<div dir="auto">Gavin has already answered in large part, but let me add a little.

I have been told that there are "security issues" with various commands that are remotely executed or batch commands. You will need to find out how to export the relevant environment so lapw0 etc know. At the moment, even though you are setting up everything on your head node, the lapw0_mpi running remotely does not have this information.</div><div dir="auto"><br></div><div dir="auto">N.B., sometimes you can change the linking options and use static compilation, which avoids many or all of the issues in 2).<br><br><div data-smartmail="gmail_signature" dir="auto">_____<br>Professor Laurence Marks<br>"Research is to see what everybody else has seen, and to think what nobody else has thought", Albert Szent-Gyorgi<br><a href="http://www.numis.northwestern.edu">www.numis.northwestern.edu</a></div></div></div><br><div class="gmail_quote"><div dir="ltr">On Fri, Jun 15, 2018, 4:03 AM venkatesh chandragiri <<a href="mailto:venkyphysicsiitm@gmail.com">venkyphysicsiitm@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Dear Prof. Laurence Marks,</div>

</div>
<div>thanks for your reply. As pointed in my mail I kept all the variable paths to bashrc file as well as in the jobscript file. Also I did the "ldd lapw1c_mpi"</div>

<div>As I highlighted above <strong>libmpifort.so.</strong>12 has well defined path. do you have any comment on this.</div>
<div><br>
</div>
<div><br>
</div>
<div>Further, you are pointed out that "the shared libraries are not present on the computer you are connecting to via ssh and/or the path has not been exported ". I already copied the key in the<br>
id_rsa.pub file to authorized_keys file (both are in the same server where wien2k installed) to make the password free ssh.</div>

do I need to change the permission between the authorized_keys & id_rsa.pub ...?</div>
