If you have not done so, please submit a ticket about this issue. That&#039;s the best way to get it resolved.<br /><br />Regards<br />Yaakoub

Octave seems to work fine on the compute nodes. Did you submit a ticket about this issue sir? Did you get it resolved? <br /><br /><div class="quote-title">Jingjing Li:</div><div class="quote"><div class="quote-content">For anyone who is interested: Octave on Lonestar is configured for login nodes only. We can not run on working nodes yet. They say they are working on installing octave on the working nodes.<br /><br />BTW, since we are supposed not to run jobs on login nodes, basically this means Octave on lonestar is very much useless, I assume.</div></div>

I can recommend the use of an ssh-agent, it helps tremendously. Also for large file transfers I will also recommend globus online.<br /><br />A quick google search for ssh-agent how to:<br />http://superuser.com/questions/8077/how-do-i-set-up-ssh-so-i-dont-have-to-type-my-password<br /><br />And globus online:<br />https://www.globusonline.org/<br /><br /><br />Regards<br />Yaakoub

Regarding the script: watch out. You are setting an empty pass phrase on line 26.<br /><br /># create ssh key and add to config file<br />if [ ! -e ~/.ssh/${SERVER} ]; then<br /> ssh-keygen -q -t rsa -N &#034;&#034; -f ~/.ssh/${SERVER}<br /><br />This is great way to make compromising your account very easy. <br /><br />Regards<br />Yaakoub

I strongly suggest you copy your key to authorized_keys2 instead of authorized_keys to avoid any mpi_spawn errors. Standard security precautions apply: use a strong password for your key, keep it somewhere safe, make sure permissions are locked down etc... <br /><br />Regards<br />Yaakoub
