Speakers
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 accounting activity comprises the following services:
- R-GMA: The collection of accounting usage records is done through R-GMA, an
implementation of the Grid Monitoring Architecture (GMA) proposed by the Global Grid
Forum (GGF).
- Apel: Apel is a log processing application which is used to interpret gatekeeper
and batch system logs to produce accounting records.
- Accounting Enforcement Task: To ensure the “data rightness” it is required to
supervise and analyse the accounting data. Sites with problems publishing data are
contacted using the EGEE GGUS support and ticketing system.
- Accounting Portal: Accounting statistics are available through the accounting
portal for the analysis of the different grid users, VO admins and site
administrators. The APG advisory board ensures the development of the accounting
portal meets the requirements of the grid community.
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
The accounting statistics available through the Accounting Portal help the community
to understand how the grid is being used by the different VO and users. How the
resources are being distributed among the different VO and sites. How many resources
(memory, disk, cpu, etc.) are needed to perform the different scientific tasks. The
efficiency of the different jobs and the reliability of the sites. To establish SLA
and to check them. The added value obtained is an increase in efficiency of use of
the resources on the various Grids and an optimisation of resources delivered to the
various scientific communities.
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 accounting activity collects the accounting data of all sites participating in
the EGEE and WLCG infrastructures as well as from sites belonging to other grids that
are collaborating with EGEE (OSG, Nordugrid, ..).
The data are then available for use, in different views through the Accounting
Portal, by: all scientific communities using the named Grid Infrastructures; the
owners and administrators of the constituent resources, and the management of the
Grid Infrastructures.
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)
Future work:
- Storage Accounting: availability and usage of disk and tape storage.
- Adoption of more OGF Standards. The OGF Usage Record is already used. Resource
Usage Service web services interfaces for data transfer and interrogation are being
developed.
- Include information about the reliability of the infrastructure
(cancelled/failed/successful jobs) and the efficiency of the jobs/sites.
- Include information about the differences between committed (MoU), installed and
used resources.
