Particle-Mesh-Methods on Next Generation Supercomputers

In the coming years supercomputers will have millions of compute cores.
It is estimated that the computing power will grow by a factor of 1000 in the coming years while the memory will only grow by a factor of 10.
This means that at optimum codes can be 100 times faster than before.
I will show that such codes exist today and both allow and require online visualization and interaction with the user.
Based on the example of particle-mesh methods I will present the most important techniques on how to write optimum codes.
