Build and Execute Environment

Qiang Guan
At exascale, the challenge becomes to develop applications that run at scale and use exascale platforms reliably, efficiently, and flexibly. Workflows become much more complex because they must seamlessly integrate simulation and data analytics. They must include down-sampling, post-processing, feature extraction, and visualization. Power and data transfer limitations require these analysis tasks to be run in-situ or in-transit. We expect successful workflows will comprise multiple linked simulations along with tens of analysis routines. Users will...

Forums are provided for asking questions about the services, profiles, and implemenation issues.

Sci-Vis Framework

PNNL Arthur Bleeker
SVF is a full featured OpenGL 3d framework that allows for rapid creation of complex visualizations. The SVF framework handles much of the lifecycle and complex tasks required for a 3d visualization. Unlike a game framework SVF was designed to use fewer resources, work well in a windowed environment, and only render when necessary. The scene also takes advantage of multiple threads to free up the UI thread as much as possible. Shapes (actors) in...

Stitch v. 1.0 IO Library

Gerald Lofstead & John Mitchell
Stitch is a new IO library focused around supporting simulations where only a small portion of the simulation space changes at each timestep. It improves storage efficiency by only storing the changed data and constructs on request a view of an arbitrary region at a given time by stitching together parts of various outputs. This enables scaling from a single process to 100s of nodes.
