    A description is given of a visualization environment that integrates a supercomputer, large storage facilities, and a visualisation server to let scientists analyze large, complex problems and view pseudo-high-performance, interactive graphics on desktop displays. The paper covers the shared, centralized server, the current prototype environment, and the software environment.<> View full abstract»

    An algorithm for solving a large-scale optimization problem concerning decentralized pricing of electrical power has been implemented. To help abstract the communication and layout requirements of the problem away from the main algorithm, a small object system library has been developed. The results are an efficient and easily modifiable solution to the problem and a general approach to solving th... View full abstract»

  • Adaptive message logging for incremental program replay

    Adaptive message logging, which traces dependences between messages and checkpoints and selectively logs messages, letting users accurately and efficiently replay specific portions of parallel programs, is presented. Traces are reduced by logging only messages that cannot be quickly recomputed during replay. By restarting the execution at the right set of checkpoints, many of the messages needed f...

    Although RPC is the current method of choice for distributed interprocess communication, its complexity might increase demand for higher-level approaches. The Virtual Network, an idealized, intelligent software network that hides the underlying physical network's incompatibilities and complexities from the distributed programs that run on it, is presented as a solution. The components of the Virtu... View full abstract»

  • Multiple reservations and the Oklahoma update

    A multiple reservation approach that allows atomic updates of multiple shared variables and simplifies concurrent and nonblocking codes for managing shared data structures such as queues and linked lists is presented. The method can be implemented as an extension to any cache protocol that grants write access to at most one processor at a time. Performance improvement, automatic restart, and livel...

  • Bounded and minimum global snapshots

    A distributed protocol that records bounded snapshots of FIFO and non-FIFO communication channels, thus avoiding the unbounded storage requirements of other global-snapshot protocols, is described. The assumptions and definitions underlying the protocol are discussed, and its correctness is demonstrated. A modified protocol that can minimize a recorded global state by solving the maximum-flow prob... View full abstract»
