The answer is a qualified "yes". We have been successfully using Cbc to simultaneously solve multiple different problems in different threads by creating a CbcModel object and calling the branchAndBound()  method. Using the wrappers in CbcSolver.cpp does not seem to be thread-safe. Calling Cbc this way only works for solving one MILP at a time (though it is possible to use multiple threads to solve that single MILP). I don't recall the precise reason for this.

Cheers,

Ted

Hi,
Is the cbc library (and the clp) thread safe ?
What I mean is :  Can two different threads solve (two different problems) simultaneously ?
Thanks,
Alon
