Parallel Implementation of the phoenix generalized stellar atmosphere program
The Astrophysical Journal, 1997Co-Authors: P H Hauschildt, E BaronAbstract:We describe the Parallel Implementation of our generalized stellar atmosphere and non-LTE (NLTE) radiative transfer computer program PHOENIX. We discuss the Parallel algorithms we have developed for radiative transfer, spectral line opacity, and NLTE opacity and rate calculations. Our Implementation uses a multiple instruction-multiple data design based on a relatively small number of MPI library calls. We report the results of test calculations on a number of different Parallel computers and discuss the results of scalability tests.

ICASSP - Parallel Implementation of the tracking Kalman filter
ICASSP-88. International Conference on Acoustics Speech and Signal Processing, 1Co-Authors: E.k.b. Lee, Simon HaykinAbstract:A Parallel Implementation of the extended Kalman filter (KF) for target tracking systems is presented. The decoupling technique is utilized to reduce computational requirements and to increase Parallelism. Also, the properties of matrices in the tracking KF are exploited to simplify the Implementation complexity. >

Parallel Implementation of a second-order adaptive Volterra filter
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics Speech and Signal Processing, 1991Co-Authors: A. CeliaAbstract:A Parallel algorithm for updating the linear and quadratic coefficients of a second-order Volterra (SVF) filter is proposed. The Parallel algorithm is implemented on both two- and three-node Inmos T-800 transputer arrays. The effective processing bandwidth of the Parallel filter Implementation is compared to that of the traditional serial approach to demonstrate the potential real-time adaptive filtering applications of the Volterra filter. Simulation results for both the Parallel and serial Implementations of the SVF filter are provided to demonstrate the significant performance increase realized by the Parallel Implementation over the serial Implementation. >

research on Parallel Implementation of multi resolution models in distributed interactive simulation
Computer Simulation, 2007Co-Authors: Huang KediAbstract:The Parallel Implementation of multi-resolution models(MRMs)is often encountered in distributed interactive combat simulation.Some key techniques on the Parallel Implementation of multi-resolution models were researched.Two new concepts,named morphism attribute and morphism event were proposed.The problem of consistency maintenance when multi-resolution models were Parallel implemented was researched and a new algorithm was proposed.Then the problem of interaction conflict in MRM was researched.To solve this problem,three methods were given,including mutex locking,conflict detecting and model-oriented method.The affection of morphism interaction to simulation result was analyzed and some basic principles to deal with this problem were given.
