New:
---
ocean version including prognostic equation for salinity and equation of state for seawater. Routine buoyancy can be used with both temperature and density.
+ inipar-parameters bc_sa_t, bottom_salinityflux, ocean, sa_surface, sa_vertical_gradient, sa_vertical_gradient_level, top_salinityflux

advec_s_bc, average_3d_data, boundary_conds, buoyancy, check_parameters, data_output_2d, data_output_3d, diffusion_e, flow_statistics, header, init_grid, init_3d_model, modules, netcdf, parin, production_e, prognostic_equations, read_var_list, sum_up_3d_data, swap_timelevel, time_integration, user_interface, write_var_list, write_3d_binary

New:

[62]	60	<ul> All hosts (local as well as remote) are
[5]	61	accessed via the secure shell (ssh). The user must establish

[62]	63	<a href="http://www.hlrn.de/doc/ssh/index.html">HLRN
	64	documentation</a>). <b>To ensure proper function of mrun,
	65	passwordless login must be
[5]	66	established in both directions, from the local to the remote host as
[62]	67	well as from the remote to the local host!</b> Test this by
	68	carrying
	69	out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">

	88	are
[5]	89	freely selectable (except <tt><font size="2">~/job_queue</font></tt>),
	90	however new users should use them as suggested, since many
	91	examples in this documentation as well as all example files are

	255	from version 3.2a, beside the default hosts (HLRN, etc.), PALM can also
	256	be installed and run on other Linux-Cluster-, IBM-AIX, or
	257	NEC-SX-systems. To configure PALM for a non-default host only requires
	258	to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;"> .mrun.config</span>.<br><br>First,
	259	you have to define the host identifier (a string of arbitrary length)
	260	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>"
	261	in case of an IBM-AIX- or NEC-SX-system, respectively. For example, if
	262	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
	263	the second step, you have to give all informations neccessary to
	264	compile and run PALM on your local host by adding an additional section
	265	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
	266	<5>      <host identifier> parallel<br>%netcdf_inc        <6>      <host identifier> parallel<br>%netcdf_lib        <7>      <host identifier> parallel<br>%fopts
	267	<8>      <host identifier> parallel<br>%lopts
	268	<9>      <host identifier> parallel<br></div><br>The
	269	section consists of four columns each separated by one or more blanks.
	270	The first column gives the name of the respective environment variable
	271	used by <span style="font-weight: bold;">mrun</span> and <span style="font-weight: bold;">mbuild</span>,
	272	while the second column defines its value. The third column has to be
	273	the host identifier as defined above, and the last column in each line
	274	must contain the string "<span style="font-family: Courier New,Courier,monospace;">parallel</span>".
	275	Otherwise, the respective line(s) will be interpreted as belonging to
	276	the setup for compiling and running a serial (non-parallel) version of
	277	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
	278	the preprocessor options to be invoked. In most of the cases, it will
	279	be neccessary to adjust the MPI data types to double precision by
	280	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
