Description
As modern High Energy Physics (HEP) experiments require more
distributed computing power to fulfill their demands, the need for
an efficient distributed online services for control, configuration
and monitoring in such experiments becomes increasingly important.
This paper describes the experience of using standard Common Object
Request Broker Architecture (CORBA) middleware for providing a high
performance and scalable software, which will be used for the online
control, configuration and monitoring in the ATLAS Data Acquisition
(DAQ) system. It also presents the experience, which was gained from
using several CORBA implementations and replacing one CORBA broker
with another.
Finally the paper introduces results of the large scale tests, which
have been done on the cluster of more then 300 nodes, demonstrating
the performance and scalability of the ATLAS DAQ online services.
These results show that the CORBA standard is truly appropriate for
the highly efficient online distributed computing in the area of
modern HEP experiments.
