ABSTRACT:

Due to the widening gap between the FLOP and I/O capacity of HPC platforms, it is increasingly impractical for computer simulations to save full-resolution computations to disk for subsequent analysis. "In situ" methods offer hope for managing this increasingly acute problem by performing as much analysis, visualization, and related processing while data is still resident in memory. While in situ methods are not new, they are presently the subject of much active R&D, though as yet are not widespread in deployment or use.

This panel examines different aspects of in situ methods, with an eye towards increasing awareness of the current state of this technology, how it is used in practice, and challenges facing widespread deployment and use. The panel will also explore the issue of whether in situ methods are really needed or useful in the first place, and invites discussion and viewpoints from the SC community.
