README file for HPCServer Grid Scheduler
=======================================


- System requeriments, and software versions used in this platform:

	CentOS 6.x x86_64
	Python 2.4.4
	ZeroC Ice 3.4.0 


HPCServer Grid Scheduler configuration step-by-step
==================================================

Primary Registry configuration
------------------------------

1 - Unprivileged user creation for security reasons.

adduser executor
su - executor

2 - Working dir of HPCServer Grid Scheduler:

mkdir Ice
cd Ice

3 - Install Python 2.4.4 the only tested platform:

wget http://www.python.org/ftp/python/2.4.4/Python-2.4.4.tar.bz2
tar xvjf Python-2.4.4.tar.bz2
cd  Python-2.4.4
./configure --prefix=/home/executor/Ice/python2.4
make
make install

4 -  IceGrid 3.4.0 deployment:

mkdir download && cd download
wget wget http://zeroc.com/download/Ice/3.4/Ice-3.4.0-rhel5-x86_64-rpm.tar.gz
tar xvzf Ice-3.4.0-rhel5-x86_64-rpm.tar.gz
cd /home/executor/Ice
rpm2cpio download/ice-3.4.0-1.rhel5.noarch.rpm | cpio -ivd
rpm2cpio download/ice-python-3.4.0-1.rhel5.x86_64.rpm | cpio -ivd
rpm2cpio download/ice-libs-3.4.0-1.rhel5.x86_64.rpm | cpio -ivd

rpm2cpio download/db48-4.8.24-1ice.rhel5.x86_64.rpm | cpio -ivd

rm -fr etc

5 - Minimal folder staff:

mkdir -p /home/executor/Ice/var/run /home/executor/Ice/var/lib/icegrid/registry /home/executor/Ice/var/lock/subsys

6 - Primary Registry configuration files:

cp -r liberacion-github/etc_config/primary-registry/etc /home/executor/Ice

7 - Running the Primary Registry:

[executor@host001 ]$ /home/executor/Ice/etc/init.d/icegridregistry start
Starting icegridregistry:                                  [  OK  ]


Secondary Registry configuration
--------------------------------

Repeat step from 1 to 5:

6 - Secondary Registry configuration files:

cp -r liberacion-github/etc_config/secondary-registry/etc /home/executor/Ice


7 - Running the Secondary Registry:

[executor@host002 ]$ /home/executor/Ice/etc/init.d/icegridregistry start
Starting icegridregistry:                                  [  OK  ]

Node configuration
------------------

Repeat step from 1 to 4:

5 - Minimal folder staff:

mkdir -p /home/executor/Ice/var/run /home/executor/Ice/var/lib/icegrid/node /home/executor/Ice/var/lock/subsys

6 - Execution Node configuration files:

cp -r liberacion-github/etc_config/node/etc /home/executor/Ice

7 - Running the Execution Node:

[executor@host003 ~]$ /home/executor/Ice/etc/init.d/icegridnode start
Starting icegridnode:                                      [  OK  ]


Testing the installation
------------------------

- Setting up the minimal enviroment:

ICEGRID_HOME=/home/executor
PYTHONPATH=$ICEGRID_HOME/Ice/usr/lib64/python2.4/site-packages/Ice/:$ICEGRID_HOME/Ice/python2.4/lib/python2.4/ 
LD_LIBRARY_PATH=$ICEGRID_HOME/Ice/usr/lib64/ 
PATH=$PATH:/home/executor/Ice/usr/bin/
export PYTHONPATH LD_LIBRARY_PATH PATH

- Checking the IceGrid components deployed:

[executor@host001 ~]$ cat config.cfg 
Ice.Default.Locator=HPCBanestoGrid/Locator:tcp -h host001 -p 4061

[executor@host001 ~]$ Ice/usr/bin/icegridadmin  --Ice.Config=config.cfg -u executor -p xxx

Octave framework configuration
------------------------------

yum install octave hdf5
ln -sf /usr/lib64/libhdf5.so.7 /usr/lib64/libhdf5.so.6

Node executor staff
-------------------

You have to deploy on each executor node this folder in order to run
the Monte Carlo pricing simulation with octave.

home/executor/ameba
└── 364
    ├── ameba.sh
    └── AsianOption.m

Client execution
---------------

cd CLIENT
sh directTest.sh

{{ putPrice  0.35879 callPrice  0.49347 }}
{{ putPrice  0.35819 callPrice  0.49189 }}

Notes
-----

This sample of IceGrid from ZeroC Ice shows the execution of Monte Carlo Asian 
Pricing simulation using Octave. The code is ready to set up different 
Octave enviroments.
