I am currently trying to implement local branching with multiple local trees. How can I implement this through calling CPLEX from Java?

is there anyway to invoke Parallel MIP Optimizer of CPLEX or its equivalent from the callable library?

Assuming that your machine allows multiple threads (has more than one core/processor), CPLEX will invoke the parallel MIP optimizer by default. This is true for all the APIs (including the callable library) as well as the interactive optimizer. The number of threads that CPLEX can invoke is limited the number of parallel threads that the machine can support (the number of cores/processors) and the IloCplex::Threads/CPX_PARAM_THREADS parameter setting. The default setting of this parameter is 0, which invokes the maximum number of threads that the machine can support, but the user is free to set it to a particular value (<= the number of cores/processor) as he may wish.
