See Decoding Performance: A Scalability Showdown Between CalculiX and Code_Aster
Static example, 4 Million tet10 elements
Advantage calculix with PARDISO to 200.000 nodes per core
Code_aster here only half Performance.
Commercial pardiso is here extreme better with more cores than Intel MKL pardiso.
So commercial users should include pardiso solver to safe computer resources, energy and time.
PaStiX is about 3 to 4 times better than Intel MKL Pardiso. But original Pardiso 8 is mostly more better in their benchmarks with factor 4 to 100 example dependent.
