Enabling Grids for E-sciencE
Introduction to web portals

Web Portal
Enabling Grids for E-sciencE
• A web portal is used to provide an easier way to run
jobs or applications on the grid for the users
• Avoids users needing to learn complex command line
interfaces to the Grid
• It can be accessed from everywhere and by
“everything” (desktop, laptop, PDA, mobile phone).
• It can keep the same user interface to several backends (including the switch to new EGEE middleware).

Web portal
Enabling Grids for E-sciencE
• Some examples of web portals:

Genius
Auvergui
AWP (Auvergrid Web Portal)
BIG (blast in grid)
Pgrade
• Differences between portals
– Difficulty to use it(knowledge of jdl files, certificates,
proxy,…)
– Specificity
– Security

Why use a Web portal
Enabling Grids for E-sciencE
• It can be accessible from everywhere, the only
condition is to have a valid certificate in your browser
• The same interface can be used, it’s independant of
the middleware
• The web interface is user-friendly

AWP
Enabling Grids for E-sciencE
• AWP (Auvergrid Web Portal)
• Web portal for biologists that provides some biological
tools

Blast
Est2genome
Secured bl2seq
Secured readseq
Repeatmasker
Hmmpfam
• The goal is to help biologists run their applications
faster on the Auvergrid grid, with more security than
on « traditional » web sites

How does it work?
Enabling Grids for E-sciencE
• Data:
– Software installed on the CE
 Role of the software_manager
– Biological Databases stored on SEs
– Instance Database stored on the Web server
• Princip:
– The software manager installs the software on each CE,
and the specified databases on SEs
– The web portal is developed on the web server
– The grid pipeline is installed on the UI. Goal:
 Get the parameters of the instance
 Create jobs, launch them on the grid
 Get the status, the results, and store them in the Instance
Database

Hands-on
Enabling Grids for E-sciencE
• During the practical session, you will use the
auvergrid-blast web portal:
– First you need to connect to the web portal
– Log in using:
 Username: userXX
 Password:userXX
(XX from 01 to 60)
– Get the protein sequence
– Select the appropriate parameters as written on the
explanation page
– Launch the blast program on the grid
– Wait until it is done
– Get your results

Conclusions and perspectives
Enabling Grids for E-sciencE
• The AWP is a new tool provided for the auvergrid and
biomed VO.
• The goal is to deploy web portals for all the biological
programs, coupling it with the database replication
service developed by J. Salzemann
• Next step: deploy web portals for other users
(chemistry, physics) on the Auvergne
