[62]	13	describes the installation of PALM on a Linux workstation (local host)
	14	and a suitable remote computer, on which the
[40]	15	model runs are to be carried out. The local host is used to
[62]	16	start batch jobs with <b>mrun</b> and to analyze the
	17	results
	18	which are produced by the model on the remote host and send back to the
	19	local host. Alternatively, <span style="font-weight: bold;">mrun</span>
	20	can also be used to start PALM on the local host in interactive mode or

[62]	61	examples given in this chapter refer to an
[287]	62	installation of PALM on an IMUK Linux workstation and the SGI-ICE
[5]	63	system of
[62]	64	the HLRN used as remote host. They are just called local and

	66	</p><p style="line-height: 100%;">The installation
	67	process requires a valid
[40]	68	account on the local and on the remote host as well.<br>
[5]	69	</p>
[62]	70	<ul> All hosts (local as well as remote) are
[5]	71	accessed via the secure shell (ssh). The user must establish
	72	passwordless login using the private/public-key mechanism (see e.g. the
[290]	73	<a href="http://www2.hlrn.de/doc/ssh/index.html">HLRN
[62]	74	documentation</a>). <b>To ensure proper function of mrun,
	75	passwordless login must be
[5]	76	established in both directions, from the local to the remote host as
[62]	77	well as from the remote to the local host!</b> Test this by
	78	carrying
	79	out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">
	80	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	81	<username on remote host>@<remote

	84	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	85	<username on local host>@<local IP-adddress></span><br>
	86	</p> In both cases you should not be
	87	prompted for a password. <b>Before continuing the further
	88	installation
	89	process, this must be absolutely guaranteed!</b> This must also
	90	be
	91	guaranteed for <b>all</b> other remote hosts, on which
[290]	92	PALM shall run.<br><br>Please
	93	note that on many remote hosts, passwordless login must also be
	94	established <b>within the remote host</b>, i.e. from the
	95	remote host to itself. Test this by executing on the remote host: <span style="font-family: Courier New,Courier,monospace;">ssh
	96	<remote IP-address></span>. You should not be prompted
	97	for a password.<br><br></ul><p style="line-height: 100%;"><span style="font-weight: bold; text-decoration: underline;">Package

	99	the <b>first installation step</b> a
[5]	100	set of directories must be created both on the local and on the

	102	are
[290]	103	freely selectable (except <big><tt><font size="2"><big>~/job_queue</big></font></tt></big>),
[5]	104	however new users should use them as suggested, since many
	105	examples in this documentation as well as all example files are
[290]	106	assuming these settings. The directory <big><span style="font-family: monospace;">~/palm/current_version</span></big>
[62]	107	on the local host will be called the working directory from now on. </p>

[83]	284	from version 3.2a, beside the default hosts (HLRN, etc.), PALM can also
	285	be installed and run on other Linux-Cluster-, IBM-AIX, or
	286	NEC-SX-systems. To configure PALM for a non-default host only requires
[290]	287	to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;">
	288	.mrun.config</span>.<br><br>First,
[83]	289	you have to define the host identifier (a string of arbitrary length)
[290]	290	under which your local host shall be identified by adding a line<br><br></font><div style="margin-left: 40px;"><span style="font-family: Courier New,Courier,monospace;">%host_identifier
	291	<hostname>  <host
	292	identifier></span><br></div><br>to the
	293	configuration file (best to do this in the section where the other
	294	default host identifiers are defined). Here<span style="font-family: Courier New,Courier,monospace;">
	295	<hostname> </span>must be the name of your local
	296	host as provided by the unix-command "<span style="font-family: Courier New,Courier,monospace;">hostname</span>".
	297	The first characters of<span style="font-family: Courier New,Courier,monospace;">
	298	<host identifier> </span>have to be "<span style="font-family: Courier New,Courier,monospace;">lc</span>",
	299	if your system is (part of) a linux-cluster, "<span style="font-family: Courier New,Courier,monospace;">ibm</span>",
	300	or "<span style="font-family: Courier New,Courier,monospace;">nec</span>"
[83]	301	in case of an IBM-AIX- or NEC-SX-system, respectively. For example, if
[290]	302	you want to install on a linux-cluster, the line may read as<br><br><div style="margin-left: 40px;">%host_identifier  foo
	303	lc_bar<br></div><br>In
[83]	304	the second step, you have to give all informations neccessary to
	305	compile and run PALM on your local host by adding an additional section
[290]	306	to the configuration file:<br><br><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">%remote_username

	328	and <span style="font-weight: bold;">mbuild</span>,
[83]	329	while the second column defines its value. The third column has to be
	330	the host identifier as defined above, and the last column in each line
	331	must contain the string "<span style="font-family: Courier New,Courier,monospace;">parallel</span>".

[290]	344	giving <span style="font-family: Courier New,Courier,monospace;">-DMPI_REAL=MPI_DOUBLE_PRECISION
	345	-DMPI_2REAL=MPI_2DOUBLE_PRECISION</span>. To switch on the NetCDF
	346	support, you also have to give <span style="font-family: Courier New,Courier,monospace;">-D__netcdf</span>
	347	and <span style="font-family: Courier New,Courier,monospace;">-D__netcdf_64bit</span>
