This paper describes an execution model being developed for distributed object-oriented in a message-passing multiple-instruction/multiple-data-stream (MIMD) environment. The objective is to execute an object-oriented program as concurrently as possible. Some opportunities for concurrency can be identified explicitly by the programmer. Others can be(More)
We present an overview of a model of execution for concurrent object-oriented general-purpose computation, and a run-time system---SAM---that supports the model of execution. The basic model, which is transparent to the programmer, uses data-driven synchronization and speculative computation to obtain concurrency, and rollback to ensure correctness. We(More)
The Jobstream Separator (JSS) has been proposed to automate the costly, inefficient, and inconvenient manual process utilized to "change colors" (security levels) at AF WWMCCS sites. The JSS would provide complete isolation among WWMCCS users and data at differing levels by introducing a secure, centralized, certifiably correct, minicomputet system to(More)
MITRE'S Evolvable Real-Time Comma& Control, and Communications (C3) project funa' ed under the Air Force Mission Oriented Investigation and Experimentation (MOIE) program attempts to develop an approach that would enable current real-time systems to evolve into the systems of the future. The project has chosen Airbonze Warning and Control System (AWACS) as(More)
MITRE — through its Future Generation Computer Architectures program — has conducted research in parallel computing since 1983 [2-5.7]. Our research is currently directed toward operating systems for massive distributed-memory MIMDs running general-purpose, object-oriented programs. Scalability and reliability are central concerns in our(More)
