ISAV 2016: In Situ Infrastructures for Enabling Extreme-scale Analysis and Visualization

Held in conjunction with
SC16: The International Conference on High Performance Computing, Networking, Storage, and Analysis.

Sunday 13 November 2016 (full day)

Salt Palace Convention Center, 251-A

Workshop Theme

The considerable interest in the HPC community regarding in situ analysis and visualization is due to several factors. First is an I/O cost savings, where data is analyzed/visualized while being generated, without first storing to a file system. Second is the potential for increased accuracy, where fine temporal sampling of transient analysis might expose some complex behavior missed in coarse temporal sampling. Third is the ability to use all available resources, CPUs and accelerators, in the computation of analysis products.

The workshop brings together researchers, developers and practitioners from industry, academia, and government laboratories developing, applying, and deploying in situ methods in extremescale, high performance computing. The goal is to present research findings, lessons learned, and insights related to developing and applying in situ methods and infrastructure across a range of science and engineering applications in HPC environments; to discuss topics like opportunities presented by new architectures, existing infrastructure needs, requirements, and gaps, and experiences to foster and enable in situ analysis and visualization; to serve as a "center of gravity" for researchers, practitioners, and users/consumers of in situ methods and infrastructure in the HPC space.

Participation/Call for Papers

We invite two types of submissions to ISAV 2016: (1) short, 4-page papers that present research results, that identify opportunities or challenges, and that present case studies/best practices for in situ methods/infrastructure in the areas of data management, analysis and visualization; (2) lightning presentation submission, consisting of a 1- or 2-page submission, for a brief oral presentation at the workshop. Short papers will appear in the workshop proceedings and will be invited to give an oral presentation of 15 to 20 minutes; lightning round submissions will not be included as part of the proceedings. Submissions of both types are welcome that fall within one or more areas of interest, as follows:

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

In situ infrastructures: Current Systems: production quality, research prototypes; 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 postprocessing exploration

Review Process

All submissions will undergo a peer-review process consisting of three reviews by experts in the field, and evaluated according to relevance to the workshop theme, technical soundness, creativity, originality, and impactfulness of method/results. Lightning round submissions will be evaluated primarily for relevance to the workshop.

Publication in proceedings, presentation at the workshop.

All paper submissions that receive favorable reviews will be included as part of the workshop proceedings, which will be published along with other SC16 workshop proceedings in the ACM Digital Library and IEEE Xplore. Lightning round submissions will not be included as part of the proceedings. Subject to the constraints of workshop length, some subset of the accepted publications will be invited to give a brief oral presentation at the workshop. The exact number of such presentations and their length will be determined after the review process has been completed.

Submission Process

Authors are invited to submit papers of at most 4 pages in PDF format, excluding references, and lightning presentations of at most 2 pages in PDF format, excluding references. Papers should be formatted in the ACM Proceedings Style (templates available at and submitted via EasyChair ( No changes to the margins, spacing, or font sizes as specified by the style file are allowed.

Papers must be self-contained and provide the technical substance required for the program committee to evaluate their contributions. Submitted papers must be original work that has not appeared in and is not under consideration for another conference or a journal. See the ACM Prior Publication Policy for more details. Papers can be submitted at
