18 | <font color="#000000">This chapter |
---|
19 | describes the installation of PALM on a Linux workstation (local host) and a suitable remote computer, on which the |
---|
20 | model runs are to be carried out. The local host is used to |
---|
21 | start batch jobs with <b>mrun</b> and to analyze the results |
---|
22 | which are produced by the model on the remote host and send back to the local host. Alternatively, <span style="font-weight: bold;">mrun</span> can also be used to start PALM on the local host in interactive mode or as a batch job.</font><p style="line-height: 100%;"><font color="#000000"></font></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 installation and operation of PALM requires at mimimum (on both, the local and the remote host, unless stated otherwise):</font></p><ol><li><font color="#000000">The AT&T Korn-shell (ksh) must be available under<span style="font-family: Courier New,Courier,monospace;"> </span></font><font style="font-family: Courier New,Courier,monospace;" color="#000000">/bin/ksh</font><font color="#000000">.

29 | installation of PALM on an IMUK Linux workstation and the IBM-Regatta |

35 | </p> |
---|
36 | <ul> |
---|
37 | All hosts (local as well as remote) are |

38 | accessed via the secure shell (ssh). The user must establish |

40 | <a href="http://www.hlrn.de/doc/ssh/index.html">HLRN documentation</a>). |

41 | <b>To ensure proper function of mrun, passwordless login must be |
---|
42 | established in both directions, from the local to the remote host as |
---|
43 | well as from the remote to the local host!</b> Test this by carrying |
---|
44 | out e.g. on the local host: |
---|
45 | <p style="line-height: 100%;"><span style="font-family: monospace;"> |
---|
46 | </span><span style="font-family: Courier New,Courier,monospace;">ssh <username on remote host>@<remote IP-address></span><br> |

53 | In both cases you should not be |

54 | prompted for a password. <b>Before continuing the further installation |

59 | set of directories must be created both on the local and on the |

61 | freely selectable (except <tt><font size="2">~/job_queue</font></tt>), |

62 | however new users should use them as suggested, since many |

63 | examples in this documentation as well as all example files are |

64 | assuming these settings. The directory <span style="font-family: monospace;">~/palm/current_version</span> on the local host will be called the working directory from now on. </p> |
