I will have to stick with my PC for a while. I thought that MPI was for running jobs on multiple (actual) machines, but since I can run lapw1 in multiple cores in my Single PC (edit .machine file), I guess I already have MPI installed. </font></div><div class="gmail_default"><font face="georgia, serif"><br></font></div><div class="gmail_default"><font face="georgia, serif">Mr Peter Blaha,</font></div><div class="gmail_default"><font face="georgia, serif">I realize that 300 atoms is quite a lot including magnetic atoms such as Fe and RE elements (4f), in fact, 1 cycle took 5 hours to complete, with 40 min for Lapw0, 1h50min for Lapw1 (on 2 cores) for up and down and 16min for Lapw2 (2 cores) for up and down. </font></div><div class="gmail_default"><font face="georgia, serif">I think the problem is that I am stuck with klist : 2</font></div><div class="gmail_default"><font face="georgia, serif"><br></font></div><div class="gmail_default"><font face="georgia, serif">and if I increase kpoints, so that for example 10 machines would take the job, (klist 10) I think that Lapw0 will take too long since I cannot run it in multiple cores.</font></div><div class="gmail_default"><font face="georgia, serif"><br></font></div><div class="gmail_default"><font face="georgia, serif">About the structure, the unit cell without doping consists of 56 atoms with 16 atoms of Fe (fcc lattice) the doping consists of 0.01 RE + 0.01 Re element doping so that the smallest supercell would be one with 96 Fe atoms. </font></div><div class="gmail_default"><font face="georgia, serif">I will consider your advice and hope that results from doping smaller supercell would help explaining the experimental data we obtained.</font></div><div class="gmail_default"><font face="georgia, serif"><br></font></div><div class="gmail_default"><font face="georgia, serif">Faithfully,</font></div></div><div class="gmail_extra"><br><div class="gmail_quote"><br></div>
