Dear Jamie,
The problem seems to occur when writing or reading files on a disc. Are you sure that you have enough free disc space? Could you provide please more details about your calculations? Please share your input and output files for all pw.x and hp.x calculations that fail (e.g. using Google Drive).

"HP--A code for the calculation of Hubbard parameters using density-functional perturbation theory." arXiv preprint arXiv:2203.15684 (2022).<https://arxiv.org/pdf/2203.15684.pdf> The hp files run fine when I run them one at a time. However, when I try to parallelize over different perturbed atoms by running them simultaneously as described in section 4.2 I receive errors and at least one run fails. I have tried it on two different computing cluster and they both failed, but with different error messages. I’ve included the input files/errors below. Does anyone know of a way to solve this issue? Input file 1: &inputhp prefix = 'olivine', outdir='outdir/', nq1 = 1, nq2 = 2, nq3 = 3, conv_thr_chi = 1.0d-7, niter_max=250, dist_thr = 5.D-3 perturb_only_atom(5) = .true. / Input file 2: &inputhp prefix = 'olivine', outdir='outdir/', nq1 = 1, nq2 = 2, nq3 = 3, conv_thr_chi = 1.0d-7, niter_max=250, dist_thr = 5.D-3 perturb_only_atom(6) = .true. / Errors from computing cluster 1 Error termination.
