Accurate and Efficient Solution Techniques
Error Control & Dynamic Mesh Adaptation
Parallel HPC
- Technological advances facilitate research requiring very large scale computations
- High computing power is needed in many FE/FVM simulations (fluid flow & transport in porous media, heat & mass transfer, elasticity, etc.)
- Higher demand for simulation accuracy
- Higher demand for computing power
- Higher demand for simulation accuracy
- To meet the demand for high computational power:
- The use of sequential machines is often insufficient (physical limitations of both system memory and computer processing speed)
- Use parallel machines
- Develop better algorithims
- Accuracy and reliability of the computational method
- Efficient use of the available computing resources
- Closely related to:
- Error control and adaptive mesh refinement
- Optimization
- The use of sequential machines is often insufficient (physical limitations of both system memory and computer processing speed)
Scientific Visualization
- Importance
- Integration of ParaGrid with visualization (not compiled together):
- Save mesh and solution in files for later visualization
- Exchange data through sockets for real-time visualization
- GLVis
- Portable, based on OpenGL (compiled also with Mesa)
- Visualize simple geometric primitives (vertices, lines and polygons)
- Can be used as a "server"
- Waits for data to be visualized
- Uses fork after every data set received
- Combines parallel input (from ParaGrid) into a sequential visualization
- VTK based
- Added to support volume visualization
