How do I log into the same login or pp node I used before¶
mistral.dkrz.de or mistralpp maps to a whole group of nodes to distribute the load. They all share the same file system so most of the time you do not have to care which node you are on. However, there are reasons why you may want to connect to a specific node. You first have to find out on which node you are. This may be indicated in your prompt or you can also use hostname for this purpose.
b999009@mlogin103% hostname
mlogin103
In this case you are on login node 3. Connect to this node with
ssh mistral03.dkrz.de
For mistralpp, the scheme is the same.
Please keep in mind that login nodes are not intended for long running and computationally intensive tasks. Use batch jobs for this kind of activity.
