....of the Comandos platform are briefly introduced below: An object model, which provides a conceptual model of a distributed environment, encompassing both computation and data management. A programming environment which supports the concepts of the model through various language as C and Eiffel [3], or directly using the Comandos object oriented language[9] A distributed object system providing the adequate support to the programming environment (see [1] and [6] Common services, built as normal objects, for symbolic naming, management of user defined types and complex objects, ....

....global objects at run time. Emerald exploits the call by move parameter passing mode. However, much of the work is left to the Emerald compiler as it must decide which objects are passed using the call by move mode. We wanted to keep the decisions generic and independent of the language. Amadeus [22] is very similar to IK, since they share the same model and general architecture defined in the Comandos project. However, they differ both at the language and implementation levels. New keywords were added to the language in Amadeus to express 4 OBJECT NAMING 6 persistence and distribution, ....

....co operating nodes. In designing the Tigger Cub the basic components that are necessary for the Tigger distributed object support platform were identified. These components are the kernel components necessary to support a subset of the Amadeus generic run time [20] and language specific run times [22, 24, 58]. The subset of the run times that must be supported is the subset that provides distributed object support. Other features such as persistence and security were also considered and the components of the Tigger Cub were designed so that other components can be integrated through small changes to ....

We wanted to keep the decisions generic and independent of the language. Within the Comandos project Guide (Balter et al. 1991) Amadeus (Cahill et al. 1990) and IK share the same model and general architecture, however, they differ both at the language and implementation levels.

....to the object. Our RTHs are untyped surrogates that can be generated and reused regardless of the object type they 4 ARCHITECTURE AND IMPLEMENTATION OF IK 8 represent. This makes pointer swizzling a much faster operation than in systems that use proxies or typed surrogates [Shapiro 89,Wilson 91,Cahill 90] In fact, swizzling from global references to pointers to typed proxies may be a very expensive operation. It requires determining the type or class of the global reference, mapping the corresponding proxy class if necessary, and creating a new proxy for the object. All this work is wasted if ....

....simpler and, at the same time, keep the decisions independent of the language. 2 For example, in figure 2 the beforeUnmap method prevents the lock object to be written to disk, and the afterMap method initializes the lock reference to a new lock object. 7 CONCLUSIONS 17 Like IK, Amadeus [Cahill 90] was developed within the Comandos project. Although sharing the same model and general architecture, they differ at both the language and implementation level. New keywords were added to the language in Amadeus to express persistence and distribution, whereas we decided to use inheritance and ....
