Hi,
I am attempting to do analysis on a mesh with 8M cells. The mesh was
created with gridgen, and am using the ExodusII IO class to read the
mesh. I am using the ParallelMesh class with the library configured with
Parmetis (and also with Metis, but I am not sure if this would matter).
The process increases the memory requirement to ~22GB irrespective of
number of processors, and I am wondering if the process of reading the mesh
and then partitioning is making each process read the entire mesh before
breaking it up.
If so, is there a flag/setup that I am missing to enable reading the
mesh in pieces?
Thanks,
Manav
