== How to expand the storage on fallopius ==

* You are the admin, right?
* Login as root and shutdown the machine
* Install the physical drives (currently, use only 1TB drives!). Turn on the machine.
* Enter the RAID bios by pressing TAB
* Enter the rsf menu and choose to expand the array (this operation took around 33 hours for 4Tb -> 6Tb expansion!!!)
* Enter the vsf menu and choose to expand also the logical array (this operation took only around 1 hour for 4Tb -> 6Tb expansion)
* Boot the system
* umount /home/; umount /storage/volume0; umount /storage/volume1
* Execute parted
* Select /dev/sdb. From now on we assume that in the system there exist, so far, logical partitions /dev/sdb1, /dev/sdb2, ..., /dev/sdb(n-1)
* Create a new partition, start at [old_size] (size before the RAID expansion), end at [new_size] (size after the RAID expansion). At the end of the process, a new partition is created and henceforth denoted as /dev/sdbn
* pvcreate /dev/sdbn

Backup Server

2012-02-14T17:49:28Z

Eliseo: /* Backup Software */

= IRIDIA Backup System =

== Personal Backups ==

Everyone has 20GB available space on fallopius. You are responsible for backup up your own data into the space you have allocated on fallopius.

=== Push Backup ===

Backups are initiated from the client machine ("pushed" onto the server).

You can use you personal favourite to push your backups on the server. Please make sure that your data does not exceed the limit (i.e. purge old data regularly).

Examples of good backup programs are rdiff-backup, rsync, hdup, unison and many others. See below for a list .

=== Pull Backup ===

Backups are initiated from the backup server ("pulled").

==== Halva's old system ====

There is an old automated backup system that is still in place, but no longer supported. It was written by Halva and uses rdiff-backup. A script pulls the contents of the user's home directory onto the backup server. Instructions here: [[Old Backup System (Halva's rdiff system)]]. Good luck.

== Server Backup ==

=== iridia.ulb.ac.be ===

All data on the iridia server is backed up by a separate (supported) nightly script that uses dar (see below). This is an incremental backup program that is like a network version of tar. The scripts are run by the crontab of the user servicebackup on iridia using the script /home/servicebackup/iridia_service_backup_system/backup.sh. The shell functions that do the meat of the work are included from the file include.sh in the same directory.

The backed up data is stored in the directory are stored on fallopius in the directory /home/iridiaserver/service_backup_dar.
To restore data you will need to familiarise yourself with the dar program, or use the script /home/servicebackup/iridia_service_backup_system/restore.sh on iridia.

The data that is backed up is divided into 'services'. A list of these services can be found in the directory /home/servicebackup/iridia_service_backup_system/services. Each service is a directory that must at a minimum contain scripts called <SERVICE_NAME>_backup.sh and <SERVICE_NAME>_restore.sh. These two scripts should make use of the functions provided by the file /home/servicebackup/iridia_service_backup_system/include.sh which provide wrappers around the dar commands. Optionally, inside each service directory there can be scripts called <SERVICE_NAME>_suspend.sh and <SERVICE_NAME>_resume.sh which will be called before and after the backup, and can be used to stop and start any processes that might interfere with the integrity of the backed up data if they are left running.

A mail gets sent every day to a list of addresses defined in the backup.sh script with the success / failure of the backup in the subject line.

===== Troubleshooting =====

Logfiles for each backup are stored in /home/servicebackup/iridia_service_backup_system/log on iridia.ulb.ac.be

A quick way of debugging the system is to run the script /home/servicebackup/iridia_service_backup_system/just_test_backup.sh . This script does a test backup of a small directory and outputs to the logfile test.log.

There is an ugly soft link from /usr/lib/libdar.so.3.0.1 -> /home/iridiaserver/dar/lib/libdar.so.3.0.1 This link has been known to disappear after an upgrade of the system.

===== svn =====

The scripting system is maintained and versioned in the svn repository:
file:///usr/local/share/svn_repositories/iridia_service_backup_system

== Backup Software ==

=== dar ===

DAR (http://dar.sourceforge.net/) is an incremental backup program that is like a network version of tar. It is used by the iridia server.

=== rdiff-backup ===

The current supported version is 1.1.17. Follow the steps below for Debian etch:

$ wget http://iridia.ulb.ac.be/~abrutschy/rdiff-backup_1.1.17-1_etch_i386.deb
$ sudo dpkg -i rdiff-backup_1.1.17-1_etch_i386.deb

and for Ubuntu Intrepid/Debian Lenny:

$ wget http://iridia.ulb.ac.be/~abrutschy/rdiff-backup_1.1.17-1_lenny_intrepid_i386.deb
$ sudo dpkg -i rdiff-backup_1.1.17-1_lenny_intrepid_i386.deb

and for Ubuntu Jaunty:

$ wget http://iridia.ulb.ac.be/~abrutschy/rdiff-backup_1.1.17-1_jaunty_i386.deb
$ sudo dpkg -i rdiff-backup_1.1.17-1_jaunty_i386.deb

In case you use another system, download and install from the source ( http://iridia.ulb.ac.be/wiki/images/1/18/Rdiff-backup_1.1.17.orig.tar.gz or http://download.savannah.gnu.org/releases/rdiff-backup/rdiff-backup-1.1.17.tar.gz). Note that it could not work if your system has a version that is different).

