General
What is ADA?
ADA (ATLAS Distributed Analysis) is an project to enable ATLAS users
to easily do distributed analysis. It combines many of systems that
have been developed within ATLAS including data management, production,
GANGA and DIAL. For more information, see the
ADA home page.
Where do I find the ADA user guide?
There is no user guide for ADA but the latest DIAL release page
provides links to most of what is available. To find this page,
please follow the link from the
ADA home page.

Jobs
How do I submit a job using ADA?
The "Getting started" section of the
user guide provides links for
running demos and examples of serious analysis using the
root client. The user guide also provides links to instructions
for using PyDIAL or the job submission GUI.
The service where the job was submitted may be queried for
the job status using the root interface, PyDIAL interface or
the GUI. See the user guide.
See the section on failed jobs in the user guide.
The scheduler provides a method to kill a job and all
its subjobs, e.g. from root: msch.kill(jid).
Analysis services
Which analysis service should I use?
See the
service monitor page
for a complete list of available services and the status for each.
At present the most reliable service is the LSF service at BNL:
adial01.usatlas.bnl.gov:20011. If you do not specify the service, your client should
default to a sensible one for your installation.
Data
What data are available?
At present most of the Rome AOD's are available for analysis with ADA.
Query the DSC (Dataset Selection Catalog) with "level='TOP'" for a
complete list of datasets intended for user analysis. The user guide
shows how to make this query using the root or web interfaces.
AT present the data location in encoded in the dataset name. The files for
dataset names ending in .AOD are available at both CERN and BNL. The files for
those ending in .AOD-bnl are available at BNL.
