Numerous variants have been explored (e.g. [25]), and these approaches have been used in a wide range of applications. These benefits of object-oriented techniques and high level programming are commonly presumed to come at some loss in performance. For the past several years, we have explored combining high level programming with innovative implementation techniques to support both programmability and high performance. This high-level concurrent object-oriented programming model is embodied in ICC++ [9], which provides a global object namespace, implicit concurrency control, and non-binding concurrency. T..
