Highlights

Below is a selected list of highlights generated for VTK-m related R&D.

In Situ Vector Field Reduction Using Lagrangian Basis Flows
Lagrangian Basis Flows are an alternate representation of flow fields that record displacement rather than velocity. VTK-m is used to compute Lagrangian Basis Flows in situ with simulation to reduce I/O demands and improve post hoc analysis accuracy.

In Situ Visualization in WDMApp Using VTK-m
Integrating VTK-m with simulations for the planned experimental ITER fusion reactor. Images are generated in situ while the simulation is running.

WDMApp

Flow Visualization in WarpX Laser Wakefield Simulations
Unlike for a typical fluid velocity field, particle trajectories for relativistic plasma and accelerator physics must be inferred from electromagnetic fields as well as the particles’ momentum. VTK-m’s particle tracing was customize for the specifics of WarpX particle trajectories.

WarpXFlow

In Situ/In Transit Visualization with WarpX
VTK-m was used to perform in situ visualization and rendering during a simulation of a 10-stage laser-wakefield accelerator. The simulation was run on 600 GPUs on Summit at OLCF. This visualization was featured during the keynote talk of ISAV 2020.

WarpXInSitu

Large-Scale In Situ Visualization of Raleigh-Taylor Instability with Ascent and VTK-m
Coupled to a simulation through Ascent, VTK-m visualized a 97.8 billion element Raleigh-Taylor instability simulation on 4096 nodes of the Sierra computer at Lawrence Livermore National Laboratory.

Raleigh-Talylor

Scientific Discovery via Visualization Using Accelerated Computing
A short retrospective and timeline of the origins of VTK-m.

History

Enabling in situ visualization of petascale time-dependent CFD simulations
Coupled to a PyFR CFD simulation through ParaView/Catalyst, VTK-m was used to visualize flow over a low pressure turbine linear cascade. The simulation was done in situ with the simulation with the data remaining entirely on the GPU for maximum efficiency and performance.

PyFR

Live Demonstration of In Situ Visualization on Accelerator Processors
A demonstration of live in situ visualization on the Titan supercomputer. PyFR, a CFD simulation that was coupled with ParaView/Catalyst, ran on 256 GPUs of the Titan supercomputer at Oak Ridge National Laboratory, visualized its results with VTK-m, and displayed its results on a live client application running at the SC 2015 show floor.
