[62]	12	describes the installation of PALM on a Linux workstation (local host)
	13	and a suitable remote computer, on which the
[40]	14	model runs are to be carried out. The local host is used to
[62]	15	start batch jobs with <b>mrun</b> and to analyze the
	16	results
	17	which are produced by the model on the remote host and send back to the
	18	local host. Alternatively, <span style="font-weight: bold;">mrun</span>
	19	can also be used to start PALM on the local host in interactive mode or

[62]	49	examples given in this chapter refer to an
[287]	50	installation of PALM on an IMUK Linux workstation and the SGI-ICE
[5]	51	system of
[62]	52	the HLRN used as remote host. They are just called local and

	54	</p><p style="line-height: 100%;">The installation
	55	process requires a valid
[40]	56	account on the local and on the remote host as well.<br>
[5]	57	</p>
[62]	58	<ul> All hosts (local as well as remote) are
[5]	59	accessed via the secure shell (ssh). The user must establish
	60	passwordless login using the private/public-key mechanism (see e.g. the
[62]	61	<a href="http://www.hlrn.de/doc/ssh/index.html">HLRN
	62	documentation</a>). <b>To ensure proper function of mrun,
	63	passwordless login must be
[5]	64	established in both directions, from the local to the remote host as
[62]	65	well as from the remote to the local host!</b> Test this by
	66	carrying
	67	out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">
	68	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	69	<username on remote host>@<remote

	72	</span><span style="font-family: Courier New,Courier,monospace;">ssh
	73	<username on local host>@<local IP-adddress></span><br>
	74	</p> In both cases you should not be
	75	prompted for a password. <b>Before continuing the further
	76	installation
	77	process, this must be absolutely guaranteed!</b> This must also
	78	be
	79	guaranteed for <b>all</b> other remote hosts, on which
	80	PALM shall run.

	82	Installation</span></p><p style="line-height: 100%;">In
	83	the <b>first installation step</b> a
[5]	84	set of directories must be created both on the local and on the
[62]	85	remote host. These directories 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
	86	are
[5]	87	freely selectable (except <tt><font size="2">~/job_queue</font></tt>),
	88	however new users should use them as suggested, since many
	89	examples in this documentation as well as all example files are
[62]	90	assuming these settings. The directory <span style="font-family: monospace;">~/palm/current_version</span>
	91	on the local host will be called the working directory from now on. </p>

	256	from version 3.2a, beside the default hosts (HLRN, etc.), PALM can also
	257	be installed and run on other Linux-Cluster-, IBM-AIX, or
	258	NEC-SX-systems. To configure PALM for a non-default host only requires
	259	to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;"> .mrun.config</span>.<br><br>First,
	260	you have to define the host identifier (a string of arbitrary length)
	261	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  <hostname>  <host identifier></span><br></div><br>to the configuration file (best to do this in the section where the other default host identifiers are defined). Here<span style="font-family: Courier New,Courier,monospace;"> <hostname> </span>must be the name of your local host as provided by the unix-command "<span style="font-family: Courier New,Courier,monospace;">hostname</span>". The first characters of<span style="font-family: Courier New,Courier,monospace;"> <host identifier> </span>have to be "<span style="font-family: Courier New,Courier,monospace;">lc</span>", if your system is (part of) a linux-cluster, "<span style="font-family: Courier New,Courier,monospace;">ibm</span>", or "<span style="font-family: Courier New,Courier,monospace;">nec</span>"
	262	in case of an IBM-AIX- or NEC-SX-system, respectively. For example, if
	263	you want to install on a linux-cluster, the line may read as<br><br><div style="margin-left: 40px;">%host_identifier  foo  lc_bar<br></div><br>In
	264	the second step, you have to give all informations neccessary to
	265	compile and run PALM on your local host by adding an additional section
	266	to the configuration file:<br><br><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">%remote_username   <1>      <host identifier> parallel<br>%tmp_user_catalog  <2>      <host identifier> parallel<br>%compiler_name     <3>      <host identifier> parallel<br>%compiler_name_ser <4>      <host identifier> parallel<br>%cpp_options
	267	<5>      <host identifier> parallel<br>%netcdf_inc        <6>      <host identifier> parallel<br>%netcdf_lib        <7>      <host identifier> parallel<br>%fopts
	268	<8>      <host identifier> parallel<br>%lopts
	269	<9>      <host identifier> parallel<br></div><br>The
	270	section consists of four columns each separated by one or more blanks.
	271	The first column gives the name of the respective environment variable
	272	used by <span style="font-weight: bold;">mrun</span> and <span style="font-weight: bold;">mbuild</span>,
	273	while the second column defines its value. The third column has to be
	274	the host identifier as defined above, and the last column in each line
	275	must contain the string "<span style="font-family: Courier New,Courier,monospace;">parallel</span>".
	276	Otherwise, the respective line(s) will be interpreted as belonging to
	277	the setup for compiling and running a serial (non-parallel) version of
	278	PALM.<br><br>All brackets have to be replaced by the appropriate settings for your local host:<br><ul><li><span style="font-family: Courier New,Courier,monospace;"><1> </span>is the username on your LOCAL host</li><li><span style="font-family: Courier New,Courier,monospace;"><2> </span>is the temporary directory in which PALM runs will be carried out</li><li><span style="font-family: Courier New,Courier,monospace;"><3> </span>is the compiler name which generates parallel code</li><li><span style="font-family: Courier New,Courier,monospace;"><4> </span>is the compiler name for generating serial code</li><li><span style="font-family: Courier New,Courier,monospace;"><5> </span>are
	279	the preprocessor options to be invoked. In most of the cases, it will
	280	be neccessary to adjust the MPI data types to double precision by
	281	giving <span style="font-family: Courier New,Courier,monospace;">-DMPI_REAL=MPI_DOUBLE_PRECISION -DMPI_2REAL=MPI_2DOUBLE_PRECISION</span>. To switch on the NetCDF support, you also have to give <span style="font-family: Courier New,Courier,monospace;">-D__netcdf</span> and <span style="font-family: Courier New,Courier,monospace;">-D__netcdf_64bit</span> (if you like to have 64bit NetCDF output).</li><li><span style="font-family: Courier New,Courier,monospace;"><6> </span>is the compiler option for specifying the include path to search for the NetCDF module/include files</li><li><span style="font-family: Courier New,Courier,monospace;"><7> </span>are the linker options to search for the NetCDF library</li><li><span style="font-family: Courier New,Courier,monospace;"><8> </span>are the general compiler options to be used. You should allways switch on double precision (e.g. <span style="font-family: Courier New,Courier,monospace;">-r8</span>) and code optimization (e.g. <span style="font-family: Courier New,Courier,monospace;">-O2</span>).</li><li><span style="font-family: Courier New,Courier,monospace;"><9> </span>are the linker options</li><li><span style="font-family: Courier New,Courier,monospace;"><host identifier> </span>is the host identifier as defined before</li></ul><br>A typical example may be:<br><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">%remote_username
