<div dir="ltr">Dear all Wien2k users,<br>It is a pleasure to report that at last my problem is solved. <br>Here, I would like to express my gratitude to Peter Blaha, Laurence Marks, Gavin Abo and Fecher Gerhard for all their very nice and valuable comments and helpful links.<br>Sincerely yours,<br>Leila<br><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 29, 2021 at 7:07 PM Peter Blaha <<a href="mailto:pblaha@theochem.tuwien.ac.at">pblaha@theochem.tuwien.ac.at</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">The difference beteen lapw0para and lapw1para is that<br>
lapw0para always executes mpirun on the original node, lapw1para maybe not.<br>
<br>
The behavior of lapw1para depends on MPI_REMOTE (set in <br>
WIEN2k_parallel_options in w2k21.1 (or parallel_options earlier).<br>
With MPI_REMOTE=1 it will first issue a ssh nodename and there it does <br>
the mpirun. This does not work with your settings (probably because you <br>
do not load the modules in your .bashrc (or .cshrc), but only in your <br>
slurm-job and your system does not transfer the environment with ssh.<br>
<br>
The recommended option for mpi version 2 (all modern mpis) is to set <br>
MPI_REMOTE to zero. The mpirun command will be issued on the original <br>
node, but the lapw1_mpi executables will run as given in .machines.<br>
<br>
This should solve your problem.<br>
