    30 Starting from r1255,  PALM allows full remote access of the Berlin complex of HLRNIII. 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:

    57 The Cray Fortran Compiler (ftn) on HLRNIII is known to be less flexible when it comes to the Fortran code style. In the following you find known issues observed at HLRNIII.

    5959* It is no longer allowed to use a space character between the variable name of an array (e.g. {{{mask_x_loop}}}) and the bracket "{{{(}}}".\\'''Example:'''\\{{{mask_x_loop (1,:) = 0., 500. ,50.,}}} (old)\\{{{mask_x_loop(1,:) = 0., 500. ,50.,}}} (new).
     
    148148   7. 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.

    150 The HLRNIII provides a brief online documentation for '''alinea''' (see https://www.hlrn.de/home/view/System3/AllineaDDT for details).
