Hi Pietro, Thanks for the message.
> If you want to compute phonons using GPU acceleration, you must use QE-7.2. I am working on recompiling to version 7.2 so I can use this capability. In the meantime, I tried the CPU-only version and I still have the same issue – it just sits at the same point. I was able to run a simple example for silicon on the GPU version without issue. Is it just a speed thing? -Jon
