[Pw_forum] large system parallel execution problem

[German Samolyuk]

Dear QE users and developers,

I'm trying to optimize structure of super cell containing 433 magnetic Fe  atoms
on Cray xt4 machine.
The program runs electronic structure self consistency and calculate forces
but stops at first structure optimization step.
Do you know possible reason. It works for smaller systems.
I've attached archive with input and output files together with pbatch I used

Thank you
