= ''HPC-06_SimonM-extendedhaloes'' Last edition: '''[[Wikinfo(changed_ts)]]''' by '''[[Wikinfo(changed_by)]]''' The PI is responsible to closely follow the progress of the action, and especially to contact NEMO project manager if the delay on preview (or review) are longer than the 2 weeks expected. [[PageOutline(2, , inline)]] == Summary This work builds on the elimination of ghost rows and columns and the tidying of libmpp.F90 carried out in 2017 to introduce arbitrary width haloes and thereby reduce the necessary frequency of boundary exchanges. This was an un-started task from the 2018WP (formerly 2018WP/HPC-05_AndrewC-extendedhaloes, ''#2021'') which has been carried over.
