Mobile 3D Visualization Presentation Thursday July 19. Pat Marion and Utkarsh Ayachit will present as part of the OSCON Mobile Track.

The Visualization Toolkit and ParaView are two widely used open-source, visualization and data processing tools for scientific computing. They are designed to be used on a variety of data forms, ranging from medical to computational meshes to unstructured data such as documents. ParaView in particular is used by many High Performance Computing centers such as the U.S. National Labs, NSF HPC resource centers such as the San Diego Supercomputing Center, and internationally such as at the new Ter@Tec French commercial/government HPC consortium. One of their major claims to fame is these tools can process huge amounts of data, demonstrated on petabyte datasets, and on hundreds of thousands of computing cores, for example 160,000 cores on Argonne’s Blue Gene supercomputer.

Recently there has been community demand to use VTK and ParaView systems on mobile platforms. Consequently we have developed two new tools to address this demand. VES is the VTK OpenGL ES rendering subsystem that runs on iOS and Android platforms. It has been used to build the simple application KiwiViewer (available in App stores) to demonstrate it use in a simple viewing application. ParaViewWeb is a remote web interface for 3D visualization with ParaView as a server, which can support a variety of clients including collaborating sessions. Moreover, ParaViewWeb also provides a JavaScript API based on the ParaView scripting features and capabilities. Thus with these two tools, VES and ParaViewWeb, it is possbile to use the powerful visualization systems VTK and ParaView on mobile platforms or to view and interact with huge data.

In this presentation, the two principal developers of VES and ParaViewWeb (Pat Marion and Utkarsh Ayachit, respectively) will describe the architecture, API, and usage of these systems, and provide real-time demonstrations, including client interface to a computing cluster. They will demonstrate the power of these tools through examples such as brain atlas on a phone, and interactive streamline generation and visualization on a tablet.

OSEHRA – Building an Open Source EHR for All PresentationThursday July 19, 4:10pm. Luis Ibanez and Rick Avila, with Seong Ki Mun of OSEHRA, will present as part of the OSCON Healthcare track.

In 2011, one of the most remarkable events in the history of Open Source and Healthcare took place. The Department of Veterans Affairs (VA), after several years of planning and consideration, made concrete and decisive steps toward creating an Open Source EHR based on the Veterans Health Information Systems and Technology Architecture (VistA).

VistA is a rich, automated environment that supports day-to-day operations at local Department of Veterans Affairs (VA) health care facilities. It is considered to be the most effective EHR system deployment in the world. It has demonstrated to be an effective tool on increasing the quality of healthcare delivery while at the same time reducing its cost. Up to now, VistA has been available to the public outside of the VA through releases made in response to Freedom of Information Act requests.

In July 2011, the VA tasked OSEHRA, a non-profit organization, with the creation of an open source environment in which VistA could transition to become an Open Source EHR that can take advantage of the agility, innovation and high quality that are characteristic of open source projects. Since then, OSEHRA has been working in a very pressing schedule to deploy the software development tools and community coordination resources that are required to positively engage the larger open source community along with the many VA expert developers into a cohesive effort to build an Open Source EHR.

If you are enthusiastic about the future of Open Source EHR systems, please join us in this session, to explore together how we can collaborate on one of the most significant projects of this decade.
