Restarting execution message

Does anyone know about the ‘Restarting execution’ message after the complete solving a model? What does it do?

I’d like to disable this step to save time and memory. Could you please help me?

The message appears as follows:

Optimal solution found.

Objective : 399121.740006



— Restarting execution

— Untitled_5.gms(760) 37 Mb

— Reading solution for model PSCM_main

— Untitled_5.gms(760) 40 Mb

— Putfile opts C:\Users\H\Documents\gamsdir\projdir\cplex.opt

*** Status: Normal completion

— Job Untitled_5.gms Stop 10/19/14 18:10:07 elapsed 0:00:03.862





Thanks in advance

Hi,

GAMS can call the solver in different ways. Please find documentation about this at http://www.gams.com/mccarl/mccarlhtml/solvelink.htm. So with solvelink=1,2,5 you will prevent the restart.

Hope this helps,

Hi

Dear Michael

Many thanks for your useful comment.

Actually I am using solvelink=3 in a Grid computing environment. However, I did not understand what does mean that message. My model is a large scale problem and I try to solve it iteratively. However, I found that the restart process take considerable time which is undesirable step for my model.

Would you please describe that message performance or application? Can I remove this step, Restarting execution, in a Grid computing environment or it is necessary and unavoidable process in a Grid computing environment (solvelink=3).

Best regards;

Hossein

Hi,

While you only send a small piece of your log I have my doubts that you are using solvelink=3 for this solve. With solvelink=3 you see messages like:

— Generating LP model transport
— trnsgrid.gms(77) 4 Mb
— LOOPS s = 1
— 6 rows 7 columns 19 non-zeroes
— Submitting model transport with handle grid145000001
— Executing after solve: elapsed 0:00:00.064

and

— GDXin=C:\tmp\225c\grid145000001\gmsgrid.gdx
— Removed handle grid145000001

Solve statements with solvelink=3 have no “Restarting execution”. Please try model trnsgrid from the GAMS Model Library (http://gams.com/modlib/libhtml/trnsgrid.htm). You should post you entire log and also your model.

Many thanks for your comment. I had two different model and each is solved with different solvelink. I had ignored not to display the message in that model with solvelink=3.
