George MozdzynskiConsultant, European Centre for Medium-Range Weather Forecasts
George Mozdzynski has extensive professional experience of different aspects of supercomputing. He received a Bsc (Hons) degree in Computer Science from Imperial College, London, in 1976. From 1976 to 1985, he worked for Control Data Corporation in the areas of pre-sales, post-sales and benchmarking, working on many scalar (CDC CYBER series systems running NOS/BE and then NOS/VE) and vector systems (CYBER205). One of his early roles at CDC was as part of a team that wrote a CRAY station s/w that provided job and file transfer capabilities between a CRAY1 and a CYBER 175 front-end, the first end-user being ECMWF (who he now works for). From 1986 to 1989 he worked at ETA Systems (ETA10) and from 1989-1994 for Kendall Square Research (KSR1, KSR2) with its innovative AllCache architecture, covering pre-sales and benchmarking activities. He joined ECMWF in 1994, and since then has worked as part of a team on many technical developments to ECMWF's IFS weather forecast model. This included the first distributed memory MPI implementation of IFS, the current hybrid MPI/OpenMP implementation, the EQ_REGIONS partitioning scheme and the radiation interface. Since 2011 he has been working as part of the ECMWF team on the EU funded CRESTA project with specific interest in the use of PGAS techniques.
