Description

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
