本文提出了一个结合的国家的实践提取为基础的原位分析，原位分析的治疗作为一种形式的I/O，并建议社会就处理原位和I/O库。提取原位分析使用某些技术（例如，等值面化）并且仅保存提取的信息。结果发现，这种方法虽然减少了输出，但仍然会造成并行I/O问题。最初的解决方案是修改ParaView Catalyst输出以使用ADIOS，尽管这只带来了微小的改进。进一步的聚合，即使是大规模的提取I/O，也是解决这个问题的主要关键。最后，本文提出了一个单一的库可以提供I/O，原位分析，代码耦合，和弹性的能力，因为重叠的步骤，必要的引导每个位置。
This paper presents a combination of state-of-the-practice for extraction-based in situ analysis, the treatment of in situ analysis as a form of I/O, and a proposal to the community regarding the handling of in situ and I/O libraries. Extraction in situ analysis extracts subsets of data using certain techniques (e.g., isosurfacing) and saves only the extracted information. It was found that this approach, while reducing output, still poses parallel I/O issues. An initial solution was to rework ParaView Catalyst output to use ADIOS, though that only brought about minor improvements. Further aggregation, even for large-scale extraction I/O, was the primary key to solving that issue. Finally, the paper presents the position that a single library could provide I/O, in situ analysis, code coupling, and resiliency capabilities because of the overlap in steps necessary to bootstrap each.
