  The Global-Local non-invasive coupling is an improvement of the submodeling
technique, which permits to locally enhance structure computations by
introducing patches with refined models and to take into accounts all the
interactions. In order to circumvent its inherently limited computational
performance, we propose and implement an asynchronous version of the method.
The asynchronous coupling reduces the dependency on communications, failures,
and load imbalance. We present the theory and the implementation of the method
in the linear case and illustrate its performance on academic cases inspired by
actual industrial problems.
