DISTRIBUTED ADA REAL-TIME SOFTWARE: DEVELOPMENT AND EXECUTION SUPPORT

THIS PROPOSAL DESCRIBES THE INVESTIGATION OF TECHNIQUES TO ACHIEVE EFFICIENT AND RELIABLE DISTRIBUTED PROCESSING USING THE ADA PROGRAMMING LANGUAGE AND SPECIFYING PARALLELISM BY UTILIZING THE ADA TASK MODEL. THE INTENT IS TO SUPPORT TRANSPARENT DISTRIBUTION WHICH WILL ALLOW SOFTWARE FUNCTIONALITY TO MIGRATE AMONG PROCESSORS WITHIN A LOCAL AREA NETWORK TO ACHIEVE PERFORMANCE AND FAULT TOLERANCE REQUIREMENTS. AREAS OF PARTICULAR CONCERN WHICH WILL BE ADDRESSED ARE: THE WAY IN WHICH TASKS AND DATA RE ASSOCIATED WITH PROCESSORS; A CONFIGURABLE NETWORK INTERFACE WHICH CAN SUPPORT THE REQUIREMENTS OF THE ADA RUNTIME; ND ACCESS TO SHARED DATA AMONG DISTRIBUTED TASKS. ALSO ADDRESSED ARE TOOLS TO SUPPORT DEBUGGING DISTRIBUTED SYSTEMS AS WELL AS TO MONITOR THE PERFORMANCE AND ASSIST IN PREDICTION OF OVERLOAD CONDITIONS.
