A Distributed Kernel for Virtual Time Driven Applications

The advent of distributed m e m o r y parallel muchines turns feasible the design and implementat ion of dedicated environments for distributed applications. This puper addresses such a realization b y present iny a distributed kernel, called FLORIA, whose uim is t o provide a virtiial t i m e environment f o r , application proyr'ums (distributed discrete eveiit simulation is the most krwwn of the applications based on such a virid t ime the so called s i m u l a t i o n t i m e and consequently constatutes the paradigm of this class). This paper presents first basic feutures of the virtual t i m e concept and then describes the time-related aspects of the amplementataon of a distributed kernel dedicuted to virtual t ime driven applications.
