In this chapter, we look at technology changes affecting scientists who run data-intensive simulations, particularly concerning the ways in which these computations are run and how the data they produce is analyzed. As computer systems and technology evolve, and as usage policy of supercomputers often permits very long runs, simulations are starting to run for over 24 hours and produce unprecedented amounts of data. Previously, data produced by supercomputer applications was simply stored as files for subsequent analysis, sometimes days or weeks later. However, as the amount of the data becomes very large and/or the rates at which data is produced or consumed by supercomputers become very high, this approach no longer works, and high-throughput data movement techniques are needed.
