Action AGRIF-03_jchanut-TOOLS PI(S) Jérôme Chanut Digest AGRIF nesting tools update. On-line nesting pre-processing tools are outdated and need complete revision to work with the most recent code. We propose in this task: (i) To correct the tool by gathering various fixes done by users, remove obsolete features and test it. (ii) Investigate an alternative, in collaboration with people from the CONFIG MANAGER group. It could be based on the use of the AGRIF library itself, thus making it simpler to navigate through the grid hierarchy.

Action HPC-01_HPCWG_singlecoreperf PI(S) HPC subgroup/Silvia Mocavero & Tim Graham as members of ST Digest The activity is based on the work started in 2017.

A preliminary analysis has been done on Met Office and CMCC systems and memory-bounded routines have been identified. The action will continue during 2018. The following sub-actions are identified: (i) integration of the portable tool in the 4.0 release.
