Marta Vallejo: Computational approaches to Uncertainty in Scenario-based models of Climate Change Impacts
My PhD will try to fill the gap between local and global modelling approach by scaling up part of the current ecological models to a global perspective. From this global point of departure, the main focus of the project is the study of how policies, regulations and guidelines can modify the behaviour of the stakeholders involved in the use of landscape and subsequently infering the effects in the physical dynamics of the land cover.
Robert Stewart: Fault Tolerant Symbolic Computation in Exascale Distributed Systems
The past decade has seen distributed computing move into the realms of exascale, heterogeneous networked computer systems. This evolutionary progression has redefined the problems faced for parallel execution on dependable computational systems.
My PhD research is focused on adding fault tolerance at the software level, to satisfy the dependable requirements on such platforms. The ambition is that the outcomes of my PhD will contribute to the HPC-GAP project (High Performance Computational Algebra and Discrete Mathematics), providing a set of fault tolerant mechanisms to overcome hardware failure, byzantine failures, and unreliable heterogeneous topologies. There are a number of target platforms available for developing these mechanisms, including the HECToR cluster in Edinburgh: "The UK National Supercomputing Service", that will ultimately scale up to a million processor cores.
