ATLAS Tests

ATLAS jobs are sent to each UK site periodically and the results summarised. The jobs attempt to use the latest production version of the software installed at each site. Jobs are cancelled if they don't complete within 8 hours.

CE Computing Element - this denotes which CE the jobs were sent to at the site. Most sites have one CE but some have more than one that are tested separately.
Release This shows the latest version of the ATLAS software installed at the site. If this is the latest available version then it is green, if it is the previous version it is yellow and if it is older it is red.
Replica This denotes whether a replica of a test file exists at the site and if so what sort of Storage Element is is on (either dCache, DPM or CASTOR).
HW, NP and UA Hello World, New Package and User Analysis - these refer to three different tests jobs as described below. The results of the last completed job are shown. S denotes Success, F Failure, A Aborted and X Cancelled.
24 Hrs This is the average success rate over the last 24 hours.

Hello World Grid Jobs (HW)

These jobs execute a precompiled version of Athena HelloWorld that prints a customized string once per event. The correct result should be "10", the number of times this string is printed.

These jobs test that the ATLAS software is installed and the runtime works OK.

Building New Package Grid Jobs (NP)

These jobs attempt to create a new Athena package, build it and run it for 10 events. The package is a simple alogithm that just increments a counter and prints out its value at the end of the job. Once the output is returned it is scanned for this value and hence for 10 events the correct result should be "10".

Essentially the job tests that the ATLAS software is installed and (at least some of it) is functional, that CMT creates and configures the new package and that gmake works to build it. Finally it checks that the ATLAS runtime is OK.

User Analysis Grid Jobs (UA)

These jobs attempt to analyse a file of AOD data (100 Z->e+e-) that has been replicated on each site's SE. Currently the data is copied from the SE to the WN where the job is running. A new Athena package is created as in the simple job which reads the data, loops over all electron pairs and calculates the Z mass. Hence the correct result should be around 90 (GeV).

In addition to the tests in the simpler jobs, this job tests that the replica still exists on the SE, that lcg-cp can copy it to the WN, that the AOD data can be read from StoreGate and that a sensible Z mass is calculated.
