displaying total CPU time

[Yasin053]

Hi,
I would like to record total CPU time of an algorithm in which an LP is solved a number of times. The commands such as _ampl_user_time and _ampl_time did not work for this purpose. What command should I use to display total CPU run time?
Thanks,

Here are three functions to calculate total time;


_total_solve_system_time     , for system cpu seconds used by all
solve commands,
_total_solve_user_time       , for user cpu seconds used by all solve
commands,
_total_solve_time            ,  _total_solve_system_time  +
_total_solve_user_time

check page 496 of the AMPL book, second edition

For a run time of about 90 sec., _total_solve_time is 7.9375, which does not make sense. I think the reason is due to solving an LP multiple times...

When an LP is solved only once in the code, _ampl_time(which is _ampl_system_time + _ampl_user_time) gives me total CPU time.
I was wondering whether someone faced the same issue with the code in which an LP is solved multiple times (as high as 50).
Thanks,