Add the following lines to "/etc/apt/preferences" in order to prevent apt to install another version of rdiff-backup:

Package: rdiff-backup
Pin: version 1.1.17-1
Pin-Priority: 1001

===== Clean up some of your used space =====

Imagining that you don't need the entire history of your backup, you can use rdiff to delete files that are older than a specified amount of time.

/usr/bin/rdiff-backup -v0 --force --remove-older-than 3W <fallopiususername>@fallopius::/home/<fallopiususername>/backup/<localusername>@<localmachine>.ulb.ac.be/

Please use once in a while

=== Unison ===

If you know unison, note that you can also use that for your personal backups. Installed version is 2.27.57. For documentation look here http://www.cis.upenn.edu/~bcpierce/unison/.

Eliseo:

In this page you can find instructions on how to use the new Iridia Supplementary Information page.
Every person should transfer all the supplementary information (videos, images, pictures, graphs, etc.) in this page and for every paper that contains this kind of information, create an entry.
The structure is as follows:
* There is the page http://iridia.ulb.ac.be/supp in which we keep record of all the papers containing supplementary information, with a link leading to a dedicated page containing this info.
* Under /supp/ there are directories, one for each paper, containing all the media plus an index.html file

=== Procedure for adding supplementary material ===

The procedure is the following:

# People should contact the [[Lab_responsibilities|responsible of the supplementary pages]], who will create a directory under http://iridia.ulb.ac.be/supp/ with the title IridiaSupp200x-00x, with the numbering according to the year of the paper and the rank it gets for that year. Papers will acquire an ascending number (first who asks for a number gets it). At the same time, the publication details of the paper should be provided to the [[Lab_responsibilities|responsible of the supplementary pages]] and he will upload them to the SUPP page.
# Once every user has her/his directory, (s)he should
## create an index.html page which should contain ALL the information referred to in the paper. It can potentially include extra text. See http://iridia.ulb.ac.be/supp/IridiaSupp2006-001/index.html for an excellent example by Max.
## create a compressed file with all the supplementary information (images, videos, etc) in her/his directory, and USE LOCAL LINKS in hers/his index.html pages
## give the compressed file to the [[Lab_responsibilities|responsible of the supplementary pages]]

=== Procedure for moving old material to the supplementary material page ===

From now on ONLY this way of using supplementary information should be used. In case though, in old papers you have included links to pages e.g. in your own homepages or hosted on your machine, THEN, what should be done is the following:

# once again produce the index.html page, can be a copy of your old cited page
# copy all the files in the directory IridiaSupp200x-00x
# REDIRECT YOUR OLD CITED PAGE TO THIS NEW ONE with sth like:<pre><meta HTTP-EQUIV="REFRESH" content="0; url=http://iridia.ulb.ac.be/supp/IridiaSupp200x-00x/index.html"></pre>

=== Adding streaming video ===

To add a streaming video, please use HTML5. The simple procedure is the following.

# Add the tag <pre><video src="video.ogg" controls="controls">Your browser does not support the video tag.</video></pre>
# Convert your avi to ogg with <pre> ffmpeg -i video.avi -acodec libvorbis -ac 1 -b 768k video.ogg </pre>
# Place video.ogg in IridiaSupp200x-00x

=== Questions? ===

In case you have any questions, please contact the [[Lab_responsibilities|responsible of the supplementary pages]].

'''''Abstract and Reading Material'''''

Particle Swarm Optimization (PSO for short) was first inspired by the flocking behavior of birds, although it also has roots in some theories of social adaptation.
PSO is a population-based optimization technique in which each individual or "particle" represents a solution to a continuous optimization problem. Associated
with each particle, there is a velocity vector that changes according to its own best past performance and that of its neighbors. In this way, particles "fly"
over the search space resembling the movement of insects in a swarm.

After its first publication, PSO has attracted the interest of a growing research community because it is conceptually simple, technically easy to implement,
and has been successfully applied to many problems.

In this meeting, a brief overview of what has been done in PSO research and possible future work will be presented.

