpu time
! TVCPUSUM - total vector cpu time
! THISTIME - total accumulated time for this call to timing event (necessary
!            to be able to suspend and resume timer and still have it counted
!            as one timing event)
! THISTCPU - as THISTIME but for CPU time
! THISVCPU - as THISTIME but for vector CPU time
! TTCPULCALL - as TIMELCALL but for CPU time
! TVCPULCALL - as TIMELCALL but for vector CPU time
! TIME_LAST_CALL - last time GSTATS was called
! TIME_START - used for recording parallel startup time
