Hi,

Subject: [Coin-lpsolver] fast compile for CLP project?

Hi John;



I run the same LP model ( mps file ) on the executable CLP in the
directory 
of (Clp-1.3.3-win32-msvc8) and the CLP project in the directory 
\Clp-1.3.3\MSVisualStudio\v6\Clp (where there are some other example 
projects), but by using the same command "primals" or "solve" the
executable 
CLP gets the optimal solution in 762.322 seconds and the CLP project
under 
MSVisualStudio 6 took 193.912 seconds. Huge speed difference happened to
all 
the models I tried.



What environment did the CLP executable get compiled and built? I am
using 
the MS Visual Studio 6 under Windows XP. Will MS Visual Studio 8.0 give
the 
much faster speed or there are some special settings to the project? I
tried 
to change the optimization property to "maximize speed" in the project 
settings, however it said the project option /ZI and /O2 is
incompatible.  I 
tried some other settings in Debug info, but it said project option /GZ
and 
/O2 is incompatible.



I would really appreciate your help in getting the same speed as
executable 
CLP in order to write our own algorithm base on CLP to solve large scale

problems.



I am looking forward to hearing from you.





Thanks again.
