Ferrara Resources

Ferrara is involved in INFN-GRID (Grid.it) project. The aim of INFN-GRID is the realization of a production grid. The site configuration is almost the same as EDG. INFN-GRID 1.0.0 (based on LCG 1.0.1, Red Hat 7.3) installed in:

1 Computing Element 1 Storage Element 1 User Interface 6 Worker Nodes

Also installed a federation of Objy DB and a lockserver on separate SUN machines.

Upgrading to INFN-GRID 1.1.1 in the next 3 days.


Software Installation

The official release of INFN-GRID comes with Moose rpm, including also the configuration files for the BaBar VO.

Using BaBar release 12.4.0 + tags for ROOT output (building a rpm for release 14.1.1a).

So, each italian site of the INFN-GRID project has Moose installed by default.

The INFN-GRID Resource Broker is located at CNAF, at the moment it sees only italian resources.

We would like to set up a Resource Broker for BaBar in Ferrara, in order to registrate not only italian resources.


Tests

Tests performed on EDG 1.4.x Tests performed on EDG 2.0.x First tests performed on italian sites on

INFN-GRID 1.0.0 Tests will be performed on INFN-GRID

1.1.1 in the next days.


First results

Some hundreds of jobs submitted to all italian sites (Ferrara, Napoli, Bologna, Legnaro, Bari, Padova, Trieste, Milano) in different times of the day for ~1 week.

Jobs submitted to Ferrara had ~95% of success. Jobs submitted to other italian resources had ~60% of

success. Main failure causes have been

Problems of the Resource Broker (due to Globus services: ~7%) Problems in remote access to our Objy DB (due to simultaneous

accesses and network overload: ~33%)


Network load during the tests INFN - Ferrara

Max In/s: 9063.4 kb/s (75.5%) Average In/s: 1661.1 kb/s (13.8%)Current In/s: 551.4 kb/s (4.6%)Max Out/s: 8531.6 kb/s (71.1%) Average Out/s: 919.4 kb/s (7.7%) Current Out/s: 2142.2 kb/s (17.9%)
