-PRELIMINARIES
+Please see the Moses website on how to compile and run Moses
+   http://www.statmt.org/moses/?n=Development.GetStarted
 
-Moses is primarily targeted at gcc on UNIX.  
-
-Moses requires gcc, Boost >= 1.36, and zlib including the headers that some
-distributions package separately (i.e. -dev or -devel packages).  Source is
-available at http://boost.org .
-
-There are several optional dependencies:
-
-GIZA++ from http://code.google.com/p/giza-pp/ is used to align words in the parallel corpus during training.
-
-Moses server requires xmlrpc-c with abyss-server.  Source is available from
-http://xmlrpc-c.sourceforge.net/.  
-
-The scripts support building ARPA format language models with SRILM or IRSTLM.
-To apply models inside the decoder, you can use SRILM, IRSTLM, or KenLM.  The
-ARPA format is exchangable so that e.g. you can build a model with SRILM and
-run the decoder with IRSTLM or KenLM.
-
-If you want to use SRILM, you will need to download its source and build it.  
-The SRILM can be downloaded from 
-http://www.speech.sri.com/projects/srilm/download.html .
-On x86_64, the default machine type is broken.  Edit sbin/machine-type, find
-this code
-    else if (`uname -m` == x86_64) then
-        set MACHINE_TYPE = i686
-and change it to
-    else if (`uname -m` == x86_64) then
-        set MACHINE_TYPE = i686-m64
-You may have to chmod +w sbin/machine-type first.  
-
-If you want to use IRSTLM, you will need to download its source and build it.  
-The IRSTLM can be downloaded from either the SourceForge website
-http://sourceforge.net/projects/irstlm
-or the official IRSTLM website
-http://hlt.fbk.eu/en/irstlm
-
-KenLM is included with Moses.

-
-ADVICE ON INSTALLING EXTERNAL LIBRARIES
-
-Generally, for trouble installing external libraries, you should get support
-directly from the library maker:
-
-Boost: http://www.boost.org/doc/libs/release/more/getting_started/unix-variants.html
-IRSTLM: https://list.fbk.eu/sympa/subscribe/user-irstlm
-SRILM: http://www.speech.sri.com/projects/srilm/#srilm-user
-
-However, here's some general advice on installing software (for bash users):
-
-#Determine where you want to install packages
-PREFIX=$HOME/usr
-#If your system has lib64 directories, lib64 should be used AND NOT lib  
-if [ -d /lib64 ]; then
-  LIBDIR=$PREFIX/lib64
-else
-  LIBDIR=$PREFIX/lib
-fi
-#If you're installing to a non-standard path, tell programs where to find things:
-export PATH=$PREFIX/bin${PATH:+:$PATH}
-export LD_LIBRARY_PATH=$LIBDIR${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
-export LIBRARY_PATH=$LIBDIR${LIBRARY_PATH:+:$LIBRARY_PATH}
-export CPATH=$PREFIX/include${CPATH:+:$CPATH}
-
-Add all the above code to your .bashrc or .bash_login as appropriate.  Then
-you're ready to install packages in non-standard paths:
-
-#For autotools packages e.g. xmlrpc-c and zlib
-./configure --prefix=$PREFIX --libdir=$LIBDIR [other options here]
-
-#tcmalloc is a malloc implementation with threaded performance.  To see how it
-#improves Moses performance, read
-# http://www.mail-archive.com/moses-support@mit.edu/msg07303.html
-#It is part of gperftools which can be downloaded from from
-# https://code.google.com/p/gperftools/downloads/list
-#configure with this:
-./configure --prefix=$PREFIX --libdir=$LIBDIR --enable-shared --enable-static --enable-minimal
-
-#For bzip2:
-wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
-tar xzvf bzip2-1.0.6.tar.gz
-cd bzip2-1.0.6/
-#Compile and install libbz2.a (static library)
-make
-make install PREFIX=$PREFIX
-mkdir -p $LIBDIR
-#Note this may be the same file; you can ignore the error
-mv $PREFIX/lib/libbz2.a $LIBDIR 2>/dev/null
-#Compile and install libbz2.so (dynamic library)
-make clean
-make -f Makefile-libbz2_so
-cp libbz2.so.* $LIBDIR
-ln -sf libbz2.so.1.0 $LIBDIR/libbz2.so
-
-#For Boost:
-./bootstrap.sh
-./b2 --prefix=$PWD --libdir=$PWD/lib64 --layout=tagged link=static,shared threading=multi,single install || echo FAILURE
-
-This will put the header files and libraries files in the current directory, rather than the system directory.
-
-For most Linux systems, you should replace
-  link=static,shared
-with
-  link=static
-so it will only create static libraries. The minimised headaches when linking with Moses. 
-
-To link Moses to your version of boost,
-   ./bjam --with-boost=[boost/path]
-
-Alternatively, you run 
-   ./b2 --prefix=/usr/ --libdir=/usr/lib
-to install boost in the systems folder. However, this may override the built in boost and causes problems for your OS, therefore, it is not recommended.
-
---------------------------------------------------------------------------
-
-BUILDING
-
-Building consists of running
-  ./bjam [options]
-
-Common options are:
---with-srilm=/path/to/srilm to compile the decoder with SRILM support
---with-irstlm=/path/to/irstlm to compile the decoder with IRSTLM support
--jN where N is the number of CPUs
-
---with-macports=/path/to/macports use MacPorts on Mac OS X.
-
-If you leave out /path/to/macports bjam will use the /opt/local as default.
-You don't have to use --with-boost with-macports as it is implicitly set.
-Also note that using --with-macports automatically triggers "using darwin".
-
-Binaries will appear in dist/bin.  
-
-You can clean up data from previous builds using
-  ./bjam --clean
-
-For further documentation, run 
-  ./bjam --help
-
---------------------------------------------------------------------------
-
-ALTERNATIVE WAYS TO BUILD ON UNIX AND OTHER PLATFORMS
-
-Microsoft Windows
------------------
-Moses is primarily targeted at gcc on UNIX.  Windows users should
-install using Cygwin. Outdated instructions can be found here:
-http://ssli.ee.washington.edu/people/amittai/Moses-on-Win7.pdf .
-
-Binaries for all external libraries needed can be downloaded from 
-	http://www.statmt.org/moses/?n=Moses.LibrariesUsed
-
-Only the decoder is developed and tested under Windows. There are
-difficulties using the training scripts under Windows, even with
-Cygwin, but it can be done.

