     24''Investigate NEMO on GPU. This ticket is to document development of NEMO code to be ready to run on GPU. The aproach taken is based on automatic insertion of compiler directives into the pre-proccessed by compiler code with PSYclone. PSYclone works on a target computer so the commits into the branch are the changes in the code to efficiently run code on GPU after directives are inserted.''
