SU2 High Memory Footprint-CGNS Reader
 

Guys,

I'm observing a very high memory footprint/processor basis on running SU2_CFD.

nElements: 85Million
nNodes: 20 Million
Case: NASA CRM Model (CGNS MESH)

nProcs: 24

memory per process ~ 10GB

Looks like the CGNS reader reads the entire mesh onto all Partitions ? Also I can not use more than 32 processors for this mesh size. It exits while it is reading a particular section.

Any comments ?

Cheers,
Dominic
