Abstract

In order to compare the accelerated implementation with the original software, we observe performance and accuracy. Both sets of simulations are run on the same workstation - an HP Z400 with an Intel Xeon W3505 processor. The GPU used for the accelerated simulations is an Nvidia GeForce 285 with CUDA version 2.3. Table I offers an overview of the performance improvements provided by the accelerated implementation in multiple scenarios and Figures 1-4 show detailed analysis of the performance across a range of complexity metrics for the Cubicle scenario discussed in [2].
