To Be Defined
The DAQ group of the future ATLAS experiment has developed a prototype
system based on the Trigger/DAQ architecture described in the ATLAS
Technical Proposal to support studies of the full system
functionality, architecture as well as available hardware and software
technologies.
One sub-system of this prototype is the back-end which encompasses the
software needed to configure, control and monitor the DAQ, but excludes
the processing and transportation of physics data.
The back-end consists of a number of components including run control,
configuration databases and message reporting system. The software has
been developed using standard, external software technologies such as OO
databases and CORBA. It has been ported to several C++ compilers and
operating systems including Solaris, Linux, WNT and LynxOS.
Performance and scalability tests have been made for individual
components and, more recently, for the complete back-end sub-system.
Such tests include a configuration comparable to that required for the
final ATLAS system.
This paper gives an overview of the back-end software, its performance,
scalability, current status and future developments.
