| The first application is of use to local (and remote) bioinformaticians who wish to run BLAST jobs against genomic and proteomic databases. This application, presented in a portal such as this has every chance of becoming a production-level application of value to the wider bioinformatics and genetics communities. The second application was developed as a demonstrator for the DyVOSE project and is unlikely to become production-level. |

This page contains details of the Shibbolized Resources to be found at [http://www.nesc.ac.uk/hub/ National e-Science Centre Hub at the University of Glasgow (UK)]. The ESP-GRID project (based at the University of Oxford) partnered with the team at NeSC at Glasgow to Shibboleth-enable their grid portal applications.
The applications use the Gridsphere portal and, previously, were accessed simply using a username/password combination that was known to the portal. The team made the access to the portal and the portlets via Shibboleth as a demonstrator.
The demonstrator shows how non-computer-specialist researchers are likely to access the power of grid computing in the future.
The portal had two main uses to researchers:
Access to [http://www.ncbi.nih.gov/BLAST/ BLAST] databases and queries via the [http://www.brc.dcs.gla.ac.uk/projects/bridges/ BRIDGES] portlet
Access to the [http://labserv.nesc.gla.ac.uk/projects/dyvose/ DyVOSE] project's text-mining demonstrator
(The first application is of use to local (and remote) bioinformaticians who wish to run BLAST jobs against genomic and proteomic databases. This application, presented in a portal such as this has every chance of becoming a production-level application of value to the wider bioinformatics and genetics communities.
The second application was developed as a demonstrator for the DyVOSE project and is unlikely to become production-level.)
The information below gives an outline of how the demonstrators operate.
We hope to have a demonstration username/password combination for you to use (very soon)
Connect to the Gridsphere portal
You can connect to the portal containing the BRIDGES and DyVOSE portlets at:
This will direct you to the [http://sdss.ac.uk/ SDSS] Shibboleth Where Are You From (WAYF) service:
The 'home organisation' to choose is the "DyVOSE" Project" (although it is hoped that it will soon be possible to use the general University of Glasgow single sign-on).
Once past that point, you should see the NeSC Gridsphere portal:

(This shows an example of Richard Sinnott being logged in)
The interface shown enables you to run a BLAST job. Some users are able to run BLAST jobs using the compute resources of the NGS (nationally). However, others are just restricted to the CONDOR pool at the University of Glasgow.
Look at the Shibboleth attributes presented
If you scroll to the bottom of the main screen, you will see the Shibboleth attributes that were passed to the portal and portlet, so that the authorisation decisions can be made.
http://users.ox.ac.uk/~markn/wikifiles/shibAtribs.png
(Again, these are attributes belonging to Richard Sinnott)
Look at the DyVOSE portlet
At the top of the portal window, you can click on "Grid Search Sort Portlet". This is the application demonstrator for the DyVOSE project. This application uses PERMIS for the authorisation decisions. You can see in the permisROLE attribute, to which student team you have been assigned. For example, Richard (see above) was assigned to both student teams and is given the status of 'Investigator' (i.e. "studentteam1;studentteam2;investigator").
Feel free to experiment with the application.
