Visualization of flow phenomena in large, time varying data sets demands extensive graphical, computational and memory resources. Recent research in the field of parallel post-processing algorithms and out-of-core data management shows that a good utilization of given resources together with a considerable speed-up may be achieved. One of the main problems is the I/O bottleneck commonly alleviated by data caching and overlapping I/O with computation. Standard prefetching techniques suffice for predictable data demands ...
