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).
This work is a part of DEGREE project and is focused on
requirements of Earth
Science applications on job management. Earth Science community
covers a
wide range of applications from space industry to meteorology,
hydrology,
seismology, geology and environmental applications. The community
consists of
research institutes, European organizations and industries, and
actively
participate on EGEE I and EGEE II projects.
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 discussion would be useful for detailing requirements of ES
applications:
- Fault tolerance: guaranty that the job will be sucessfully
executed. If a fault
occurs, more information about the reasons and status of job at
the moment
are required for debugging
- Real-time and near-realtime job executions for some groups of
interactive and
critical applications
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 work in WP3 in DEGREE project is focused on analyzing
requirements of ES
applications on job management and control, identifying the missing
functionalities of available middleware and tools and preparing
test cases for
assessing usability of the middleware and tools from the view of ES
applications. It will deliver the requirements on job management
of the wide
application range in Earth Science community to middleware
developers,
interact with them using concrete use cases from applications,
provides test
suites for testing functionality of the middleware according to
the requirements
and motivate the research and developments in Grid middleware
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 requirements of job management and control in Earth Science
communities
can be classified into following areas: workflow management,
fault tolerance,
near-realtime job execution and job monitoring.
For workflow management, although a built-in workflow manager in
gLite and
several independent workflow managers exist, ES still needs an
upper layer
defined as an ‘intelligent assistant’ interface, including knowledge
representation and reasoning tools, to facilitate scientific
workflows for complex
applications. Fault tolerance and near-realtime job execution are
very important
for several applications in Earth Science. ES application also
require more detail
and up-to-date information about job running on the Grid.
