Large-scale HPC simulations with their inherent I/O bottleneck have made in situ an essential approach for data analysis. The workshop "In Situ Visualization: Introduction and Applications" provides a venue for speakers to share practical expertise and experience with in situ visualization approaches. We encourage contributed talks on methods and workflows that have been applied in this scenario.

For this 3rd edition of the workshop, we additionally encourage submissions on approaches that either did not work at all or did not live up to their expectations. We therefore expect to get first-hand reports on lessons learned. Speakers should detail if and how the application drove abstractions or other kinds of data reductions and how these interacted with the expressiveness and flexibility of the visualization for exploratory analysis or why the approach failed.

Our goal is to appeal to a wide-ranging audience of visualization scientists, computational scientists, and simulation developers, who have to collaborate in order to develop, deploy, and maintain in situ visualization approaches on HPC infrastructures. We hope to provide practical take-away techniques and insights that serve as inspiration for attendees to implement or refine in their own HPC environments and to avoid pitfalls.

Submission Guidelines

We accept submissions of papers with at most 12 pages (excluding references) in Springer single column LNCS style, see LaTeX and Word templates at

    http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0

The review process is single or double blind, we leave it to the discretion of the authors whether they want to disclose their identity in their submissions. Submissions are exclusively handled via EasyChair:

    https://easychair.org/conferences/?conf=woiv18

All submissions will undergo a peer-review process by experts in the field, and will be evaluated according to relevance to the workshop theme, technical soundness, thoroughness of success/failure comparison, and impactfulness of method/results.

List of Topics

Areas of interest for WOIV include, but are not limited to:

In situ infrastructures

• Current Systems: production quality, research prototypes
• Successful and unsuccessful approaches, dead ends
• Opportunities / Gaps

System resources, hardware, and emerging architectures

• Enabling Hardware
• Hardware and architectures that provide opportunities for in situ processing, such as burst buffers, staging computations on I/O nodes, sharing cores within a node for both simulation and in situ processing

Methods/algorithms/applications/Case studies

• Best practices
• Analysis: feature detection, statistical methods, temporal methods, geometric methods
• Visualization: information visualization, scientific visualization, time-varying methods
• Data reduction / compression
• Examples/case studies of solving a specific science challenge with in situ methods / infrastructure.

Simulation

• Integration: data modeling, software-engineering
• Resilience: error detection, fault recovery
• Workflows for supporting complex in situ processing pipelines

Requirements

• Preserve important elements
• Significantly reduce the data size
• Flexibility for post-processing exploration

Program and Organizing committee

• Kenneth Moreland, Sandia National Laboratories
• Guido Reina, University of Stuttgart
• Thomas Theussl, King Abdullah University of Science and Technology
• Tom Vierjahn, RWTH Aachen University

Publication

At least one author of each paper must be registered for the workshop and present their work in order for the paper to be published in the proceedings. The proceedings will appear as post-conference workshop proceedings to give authors the flexibility to adjust their contributions based on the feedback given during the workshop. Preliminary (conference-ready) versions will be collected and made available to workshop participants during ISC.

Venue
