Allocation of vertices to processes prior to partitioning
Hello,
I have two questions related to the distribution of vertices among processes prior to calling a partitioning function.
- When using ParMETIS V3 AdaptiveRepart (), is there a performance difference between the Coupled and the Uncoupled configuration? How much?
- Let's say I'm assigning all vertices to Process 0 when using ParMETIS V3 PartKway (). Is it going to perform like the serial METIS, or is there still a benefit to using several processes?
Thank you,
Louis
