The veriication of multi agent systems is an important and diicult task. Though much work is spent on veriication in concurrency theory only few results and tools are used in multi-agent systems. In this paper, we investigate how CCS, the calculus for concurrent systems, may contribute to the veriication of multi-agent systems. We review an architecture for a diagnosis agent and show how the to...

These brief notes explore the requirements and design issues surrounding concurrency control in groupware – software with which several users, often geographically separated, collaborate on a shared task such as document writing. The next section gives an overview of groupware. We then give requirements and design issues, and go on to discuss how traditional concurrency control techniques such ...

We present here the ExM (extreme-scale many-task) programming and execution model as a practical solution to the challenges of programing the higher-level logic of complex parallel applications on current petascale and future exascale computing systems. ExM provides an expressive, high-level functional programming model that yields massive concurrency through implicit, automated parallelism. It...

According to rapid assessment requirement of system protection control strategy adaptability in future operation mode, combining with application status distributed computing for power security and stability analysis, based on design idea asynchronism concurrency, this paper proposes a multi-scheme concurrent framework suitable coarse-grained case parallelism. By the way multi-data section para...
