Since the batch compute nodes do not allow to use ssh/scp (which is required by '''mrun''' for carrying out several crucial tasks, e.g. for automatic submission of restart runs), the ssh/scp commands are executed on one of the login nodes (blogin1) as a workaround. Therefore, blogin1 must be a known host for ssh/scp. This requires the user to carry out the following three steps just once:30 Starting from r1255, PALM allows full remote access of the Berlin complex of HLRN-III.

After closing the '''allinea''' session, don't forget to leave the interactive job with "{{{exit}}}" command. If you did not use the entire requested {{{walltime}}} for debugging, you should cancel your interactive session on the computing nodes by the "{{{canceljob}}}"-command. 149 149 150 The HLRN III provides a brief online documentation for '''alinea''' (see https://www.hlrn.de/home/view/System3/AllineaDDT for details).150 The HLRN-III provides a brief online documentation for '''alinea''' (see https://www.hlrn.de/home/view/System3/AllineaDDT for details).