# '''Presentation / Discussion'''
#* Evolutionary Transitions in Solution Complexity

'''''Abstract'''''<br>
Recently, Evolutionary Biology has proposed a generalised theory for the origin of complexity in biological systems. This theory, referred to as Evolutionary Transition Theory, provides a description on how complexity could have arisen out of the interaction of simple components. A well-known example is the transition from single cell to multi-cellularity. As evolution itself, this theory provides a metaphor for optimisation and learning where complex solutions are constructed through the evolutionary combination of partial ones. This talk discusses a new evolutionary algorithm based on this metaphor. We show that, in the context of constraint satisfaction problems, this metaphor provides a very useful technique to find solutions. Moreover, the results of this basic, unoptimised algorithm are close to what is observed in other highly-adjusted evolutionary techniques. As a consequence, it provides an important foundation for the further investigation of compositional algorithms in the context of optimisation

'''''Agenda'''''

# '''Introduction'''
# '''Presentation / Discussion'''
#* Empirical analysis of stochastic algorithms by measuring run-time distributions
# '''MEETOPT Admin (10-15 mins)'''
#* Follow-up of the meeting about optimization libraries, tools etc. of the previous week

'''''Linked Presentations'''''

'''''Abstract and Reading Material'''''<br>
We start now the part of presentations / discussions on specific topics. The first topic to be discussed in a number of presentations / discussions is the '''Empirical Analysis of Algorithms, in particular SLS Algorithms'''. In this series we will discuss methods for their empirical analysis including run-time distributions, statistical analysis (hypothesis tests, ANOVA and alike methods), experimental design, tuning of algorithms, etc. We start this series by a presentation about the empirical analysis of algorithms through measuring run-time distributions. The presentation will be based on Chapter 4 of the book about ''Stochastic Local Search: Foundations and Applications'' by Holger Hoos and Thomas. The slides for the presentation are available via [http://www.sls-book.net SLS:FA] (check for the slides and figures section). The presentation will discuss only a small selection of the most important issues presented there.<br>

==Thursday 2nd February - Thomas STÃTZLE==

'''''Agenda'''''

Below is a list of topics that we will cover on empirical analysis. Since these topics in part also have to be elaborated from scratch, we will switch to the envisaged bi-weekly meeting, that is have roughly every two weeks one meeting. The topics below will be elaborated by the people participating in the seminar. This Thursday, Feb 2, we willl have a short meeting where we distribute the responsabilites of the tasks.

On Thursday everybods needs to have a lists of his two main preferred tasks so that we make the decision on who takes over what part.

We will also shortly discuss the state for the more practical directions.

In any case, the meeting on Thursday should be finished after 10 - 15 minutes max.

Topics on Empirical Analysis:

- Statistical Analysis (hypothesis tests -- param, non-param, permutation; stability of estimates -- confidence intervals; various situations of things to test -- correlation, metric measures, binary tests etc.) Maybe follow some text-book (Sheshkin / Siegel Castellan)

- Experimental Design (ANOVA and non-parametric analysis; planning of experiments; methodologies -- factorial designs, response surface methodology; follow some book: Montgomery / Dean, Voos etc.)

- Exploratory data analysis (usage of plots to illustrate things ?); Take ideas here from published papers, maybe some book about exploratory data analysis..

- Automated tuning of metaheuristics (overview of methods, issues); Overview of published papers plus new directions of work ..

- Integration of experimental methodologies in the design of algorithms; still fuzzy, to be defined.

'''Results'''

We will read and discuss the book chapter by chapter. For each chapter, one person will be responsable to lead the discussion by a short presentation. However, it is expected that everybody present in the meeting has already read through the material; in fact, reading the material is important to make the meetings effective.

The current schedule for the meetings is as follows.

- Feb 16, Marco M.: Empirical Research + Exploratory Data Analysis

- March 23, Anders: Basic Issues in Experiment Design

- March 29, Max: Hypothesis Testing and Estimation

- April 20, Christophe: Computer-Intensive Statistical Methods

- May 4, Shervin: Performance Assessment

- May 18, Prasanna: Explaining Performance: Interactions and Dependencies

- June 1, Roderich: Modeling

- June 15, Alexandre: Tactics for Generalization

'''''Paper Info'''''

* '''Title'''
** Ant clustering with locally weighted ant perception and diversified memory

* '''Authors'''
** Gilbert L. Peterson, Christopher B. Mayer, Thomas L. Kubler

* '''Summary'''
** The paper introduces two improvements to existing state of the art clustering algorithm based on ants. The first is the use of kernel functions as a way to increase the local perception capabilities of ants, enabling them to better distinguish between similar and dissimilar objects in their neighborhood. The second is the introduction of similarity-based memory, i.e. a very simple memory that can be equipped into single ants or in the entire ant colony and enables a better exploitation of the past experience. Results show that these improvements yield to better clustering quality and performance.

'''''Reading material'''''

* The paper is not yet published so it cannot be distributed in pdf. Paper copies can be obtained passing by Eliseo's office.
