static load balancing, ElmerGrid?

Post by josefin »

Hi,

I'm partitioning a mesh (called coarse2) for a parallell run. Using

ElmerGrid 2 2 coarse2 -metis 5 2

i end up with a mesh with 5 partitions with approximately the same number of nodes in each partition. Is there an easy way to add weights (expressing the work load) to the nodes, so that each partition don't have the same number of nodes, but rather the same load?

I think I can do this using standalone metis, but is there an easier way to do it within Elmer?

Cheers,

Josefin

Hi Josefin

Sorry, currently no such option exists.

As a long-term plan we are thinking of including some partitioning features within ElmerSolver. Then the solver would be able to interpret the command file to better deal with load balancing. So I don't think that this load balancing will be addressed within ElmerGrid.
