Conference paper (other academic/artistic)abstract
- The requirements and specification of a protocol for low level communication between the run-time systems in a distributed Ada environment is presented. This allows an Ada system to be separated into software resources and run-time controllers. Calls to the local run-time system of a node, concerning task management, are transformed into remote calls to the controller, that schedules all tasks in the application. The calls to the run-time system together with all messages, requests and replies, that are triggered as a consequence, are described. The controller will be implemented in hardware separate from the processors. Communication between processors and controllers are by means of high speed (Gigabit) networks. In the proposed system, partitioning and distribution of Ada programs can fully utilize the inherent and strong type checking in Ada.

Distribution of Tasks Within a Centrally Scheduled Local Area Network

Conference paper (other academic/artistic)abstract
- Distribution of a single Ada program on a local area network is accomplished by partitioning the run-time system into two parts. A central scheduling module is responsible for task management. Distributed run-time executives handle context switches and remote entry calls; however all activities are supervised by the scheduler. The scheduler can be implemented in hardware in order to achieve high efficiency. A network based on optical fibers is necessary due to the high speed required for system calls. Asynchronous Transfer Mode is suggested as the protocol for the communication. We describe an implementation of the divided run-time system on an Ethernet network, using MC68030-based micro computers as targets and an Ada program executing on a Rational host as the scheduler.
