Hi,

I have written a MIP model that uses presolve, root relaxation and B&C for solving. I want to use this on a series of different data set, retrieving statistical information about the solving times for the different parts separately.

I can nowhere find anything about getting this information. I'm aware of writing a script to get the current time and by that, I can receive the total time for all processes. My question now is, if anybody can help me to get the times of the different solution parts separately.

Thanks a lot in advance.

Did you look at the OPL profiler already?

You can get more information on solve activities from there, in the IDE or from oplrun -profile.

The programmatic way for accessing profiler detailed information is not documented.

Frank,

is it possible to redirect the profiler info to a file?

Hi Frank,

thanks for the reply. It's exactly the information of the profiler, that I need. However, in my perfect world, I would like to access this information in a programmatic way - avoiding the extra programming work of retrieving the information from the oplrun's -profile. So, if anybody knows a trick for that, I'd be glad to hear it.

Cheers,
Dom

Hi Dom,

i'm not sure if this is what you are lookinng for, but what
I quite often do, is some profiling like

execute{
  var t0 = new Date();
  someFunction();
  var t1 = new Date();
  writeln(" Time for someFunction : ", t1-t0);
}

Hi Norbert,

Thanks for your reply. That is what I normally use as well. However, I can really only get this to work for the whole process of solving the MIP model in one session. If it would be possible to let the "someFunction()" be only presolve or root relaxation, then I could actually use that. But I don't know, how I would do that.

Cheers,
Dom

Okay - got your point.
As far as I know this is not possible.

Stil the open question: Is it possible to redirect the profiler
output to a file?

Thanks Norbert!

If anybody knows the answer to Norbert's question (redirecting the profiler output to a file), please post it here.

Cheers,

What you can do is manually copy the content to a file.
(Right mouse click in the profiler window - there should
be something like "Copy content ...".)

I am looking for an automatic way to redirect it!!

Any suggestions?
