Compiler choice

[ramon_garcia]

Hello, I am interested in running cp2k with hybrid density functional
(B3LYP, PBE0). It seems that CP2k supports them, but it is sensitive
to compiler choice. I have read:

Does this mean that I should refuse to use Intel or Portland
compilers? Is the GFortran compiler a valid choice?
