ATLAS is one of the four experiments under construction along Large Hadron Collider (LHC) ring at CERN. The LHC will produce interactions a center-of-mass energy equal to radics = 14 TeV with frequency 40 MHz. detector consists more than 140 million electronic channels. challenging experimental environment and extreme complexity impose necessity common, scalable, distributed monitoring framework, which can be tuned for optimal use by different sub-detectors various levels data flow. This...
This paper presents the experience of using a CORBA-based communication package for inter-component control and status information in ATLAS prototype DAQ project. A public domain package, called Inter-Language Unification (ILU) has been used to implement between components local area network (LAN) heterogeneous computers. The selection CORBA standard ILU implementation are judged against requirements system. An overview is included. Several system have designed implemented CORBA/ILU which...
The ATLAS combined test beam in the second half of 2004 saw first deployment High-Level Trigger (HLT). next steps are on pre-series farms experimental area during 2005, commissioning and cosmics tests with full detector 2006 collisions 2007. This paper reviews experience gained beam, describes current status discusses further enhancements to be made. We address issues related dataflow, integration selection algorithms, testing, software distribution, installation improvements.
The authors discuss the CERN Host Interface Project, which aims to provide modular interfaces between Digital Equipment Corporation's VAX series computers and two popular high-energy physics buses, VMEbus FASTBUS. These user-programmable contain a powerful central processing unit, large data memories, ports that allow user configure interface for required host computer target bus. software support optical connection are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The CERN Host Interface (CHI) is a family of interfaces to interconnect Fastbus, VMEbus, and external host computers. Fastbus interface consists processor board (CHI-P) host-specific I/O ports allowing connection using fast parallel or serial interfaces. For efficiency in data acquisition chain, the CHI-P contains 1-MB triple-port memory which allows concurrent access by (as master slave), link, 4.5 MIPS onboard processor. processor, an MC68030 with floating point coprocessor, also has 1 Mb...
The high-performance parallel interface (HIPPI) is an ANSI standard, using a minimal protocol and providing 100 Mbyte/s transfers over distances up to 25 m. A brief technical introduction the HIPPI given, followed by examples of planned applications in high-energy physics experiments including developments involving CERN: detector emulator, RISC-processor-based VME connection, long-distance fiber optics testbox. Equipment this standard offered growing number computer manufacturers....

The ESONE/IEEE/NIM standard CAMAC subroutines have been implemented on a variety of on-line computer systems at CERN. Computers range from 8-bit microprocessors to 32-bit minis (M6800, HP/1000, PDPl1, NORD, VAX) and interfaces include dedicated crate controllers, branch drivers system configurations. subroutine package is now in widespread use CERN, for example large physics experiments where comprise several types computers interfaces. implementation will be described with emphasis areas...
The DAQ group of the future ATLAS experiment has developed a prototype system based on trigger/DAQ architecture described in Technical Proposal to support studies full functionality, as well available hardware and software technologies. One sub-system this is back-end which encompasses needed configure, control monitor DAQ, but excludes processing transportation physics data. consists number components including run control, configuration databases message reporting system. been using...
The access of the ATLAS Trigger and Data Acquisition (TDAQ) system to Conditions Databases sets strong reliability performance requirements on database storage infrastructures. Several applications were developed support integration with online services in TDAQ, including interface Information Services (IS) TDAQ Configuration Databases.
