[petsc-users] Petsc performance

[Sang pham van]

Dear everyone,

I want to purchase a high performance workstation which should have from 32
to 64 nodes, price is not so important. The workstation will be used for
cfd simulation purpose.
Would any one help me to chose one? I would very much appreciate  your
suggestions.

Thank you.

Sang
