 Hello everybody,

 I'm sorry to bother with this ticket, but I didn't find any forum where I
 can question a CBC developer.

 We're using with my team the CBC solver on a big logistic problem (around
 4 millions continuous and discrete variables).

 We observed that when we launch the solving directly from command lines it
 is way quicker than from our project execution (c++).

 In both cases we would like first to know how can we activate the
 multithreading option because for the moment it runs with only one thread.
 I read that it could be a problem of the way we compiled the solver ?!

 Then, is someone know if there is any option we can activate in our c++
 project in order to use the same algorithms as command line ones (in our
 project "cgl" and "cbc" algorithms are launched whereas in command line
 "clp" is).

 I would be very grateful is someone can help.

 Regards,

 Leslie
