I am in the Atmospheric Science group at the University of Manchester (formerly a UMIST department) working on modelling aerosol over the UK to help determine its effects on regional health and climate, and to help key stakeholders take informed decisions.
I previously worked in the Dept. of Computer Science at the Univ. of Manchester, UK, where my field of expertize was high performance computing. I was key researcher for the softIAM project between Centre for Novel Computing and the Tyndall Centre developing a community integrated assessment model (cIAM) for climate research and have also worked for the CCSR on data sensitivity and the Mobile Systems Architecture (MSA) group on wireless network simulations.
Previous work included helping the Southampton Oceanographic Centre with optimization of their ocean modelling code, occam and developing Ovaltine, an application for determining the overheads of an OpenMP code with respect to a sequential version of the same code.
I continue to be interested in the performance analysis of Fortran programs, particularly on SGI HPC machines and have brought together some of what I've learned so far.
At the end of the last century, I prepared and ran several courses relating to the SGI Origin2000 including: OpenMP, and a 3 day Optimisation and Parallelisation course. I've also spent lots of time working with SGI on (potential) bugs to compilers and implementations of OpenMP. I was CSAR's OpenMP expert, as well as supporting users on both their Origin2000s (kilburn.mcc.ac.uk, fermat.cfs.ac.uk) and the Cray T3E-1200E (turing.cfs.ac.uk) [NB: most, if not all, of these machines have now been replaced by upgrades], and worked with others to maintain several web sites including:
I've also attended the following conferences and workshops:
I have refereed papers for EuroPar 2001, EuroPar 2002, EuropeanAcrossGrids, compFrame2003 and SuperComputing 2003.
