[515]	11	Code installation<br>
	12	</font></h2>
[41]	13	<font color="#000000">This chapter
[515]	14	describes the installation of PALM on a Linux workstation (local host). There are two methods to install and run PALM. With the <span style="font-style: italic;">simple method</span>, you can run PALM interactively on the local computer. This method is using the scripts <span style="font-weight: bold;">palm_simple_install</span> and <span style="font-weight: bold;">palm_simple_run</span>.
	15	The simple method cannot create batch jobs itself, and cannot be used
	16	to create restart runs. Also file handling and most other features of
	17	the <span style="font-style: italic;">advanced method</span> are not available. This method is only recommended for those who like to test PALM quickly.<br>
	18	<br>
	19	The <span style="font-style: italic;">advanced method</span> is for running PALM in batch mode on a suitable remote computer. The installation procedure is using the script <span style="font-weight: bold;">mbuild</span>. All jobs are started on the local host using the script <b>mrun</b>. The PALM output is automatically sent back from the remote host to the
[62]	20	local host. Alternatively, <span style="font-weight: bold;">mrun</span>
[515]	21	can also be used to start PALM in interactive mode on the local host, or
	22	as a batch job on the local host (if a queueing system like NQS, PBS, or LoadLeveler is
	23	available).<br>
	24	<br>
	25	Only the <span style="font-style: italic;">advanced method</span> gives full access to all PALM features.<br>

	36	This is already included in many Linux distributions (e.g. SuSe). <span style="font-weight: bold;">subversion requires port 3690 to
	37	be open for tcp/udp.</span> <span style="font-weight: bold;">If
	38	there are firewall restrictions concerning this port, the PALM code
	39	cannot be accessed.</span> The

	41	please contact the PALM group (<a href="mailto:raasch@muk.uni-hannover.de">raasch@muk.uni-hannover.de</a>)
	42	and define a username under which you like to access the repository.

	73	</p><p style="line-height: 100%;">The installation
[515]	74	process for the <span style="font-style: italic;">advanced method</span> requires a valid

	80	All hosts (local as well as remote) are
[5]	81	accessed via the secure shell (ssh). The user must establish
	82	passwordless login using the private/public-key mechanism (see e.g. the
[290]	83	<a href="http://www2.hlrn.de/doc/ssh/index.html">HLRN
[62]	84	documentation</a>). <b>To ensure proper function of mrun,
	85	passwordless login must be
[5]	86	established in both directions, from the local to the remote host as
[62]	87	well as from the remote to the local host!</b> Test this by
	88	carrying
	89	out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">
	90	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	91	<username on remote host>@<remote
	92	IP-address></span><br> </p> <p style="line-height: 100%;">and on the remote host:<br>
	93	</p> <p style="line-height: 100%;"><span style="font-family: monospace;">
	94	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	95	<username on local host>@<local IP-adddress></span><br>
	96	</p> In both cases you should not be
	97	prompted for a password. <b>Before continuing the further
	98	installation
[515]	99	process, this must be absolutely guaranteed!</b> It must also
[62]	100	be
	101	guaranteed for <b>all</b> other remote hosts, on which
[290]	102	PALM shall run.<br><br>Please
[515]	103	note that on many remote hosts, passwordless login must also work <b>within the remote host</b>, i.e. for ssh connections from the
	104	remote host to itself. Test this by executing on the remote host:<br>
	105	<br>
	106	<span style="font-family: Courier New,Courier,monospace;">   ssh
	107	<username on remote host>@<remote IP-address></span>     .<br>
	108	<br>
	109	You should not be prompted

	113	Installation</span></p><p style="line-height: 100%;">The <b>first installation step</b> requires creating a
	114	set of directories on the local and, for the <span style="font-style: italic;">advanced method</span>, on the
	115	remote host<span style="font-style: italic;"></span>. These are:</p><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/job_queue<br></div><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/palm<br></div><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/palm/current_version<br></div><div style="margin-left: 40px;"><span style="font-family: Courier New,Courier,monospace;">~/palm/current_version/JOBS</span><br></div><p style="line-height: 100%;">The names of these directories can be
	116	freely selected (except <big><tt><font size="2"><big>~/job_queue</big></font></tt></big>),
	117	however new users should choose them as suggested, since many
	118	examples in this documentation as well as all example files are based on these settings. The directory <big><span style="font-family: monospace;">~/palm/current_version</span></big>

[83]	298	you have to define the host identifier (a string of arbitrary length)
