Grid indexing / local cell re-ordering for cache reuse

Post by marcimb » Mon May 03, 2021 10:02 am


after browsing through some of the older MPAS presentation slides in ... _leeds.pdf, I found a slide about local cell re-ordering (slide 10) which has the potential to improve cache reuse. While it is mentioned in the presentation that there is no local cell re-ordering performed for MPAS meshes, the graph to the right suggest that there is a possible way of obtaining this kind of local cell re-ordering. Have there been further developments in this direction and are there any plans to include such a local cell re-ordering in the official MPAS workflow?

Best regards,
