  Grand Challenge problem - Wikipedia, the free encyclopedia
A Grand Challenge Problem is a general category of unsolved problems.
The definition of a Grand Challenge problem has a certain degree of inherent subjectivity surrounding what is, or is not, a Grand Challenge.
The problem is demonstrably hard to solve, requiring several orders-of-magnitude improvement in the capability required to solve it.

As might be expected, the challenges reflect a variety of concerns, from fundamental questions of broad significance to highly-specific (but important) applied queries, from requests for models and analytic techniques to pleas for help in making certain theoretical concepts or algorithms more ``practical,'' from highly-speculative new proposals to long-standing open problems.

 Adaptive Parallel Computation of a Grand-Challenge Problem: Prediction of the Path of a Solar-Coronal Mass Ejection
For problems with disparate spatial and temporal scales such as these, the use of AMR is extremely beneficial and is almost a virtual necessity -- simple structured grids would grossly under-resolve much of the problem, while over-resolving relatively uninteresting regions.
In the first, timings are shown for a problem that has a fixed size per processor; in the second, timings are shown for a problem that has a fixed total size.
As expected, the fixed size problem is somewhat less scalable, since as it is distributed across more and more processors the ratio of communications overhead to computing cost rises.
