Objective

The objective of CHAMELEON was to build a dynamic software migration system. The purpose of this system is to enable the migration and execution of active objects throughout a heterogeneous computer network. The elements of the system are an abstract common machine, an abstract common machine environment and the network.
This project was associated with project 1261, HTDS.
The objective was to build a dynamic software migration system, to enable the migration and execution of active objects throughout a heterogeneous computer network. The elements of the system are an abstract common machine, an abstract common machine environment and the network. The starting point for this project was the AMBER machine, an intermediate machine model. The abstract machine is a model which reflects target machine and programming language concepts to support the portability of programs. Two intermediate machine models, IACM and HARP, were proposed and examined by the partners. HARP is a general purpose machine model and makes no assumptions about the supported languages; IACM is more closely modelled on the AMBER machine. These designs differ in the ease with which they could support the languages C and SCHEME. Models of both abstract machines were developed within the project. Demonstrations of software migration in an homogeneous environment using abstractions of 2 intermediate machine models were given.

Two intermediate machine mode ls, IACM and HARP, were proposed and examined by the partners. HARP is a general purpose machine model and makes no assumptions about the supported languages; IACM is more closely modelled on the AMBER machine. These designs differ in the ease with which they could support the languages "C" and SCHEME. Models of both abstract machines were developed within the project.
Demonstrations of software migration in a homogeneous environment using abstractions of two intermediate machine models were given.
Exploitation
The productivity gains will allow users to undertake important projects which would be prohibitively time consuming with existing technology. For example, a software porting task which nowadays could take several months, could conceivably be accomplished in, at most, one morning. Therefore, this project is expected to greatly improve productivity and to drastically reduce the cost of moving software. The concepts being developed could also be exploited in networks where programs could be moved around the network and activated at remote nodes.
