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.

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.

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;

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,

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

Thanks in advance
