[Cbc] Using parallel branch & bound

[Sam Mathew]

Hi Jesse,

In order to use parallel, you need to do this while configuring during
installation of Cbc.

The right step then would be (supposing you are in the build directory,
within the directory where CBC has been downloaded using SVN)

../configure --enable-cbc-parallel
make
make install

It might help if you look at the fourth option on the following:

Then you can use the parallel version within C++.

JuMP has it pre-configured to run parallel, so you did not need to do it
there.

Regards,

Sam
