PRE-REQUISITE: LUA and LMOD
----------------------------------------------------------
1. Install Lua from LMOD's sourceforge 
(already include luafilesystem & luaposix needed by LMOD)

go to http://sourceforge.net/projects/lmod/files/lua-5.1.4.8.tar.gz/download

OR
wget 

tar -xf lua-5.1.4.8.tar.gz
cd lua-5.1.4.8/
./configure --prefix=$XALT_DIR
make && make install

2. Install Lmod (Optional, needed if wanted to track module names)
git clone https://github.com/TACC/Lmod.git
./configure --prefix=$XALT_DIR
make install



INSTALLING XALT
-----------------------------------------------------------

1. Installation

git clone https://github.com/Fahey-McLay/xalt.git

cd xalt
./configure --prefix=$XALT_DIR --with-etcDir=$XALT_DIR/etc
make 
make install

cd ../bin
rm ibrun* mpirun mpiexec srun

2. Manual configuration

- Modify $XALT_DIR/site/xalt_syshost_default.py
mv site/xalt_syshost_default.py site/xalt_syshost.py 

- Modify $XALT_DIR/site/xalt_find_exec_aprun.py (likely not necessary)

- Create modulefile

- Create DB config file, and put them in XALT_ETC_DIR

python sbin/conf_create.py --> xalt_db.conf

python sbin/createDB.py (may need to be run from $XALT_ETC_DIR)