+MERT-sge-nosync
+Raymond Ng, University of Sheffield.
+Apr, 2014.
+
+The parallel MERT tuning scripts in moses cannot run in the SGE "no-sync" mode (where job submission is done in one go, after which user can go offline while leaving the SGE to manage the whole process). Scripts provided in this site are for parallel MERT in SGE no-sync mode. You will need to have SSH support in perl (Step 2), and set up public ssh-keys between the running hosts and the submission hosts (Step 3).
+ 
+1. Untar the scipts in ${MOSES}/scripts/
+
+2. Download and install OpenSSH packages for perl:
+Net-OpenSSH-Compat  (http://search.cpan.org/CPAN/authors/id/S/SA/SALVA/Net-OpenSSH-Compat-0.06.tar.gz)
+$ cd Net-OpenSSH-Compat-0.06
+$ perl Makefile.PL
+(You may have dependency issue and need to install IO-Tty and Net-OpenSSH in advance)
+IO-Tty-1.10       (http://search.cpan.org/CPAN/authors/id/T/TO/TODDR/IO-Tty-1.10.tar.gz)
+Net-OpenSSH-0.60  (http://search.cpan.org/CPAN/authors/id/S/SA/SALVA/Net-OpenSSH-0.60.tar.gz)
+
+3. Set up public ssh-keys for accessing the submithost (machine from which qsub is executed) from the running hosts (machines which actually runs the scripts)
+http://www.linuxproblem.org/art_9.html
+
+4. Run parallel MERT by
+nohup nice ${MOSES}/scripts/training/mert-moses-sge-nosync.pl ${TM_DEVTEXT_SOURCE} \
+--threads 20 --jobs 20 \
+--queue-flags='-q normal.q -P project' \
+--submithost='squeal' \
+${TM_DEVTEXT_TARGET} ${MOSES}/dist/bin/moses ${WORKINGDIR}/train/model/moses.ini \
+--mertdir ${MOSES}/dist/bin/ >& ${WORKINGDIR}/mert.out
+
+

+# 5 Aug 2009  Handling with different reference length policies (shortest, average, closest) for BLEU 
+#             and case-sensistive/insensitive evaluation (Nicola Bertoldi)
+# 5 Jun 2008  Forked previous version to support new mert implementation.
+# 13 Feb 2007 Better handling of default values for lambda, now works with multiple

+# 11 Oct 2006 Handle different input types through parameter --inputype=[0|1]
