Abstract
VIPP is an instructional tool for exploring performance tradeoffs that arise when load balancing various particle methods on distributed memory MIMD computers. VIPP enables its user to interactively visualize factors affecting performance including: granularity, geometry, and the relative costs of communication and computation. VIPP employs trace driven, application-level simulations in lieu of low level machine-level behavioral simulations. While such simulations ignore certain performance factors---such as the cache and the processor interconnect---they are ideal for instructional use: they require only a working serial program, and they may be run inexpensively on a low-cost workstation. We present some experiments to illustrate VIPP's capabilities. In addition to use as an instructional tool, VIPP's ability to perform qualitative performance prediction may be helpful in guiding parallel implementations.
