[petsc-users] Installation on NEC SX-Aurora TSUBASA

[Rafael Monteiro da Silva]

Thank you Satish and Stefano for pointing me out how to do this.

Stefano, if I'm interpreting correctly, I could try to add build options I
need to this script. Is that correct?

First, I'll try to install (based on arch-necve.py script) and then, as
Satish suggested, include additional build options.


Rafael.
