Porting and Support for high-resolution climate modelling

Setting up the N512 ORCA 025 job for FEBBRAIO project. Performed scaling analysis, performance optimisaton and general issue resolutions.

Started running N512 ORCA025 job (100 model years) for FEBBRAIO project. The job will complete one model year per day.

Development of script to rebuild NEMO files and manage data (Ongoing).

Cray Reveal performance optimisation

Manuscript entitled "Performance analysis and Optimisation of the Met Unified Model on a Cray XC30" has been submitted for publication in the International Journal of High Performance Computing. http://cms.ncas.ac.uk/attachment/wiki/Projects/Porting/KSivalingam_journal.pdf

Karthee delivered an invited talk at Edinburgh 2015 presenting the performance analysis and data. http://www.easc2015.ed.ac.uk/program-archive/slides/s13aSivilingam.pdf

Karthee also presented at ECMWF. http://www.ecmwf.int/sites/default/files/HPC-WS-Sivalingam.pdf
