6. 1 Release PM 9 Job and resource required description:
using class-ads language.
a possible high level interface based on XML will be investigated.
first release of command line tool for job management (to submit, cancel, monitor jobs).
job policy and admission control.
policies on resource usage based on user and user community identity.

7. 1 Release PM 9
available resource selection using code migration paradigm. This selection will take into account:
available CPU in different farms spread in different sites.
location of input data.
cost of executable migration.
available resources (disk space) for output data.
first release of accounting and bookkeeping services:
monitoring of job status about processed data,
output data produced, processing evaluation.
The globus GRAM protocol is the uniform interface to the local resources. The local resources are "cluster" of nodes, mainly PCs,managed by the PBS, LSF, Condor etc. software.The basic information system for this release is the Grid Information Service by the Globus project.

8. 2 Release PM 21
Improvement of the first release also for high performance jobs taking into account:
job monitoring data
resources (Computing, Storage, Network) monitoring data
performance prediction
cost of data migration
fault tolerance
The scheduling activity will also consider co-allocation of multiple resources, cost of data movement/replication,remote data access.
Improvement of the high level job description interface and user services interface.
Evaluation and adoption of a proper security framework for allocation and authentication of resources usage.

9. 3 Release PM 33 Exploitation of data/task parallelism
Advance reservation of resources
Optimal scheduling or rescheduling using performance monitoring tools
