9	Installation of the

11	<font color="#000000">This chapter
12	describes the installation of PALM on a Linux workstation (local host)
13	and a suitable remote computer, on which the
14	model runs are to be carried out. The local host is used to
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
20	as a batch job (if a queueing system like NQS, PBS, or LoadLeveler is

60	examples given in this chapter refer to an

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

83	</span><span style="font-family: Courier New,Courier,monospace;">ssh

85	</p> In both cases you should not be
86	prompted for a password. <b>Before continuing the further
87	installation
88	process, this must be absolutely guaranteed!</b> This must also
89	be
90	guaranteed for <b>all</b> other remote hosts, on which
91	PALM shall run.<br><br>Please
92	note that on many remote hosts, passwordless login must also be
93	established <b>within the remote host</b>, i.e. from the
94	remote host to itself. Test this by executing on the remote host: <span style="font-family: Courier New,Courier,monospace;">ssh
95	<remote IP-address></span>. You should not be prompted
96	for a password.<br><br></ul><p style="line-height: 100%;"><span style="font-weight: bold; text-decoration: underline;">Package
97	Installation</span></p><p style="line-height: 100%;">In
98	the <b>first installation step</b> a
99	set of directories must be created both on the local and on the
100	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
101	are
102	freely selectable (except <big><tt><font size="2"><big>~/job_queue</big></font></tt></big>),
103	however new users should use them as suggested, since many
104	examples in this documentation as well as all example files are
105	assuming these settings. The directory <big><span style="font-family: monospace;">~/palm/current_version</span></big>
106	on the local host will be called the working directory from now on. </p>

284	for other machines</font></p><font color="#000000">Starting
285	from version 3.2a, beside the default hosts (HLRN, etc.), PALM can also
286	be installed and run on other Linux-Cluster-, IBM-AIX, or
287	NEC-SX-systems. To configure PALM for a non-default host only requires
288	to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;">
289	.mrun.config</span>.<br><br>First,
290	you have to define the host identifier (a string of arbitrary length)
291	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
292	<hostname>  <host
293	identifier></span><br></div><br>to the
294	configuration file (best to do this in the section where the other
295	default host identifiers are defined). Here<span style="font-family: Courier New,Courier,monospace;">
296	<hostname> </span>must be the name of your local
297	host as provided by the unix-command "<span style="font-family: Courier New,Courier,monospace;">hostname</span>".
298	The first characters of<span style="font-family: Courier New,Courier,monospace;">
299	<host identifier> </span>have to be "<span style="font-family: Courier New,Courier,monospace;">lc</span>",
300	if your system is (part of) a linux-cluster, "<span style="font-family: Courier New,Courier,monospace;">ibm</span>",
301	or "<span style="font-family: Courier New,Courier,monospace;">nec</span>"
302	in case of an IBM-AIX- or NEC-SX-system, respectively. For example, if
303	you want to install on a linux-cluster, the line may read as<br><br><div style="margin-left: 40px;">%host_identifier  foo
304	lc_bar<br></div><br>In
305	the second step, you have to give all informations neccessary to
306	compile and run PALM on your local host by adding an additional section
307	to the configuration file:<br><br><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">%remote_username
308	<1>      <host
309	identifier> parallel<br>%tmp_user_catalog

323	identifier> parallel<br>%lopts
324	<9>
325	<host identifier> parallel<br></div><br>The
326	section consists of four columns each separated by one or more blanks.
327	The first column gives the name of the respective environment variable
328	used by <span style="font-weight: bold;">mrun</span>
329	and <span style="font-weight: bold;">mbuild</span>,
330	while the second column defines its value. The third column has to be
331	the host identifier as defined above, and the last column in each line
332	must contain the string "<span style="font-family: Courier New,Courier,monospace;">parallel</span>".
333	Otherwise, the respective line(s) will be interpreted as belonging to
334	the setup for compiling and running a serial (non-parallel) version of
335	PALM.<br><br>All brackets have to be replaced by the
336	appropriate settings for your local host:<br><ul><li><span style="font-family: Courier New,Courier,monospace;"><1>
337	</span>is the username on your LOCAL host</li><li><span style="font-family: Courier New,Courier,monospace;"><2>
338	</span>is the temporary directory in which PALM runs will be
339	carried out</li><li><span style="font-family: Courier New,Courier,monospace;"><3>
340	</span>is the compiler name which generates parallel code</li><li><span style="font-family: Courier New,Courier,monospace;"><4>
341	</span>is the compiler name for generating serial code</li><li><span style="font-family: Courier New,Courier,monospace;"><5>
342	</span>are
343	the preprocessor options to be invoked. In most of the cases, it will
344	be neccessary to adjust the MPI data types to double precision by
345	giving <span style="font-family: Courier New,Courier,monospace;">-DMPI_REAL=MPI_DOUBLE_PRECISION
346	-DMPI_2REAL=MPI_2DOUBLE_PRECISION</span>. To switch on the NetCDF
347	support, you also have to give <span style="font-family: Courier New,Courier,monospace;">-D__netcdf</span>
348	and <span style="font-family: Courier New,Courier,monospace;">-D__netcdf_64bit</span>
349	(if you like to have 64bit NetCDF output).</li><li><span style="font-family: Courier New,Courier,monospace;"><6>
350	</span>is the compiler option for specifying the include path to
351	search for the NetCDF module/include files</li><li><span style="font-family: Courier New,Courier,monospace;"><7>
352	</span>are the linker options to search for the NetCDF library</li><li><span style="font-family: Courier New,Courier,monospace;"><8>
353	</span>are the general compiler options to be used. You should
354	allways switch on double precision (e.g. <span style="font-family: Courier New,Courier,monospace;">-r8</span>)
355	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>
356	</span>are the linker options</li><li><span style="font-family: Courier New,Courier,monospace;"><host
