Network-based highperformancecomputing is gaining increasing popularity among parallel computing community Current parallel environments such as MPI (Message Passing Interface) or BSP (Bulk Synchronous Parallel) can not apply readily to heterogeneous computing platform. In order to exploit the maximum performance potential that a heterogeneous environment brings, we have made some experiments on implementing parallel libraries in pure Java, a fully platform-independent language. the paper describes our experiences in implementation of MPI and BSP in pure Java. implementation and efficiency issues such as data transport, network communication, support thread, barrier synchronization and dynamic class loading mechanism are discussed in detail.
this paper uses fault injection to compare the ability of two fault-tolerant software architectures to protect an application from faults. these two architectures are Voltan, which uses process duplication, and Chamel...

Networks of workstations have become a popular architecture for distributed simulation due to their high availability as opposed to specialized multiprocessor computers. Networks of workstations are also a well-suited framework for distributed simulation systems based on the high Level architecture (HLA). However, using workstations in a distributed simulation system may eventually effect the availability of computing resources for the users who need their computers as working tools. thus, for coarse grained distributed simulation it may be desirable to let the users control to what extent their workstations should participate in a distributed simulation. In this paper, we present a resource sharing system (RSS) that provides a client user interface on each potentially participating workstation. Withthe RSS clients, users of workstations can control the availability of their computer for the HLA simulation federation. An RSS manager keeps track of available computing resources and balances the participating HLA federates among the available workstations.
the concept of mediation has been successfully applied to the development of distributed information systems, where mediators form the middle tier between client applications and data resources, providing valuable abs...
