A distributed, parallel implementation of the widely used Modular Semi-Automated Forces ModSAF Distributed Interactive Simulation DIS is presented, with Scalable Parallel Processors SPPs used to simulate more than 50,000 individual vehicles. The single-SPP code is portable and has been used on a variety of diierent SPP architectures for simulations with up(More)
The use of GPUs to accelerate the factoring of large sparse symmetric indefinite matrices shows the potential of yielding important benefits to a large group of widely used applications. This paper examines how a multifrontal sparse solver performs when exploiting both the GPU and its multi-core host. It demonstrates that the GPU can dramatically accelerate(More)
This paper presents the case that education in the 21<sup>st</sup> Century can only measure up to national needs if technologies developed in the simulation community, further enhanced by the power of high performance computing, are harnessed to supplant traditional didactic instruction. The authors cite their professional experiences in simulation, high(More)
This paper addresses the use of emerging technologies to respond to the increasing needs for larger and more sophisticated agent-based simulations of urban areas. The U.S. Joint Forces Command has found it useful to seek out and apply technologies largely developed for academic research in the physical sciences. The use of these techniques in(More)
The Information Sciences Institute and Caltech are enabling USJFCOM and the Institute for Defense Analyses to conduct entity-level simulation experiments using hundreds of distributed computer nodes on Linux Clusters as a vehicle for simulating millions of JSAF entities. Included below is the experience with the design and implementation of the code that(More)
