I cannot log onto the cluster. I got this error:
The reason this message appreas is that the host's ssh key has been changed due to the OS upgrade. The simple fix to this is to go into your '.ssh' directory, and open the file 'known_hosts' (or known_hosts2, whichever one the error message specifies) in your favorite editor. Find the line that starts with the host that you were connecting to and delete the line. You will get a message like the one that you saw when you connected to a server for the first time.My job script says matlab cannot be found. What happened?
We have changed the way how matlab will be maintained. In order to set matlab path automatically when you log in, add the following line to your .bashrc (for bash) or .cshrc (for csh, tcsh) depending on your shell.setpkgs -a matlab
My job script ran fine on the old cluster. However, I saw random errors when running the
same script on the new cluster. Some runs give no output at all, while others indicate "segmentation faults". How to resolve
this?
If you have set up your own environmental variables in your .cshrc/.tcshrc, you will need to add proper entries to your .bash_profile or .bashrc after you change your shell to bash. e.g., if you have
alias rm '/bin/rm -i'in your .cshrc, you should add:
alias rm='/bin/rm -i' in your .bashrc or .bash_profile file. Or if you have:
set path = (/bin /usr/bin /sbin $HOME/bin)in your .cshrc, you should add:
export PATH=$PATH:/bin:/usr/bin:/sbin:$HOME/bin in your .bashrc or .bash_profile file etc.
