Concurrent optimizer

Describes conditions favoring the concurrent optimizer.

The concurrent optimizer launches distinct optimizers in multiple threads. When the concurrent optimizer is launched on a single-threaded platform, it calls the dual simplex optimizer. In other words, choosing the concurrent optimizer makes sense only on a multiprocessor computer where threads are enabled. For more information about the concurrent optimizer, see Multithreaded parallel optimizers, especially Concurrent optimizer in parallel.

Tip: Crossover in concurrent optimization is incompatible with an LP callback due to considerations about thread-safety.
