Greetings, I have been using Quantum Espresso for performing SCF calculations to compute the band gap and energies of crystal structures. Is there a way to perform DFT simulations on a large number of input crystals parallely using QE, i.e., data parallelism across multiple inputs (in addition to parallel calculations for each crystal)? For instance, what is the most optimal way to run the pw.x command for say 5000+ crystals?
Further, I am aware that there is GPU support for QE. There are issues while trying to install GPU-enabled QE which I am trying to figure out, but I was wondering if it provides reasonable speedup especially when I am dealing with multiple crystals. Also, I've been referring to https://gitlab.com/QEF/q-e-gpu for GPU-enabled QE installation. If there are any other useful resources please let me know. I am using QE as an evaluation scheme for deep learning outputs, so an effective way for GPU-based DFT simulation would be of great help.
