Dear Elham, with all due respect, do you know what are you trying to calculate? Does you PhD advisor know how to do it? if not, I suggest you change topic. Anyway, there exist several thousands of papers on thermoelectric properties (typically of Heusler compounds). The majority of them plot

Dear Antonio Before struggling with parallelization setup, I see that Estimated total dynamical RAM >    1900.41 GB your calculation requires more or less up to 2TB RAM. I can't see your setup (e.g., the supercell containing your cluster) but I suggest that you ask yourself if there

Dear all, I have a silicon nanocluster with 1000 atoms with 1 1 1 k-mesh (only Gamma point). I cannot manage to run the calculation due to memory issue. I use a computational cluster with 128 core/node and 200 GB RAM per node. I am using PWSCF v.7.3. In the input I set ecutwfc= 29 and cg
