Parallel-in-time integration of Kinematic Dynamos

Understand

The precise mechanisms responsible for the natural dynamos in the Earth and Sun are still not fully understood.

• Numerical simulations of natural dynamos are extremely computationally intensive, and are carried out in parameter regimes many orders of magnitude away from real conditions.
• Parallelization in space is a common strategy to speed up simulations on high performance computers, but eventually hits a scaling limit.
• Additional directions of parallelization are desirable to utilise the high number of processor cores now available.
