Live, Interactive, In-Situ Visualization of Large-Scale Plasma Simulations

In large-scale scientific simulations, I/O has become a bottleneck that can slow down the exploration of unknown physical scenarios. We show that it is vital to view a HPC system not only in its ability to simulate the system but also to visualize the simulated data. By keeping the data of the simulation in the GPU memory, remote analysis via a Wi-Fi connection can work at frame rates well above 10 fps while latencies are not of importance, even when spanning continents. This presentation includes a live demo.
