[Pw_forum] QE_Parallel

[Filippo Spiga]

Dear Gul,

it might help a lot to understand three things:
- where you are running your code (meaning, the hardware platform)
- how you compile the code (meaning how you run configure)
- what libraries and compilers are you using (meaning your environment)

With the little information you provided, there is not much we can do to help.

Cheers,
Filippo
