Experts agree that the exascale machine will comprise processors that contain many cores, which in turn will necessitate a much higher degree of concurrency. Software will require a minimum of a 1,000 times more concurrency. Most parallel analysis and visualization algorithms today work by partitioning data and running mostly serial algorithms concurrently on each data partition. Although this approach...
Nomena at a stunning degree of precision and sophistication. But it is more and more impractical to store the data to disk in real time because of the scale of the output data, and thus the conventional post-processing based technique no longer applies. In response to this challenge, we design and implement an in-situ visualization system based on MPI and CUDA. In this system, the simulation code...
