Dear All,
do you have any experience with the new multiLevel docomposition (core/node)? How much does it accelerate? Do you know some reference, validation, testing? Have a nice day, Typhoon |

Greetings Typhoon,
The closest thing I've seen here in the forum is the n-halo decomposition: http://www.cfd-online.com/Forums/ope...alo-layer.html - so you might want to ask thibault_pringuey directly what results he got. The other closest thing I know of is the work that is either being done or has already been done in the variant OpenFOAM 1.6-ext, where multi-threading capabilities have been (or tried to) added. I've never used it like that, so I don't have a clue if it's better or not. The other thing you might want to look for is OpenFOAM with "OpenMP" (not OpenMPI), but I haven't seen anything about yet. Best regards, Bruno

Did you ever figure out how to do multi level decomposition and what the speed up is?
