[Q-e-developers] Compiling QE-GPU without openmp

[Pietro Bonfa']

Dear Filippo,

I'm sorry, I saw that there is a misleading information in the
compile.sh file on github.

The error shows up if I use PrgEnv-cray module (module switch
PrgEnv-intel PrgEnv-cray).

I put the output of "ftn --cray-print-opts" and "ftn -craype-verbose"
here: http://pastie.org/10908149

Bests,
Pietro
