[Pw_forum] PB with electron-phonon coupling in parallel program

[jeremie]

Dear all

 

I am running the parallel version of PWscf 3.1.1 for electron phonon
calculation on a Linux cluster. This calculation based on the example 7 runs
perfectly in the serial mode (or with parallel executable but on one node)
but I have a problem when I run the calculation on more than one node. The
first q point works fine but for the following I get the error message when
calculating the EP coupling:
