alternative host
Imported issue: Initially reported by F. Morain in https://gforge.inria.fr/tracker/?group_id=2065&aid=16163
In some cases, typically on clusters, one cannot use the front-end to perform any operation, or at least operations that could consume some CPU time. Would it possible to have a mechanism to declare that the starting host is some node, different from the front end? It could be also useful to enable one to also have a different starting node for filtering/linalg.
