Abstract Split execution is a common model for providing afriendly environment on a foreign machine. In this model, a remotely executing process sends some or all of its systemcalls back to a home environment for execution. Unfortunately, hand-coding split execution systems for experimen-tation and research is difficult and error-prone. We have built a tool, Bypass, for quickly producing portable and cor-rect split execution systems for unmodified legacy applications. We demonstrate Bypass by using it to transparentlyconnect a POSIX application to a simple data staging system based on the Globus toolkit. 1.

be minimized by deploying a kernel agent called a packet filter, which discards unwanted packets as early as possible. The original Unix packet filter was designed around a stack-based filter evaluator that performs sub-optimally on current RISC CPUs. The BSD Packet Filter (BPF) uses a new, registerbased

VM called a virtual appliance. Because of the semantics gap in Hardware Abstraction Layer (HAL)-based virtualization, a physical machine’s virtual appliance requires the support of per-VM in-guest agents to perform VM-specific operations such as kernel data structure access and modification

-measurement of these issues are subject to attacks that are able to exploit the vulnerabilities of the operating system kernel (OS kernel). To protect agents and agencies against such risks, we proposed a novel approach that isolates the OS kernel and limit modifications to the agency system in the physical memory space. Our

We investigate the issue of designing a kernel programming language for Mobile Computing and describe Klaim, a language that supports a programming paradigm where processes, like data, can be moved from one computing environment to another. The language consists of a core Linda with multiple tuple

Abstract. The paper addresses the development and use of Grid middleware and the use of distributed resources for interactive visualisation of simulated data within a dedicated problem-solving environment. We developed an agent-oriented architecture, the Interactive Simulation System Conductor (ISS

of organizational reflection which uses the same conceptual model to describe systemlevel tasks such as remote communication and migration of agents. Finally, we briefly describe a platform, called MADKIT, based on this model. It relies on a minimal agent kernel with platform-level services implemented as agents

JavaSeal is a secure mobile agent kernel that provides a small set of abstractions for constructing agent applications. This paper describes the design of these abstractions and their implementation. We address the limitations of the Java security model that had to be overcome, and then present a

We investigate and discuss safety and privacy preserving properties of a game-theortic based coalition algorithm KCA for forming kernel stable coalitions among information agents in face of imperfect information on actual coalition values, and changing agent society. In addition, we analyze
