In this paper, we describe two visualization tools developed on the DAP-510, a SIMD machine having 1024 processors. the two tools are (i) the interactive visualization tool, and (ii) the display tool. the interactive ...

the most time consuming operation in a circuit simulation program is the model evaluation, i.e. the computation of the coefficients for the Jacobian matrix. Since these coefficients only depend on the node voltages an...

distributed real-time control systems increasingly depend on local-area networks (LANs) for information exchange among sensors, processors, and actuators. FDDI (fiber distributed data interface) is a high-speed LAN that can satisfy access delay requirements of such time-constrained applications while simultaneously supporting non-time-constrained applications such as file transfer. the performance of FDDI is examined for time-constrained and non-time-constrained traffic. the simulation results presented include performance parameters such as delay distribution for different classes of messages and the distribution of token rotation times. the effect of errors, such as lost tokens and network severance, on the network performance is examined.
this paper describes the problems involved in instrumenting a distributed system. the design of the MCC ES-Kit instrumentation module is used to illustrate one set of solutions to these problems. Performance measureme...

the parallelization problem can be divided into three main stages: identification of parallelism which includes dependency analysis, partitioning the statements into atomic tasks of granularity suitable to the target ...
