Ebo, Kent - what you are really touching upon here is the question of future middleware, i.e. NML/RCS replacement candidates which can act as remote HAL access too whatever we pick, this must be requirements-driven, and whatever comes up needs to be checked very thoroughly against all key requirements, nevermind the elegance of underlying idea - past experience helps but should not mislead one to overlook any of the must-have criteria. we discussed this before, but the must-haves of my requirements list include: - operating system independence (read as: a userland only affair, and available on non-*x platforms - anything in-kernel is a potential detriment) - multiple paradigms - plain messaging, publish/subscribe, remote procedure call - multiple language bindings available all this without extra coding - there is no manpower around to do that in case its missing A good method to judge a match is to start with an arbitrary non-Linux platform running the frontend, and then start counting the hoops to jump until you arrive at something working. Windows, IOS and Android make excellent starting points, lots of free bonus hoops included ;) The minimum-number-of-hoops vehicle will likely be declared as winner. -Michael ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: BUILD Helping you discover the best ways to construct your parallel projects. http://goparallel.sourceforge.net _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
