Collaboration between Universities of Leeds, Sheffield and York
Each site has HPC resources, allows access to whole WRG
WRG e-Science Centre: Responsible for collaborative research and P-Grade deployment

Some users prefer web based access than SSH
Ease of running jobs on remote sites One access point for all resrouces.

Tested alternatives, NGS Portal, Enginframe, EASA
Needed a generic job submission system, not applications based.
Free! Well supported

P-Grade installed in VM at York Install straight forward but did need support
from developers Cut down many features to make it easier
for users / support. Configured SGE job managers Extensive testing carried out INCA testing of all three sites

Especially like the workflow editor It does what it says on the tin! Stable, run for many months at a time Not easy without detailed training Some bugs
◦ Java integration issues meaning jobs marked as ‘incomplete’, and strict dependencies on Java versions
◦ Not possible to inspect a job without downloading a zip file
◦ Deletion of a workflow leaves the old name unusable◦ Incompatible with Ubuntu’s default Java
User interface could be made more ‘friendly’ Some steps are confusing e.g. “set for grid”

SARoNGS◦ SARoNGS is a project supported by the UK
National Grid Service◦ Allows a user to create a short lived proxy based
on their institutional login via Shibboleth.
Integrated with P-Grade◦ Simple to do. Add a button on certificate page,
plus JSP code to populated the certificate download form

Some difficulties installing 2.9◦ Install now separates Condor / Java etc◦ Condor not running stably ◦ Lack of time due go to production level
NGS WMS now reached maturity◦ Hope to have integration between WMS and P-
Grade SARoNGS to handle certificates and login
