ISAV 2015: In Situ Infrastructures for Enabling Extreme-scale Analysis and Visualization
Held in conjunction with
SC15: The International
Conference on High Performance Computing, Networking, Storage, and
Monday, 16 November 2015, 2:00 - 5:30p, Hilton Salon D, 500 East 4th Street, Austin, TX
This workshop brings together researchers, developers and practitioners from industry, academia, and government laboratories who use in situ methods in extreme-scale, high performance computing. The goal is to present existing in-situ infrastructures, reference examples in a range of science and engineering applications, 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.
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 filesystem. 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, CPU's and accelerators, in the computation of analysis products.
In situ processing is still a relatively new idea, and up until recently, most implementations have been ad hoc, proof-of-concept prototypes. However, several in situ infrastructure implementations have emerged. ParaView and VisIt both provide tools for in situ analysis and visualization. ParaView Catalyst can be linked to a simulation, allowing the simulation to share data with Catalyst for visualization. Similar capabilities are available within VisIt with the libsim library. Both Catalyst (through Live) and libsim enable the opposite flow of information, sending data from the client to the simulation, enabling the possibility of simulation steering. ADIOS and GLEAN allow simulations to adopt in situ techniques by leveraging their advanced I/O infrastructures that enable co-analysis pipelines rather than changing the simulator. The non-intrusive integration provides resilience to third party library bugs and possible jitter in the simulation.

Participation/Call for Papers
We invite short (4-page) papers that identify opportunities, challenges and case studies/best practices for in situ analysis and visualization. These papers could propose actions, or provide position, or experience reports on in situ analysis and visualization.
Areas of interest for ISAV, include, but are not limited to:
|In situ infrastructures||
|System resources, hardware, and emerging architectures||
Submissions are limited to 4 pages in the ACM format (see here for templates). The 4-page limit includes figures, tables, and appendices, but does not include references, for which you may use up to one additional page. Please submit your paper at the ISAV 2015 EasyChair submission page.
Peer review process
All submissions will undergo a peer-review process consisting of three reviews by experts in the field.
Publication in proceedings, presentation at the workshop
All submissions that receive favorable reviews will be included as part of the workshop proceedings, which will be published along with other SC15 workshop proceedings in the ACM Digital Library and IEEE Xplore.
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.
