Enables distributed concurrent optimization, which can be used
to solve LP or MIP models on multiple machines.
A value of
n causes the
solver to create
n independent models, using different
parameter settings for each. Each of these models is sent to a
distributed worker for processing. Optimization terminates when the first
solve completes. Use the
WorkerPool parameter to
provide a distributed worker cluster.
By default, Gurobi chooses the parameter settings used for each independent solve automatically. You can create concurrent environments to choose your own parameter settings (refer to the concurrent optimization section for details). The intent of concurrent MIP solving is to introduce additional diversity into the MIP search. By bringing the resources of multiple machines to bear on a single model, this approach can sometimes solve models much faster than a single machine.
The distributed concurrent solver produces a slightly different
log from the standard solver, and provides different callbacks as
well. Please refer to the
Distributed Algorithms section of the
Gurobi Remote Services Reference Manual
for additional details.
