Report on the experience (or the proposed activity). It would be very important to mention key services which are essential for the success of your activity on the EGEE infrastructure.
The RTM has been in existence for several years, having undergone
various changes.
The current version relies on querying Resource Brokers directly
(as have all
previous versions), and relies on the BDII to provide information
about the
geographical location and resources of EGEE sites. The use of
the BDII has meant
requesting corrections in GlueSchema information for many sites,
and this is ongoing
as new sites continually join the EGEE framework.
The RTM has been in high demand for public demonstrations, and
EGEE associated
projects have also requested to be represented
(SEEGRID,EELA,EUMEDGRID,EUCHINAGRID,TRIGRID,GILDA).
Describe the added value of the Grid for the scientific/technical activity you (plan to) do on the Grid. This should include the scale of the activity and of the potential user community and the relevance for other scientific or business applications
This is a Grid monitoring tool, and so I do not know how to
answer this question.
There is no RTM without a Grid...?
Describe the scientific/technical community and the scientific/technical activity using (planning to use) the EGEE infrastructure. A high-level description is needed (neither a detailed specialist report nor a list of references).
The Real Time Monior (RTM) is both an eye catching demonstartion
and a historical job
analysis tool. By gathering information on active jobs from
Resource Brokers, the
RTM Java application provides a powerful visual way to show
public audiences the
current reality of a geographically distributed and actively
functioning EGEE Grid.
The RTM also summarises jobs as they finish, and publishes daily
summary reports. We
are also involved in the WLCG Monitoring Working Group
With a forward look to future evolution, discuss the issues you have encountered (or that you expect) in using the EGEE infrastructure. Wherever possible, point out the experience limitations (both in terms of existing services or missing functionality)
The use of the L&B API for gathering information from the
Resource Brokers would be
preferable, but so far the API is not suited to the types of
query necessary for the RTM.
Involvement in the WLCG Monitoring Working Group means we hope to
be able to provide
more information back to Site administrators in a meaningful way,
to improve the EGEE
Grid fabric reliability.
