[41]12<font color="#000000">This chapter
[62]13describes the installation of PALM on a Linux workstation (local host)
14and a suitable remote computer, on which the
[40]15model runs are to be carried out. The local host is used to
[62]16start batch jobs with <b>mrun</b> and to analyze the
17results
18which are produced by the model on the remote host and send back to the
19local host. Alternatively, <span style="font-weight: bold;">mrun</span>
20can also be used to start PALM on the local host in interactive mode or
21as a batch job.</font><p style="line-height: 100%;"></p><p style="line-height: 100%;"><font color="#000000"><span style="font-weight: bold; text-decoration: underline;">Requirements</span></font></p><p style="line-height: 100%;"><font color="#000000">The

80out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">&nbsp;&nbsp;&nbsp;
