Dear Iurii, Thank you for your clear and detailed explanation. I have launched the calculations as you suggested and they are running fine.

Dear Vahid, The HP calculation can be split and parallelized. It depends how you want to do this. In example 7 of HP one needs to perturb two atoms, one Mn atom and one Ni atom. So we can split the HP calculation into two - in this case, we need to have different "outdir" for these two independent calculations, say TMP1 and TMP2. You would need to run the PW calculations once (e.g. using TMP1) and then copy temporary files from TMP1 to TMP2. Then you run HP by perturbing Mn and using TMP1, and run HP by perturbing Ni and using TMP2. Once the calculation is finished successfully, you need to copy the output of TMP2/HP to TMP1/HP and then run the final step with compute_hp = .true. and using TMP1. On top of that, you can parallelize each calculation over q points using start_q, last_q, and sum_pertq. In this case, you would need to further split TMP1 into subfolders and TMP2 into subfolders, if you want to run this in parallel (if you run it sequentially, then no need to split TMP1 and TMP2 subfolders). I hope this clarifies a bit how to do it.
