The data acquisition backbone core DABC is designed for FAIR detector tests, readout components test, data flow investigations, and DAQ controls. All kinds of data channels (front-end systems) are connected by plug-ins into functional components of DABC like data input, combiner, scheduler, event builder, analysis and storage. On the other hand, the current GSI DAQ system MBS with its huge installed hardware base (about 100 installed, 50% outside GSI) must be integrated in any new DAQ concept. After detailed simulations now real tests (on InfiniBand clusters) of event building over networks had been performed. Several software packages (uDAPL, OpenFabric IB Verbs, MPI2) have been used to measure the performance of InfiniBand. One can achieve about 80% of the bidirectional nominal IB bandwidth of 1 GByte/s. To achieve real reliable performance with IB one needs the optional real time extensions of the latest Linux kernel 2.6.21. Some infrastructure components of the XDAQ package developed for the CMS experiment have been evaluated for DABC. The development of key components is supported by the FutureDAQ project of the European Union (FP6 I3HP JRA1).","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121505867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose to extend the SVT use, now mostly focused on B-physics, to high-PT physics as a tracker in the forward/backward region. The upgraded SVT structure is easily improved working on firmware, or connecting the existing general purpose FPGA-based SVT boards, named Pulsars, with other Pulsars in a lego-structure. In particular, SVT can easily extend the prompt-lepton acceptance providing silicon-only tracks where the drift-chamber coverage is poor or missing (pseudorapidity larger than 1). Since prompt-leptons from high-PT events do not require precise impact parameter measurement, we don't need to measure these tracks with the maximum silicon detector resolution. We enlarge the use of the AM, to detect tracks above a defined PT threshold. We propose a bypass that brings the new thin roads found by AM, directly to the level-2 CPUs. While the slower full-resolution path (TF) will have to digest the normal AM road production, four new Pulsars will deliver new roads from AM to L2-CPU. All the hardware exists, needs only to be assembled. We present the bypass architecture, the forward-track quality and their possible use in Higgs triggers. The system timing is estimated from simulation on real data and measurements on test stand.","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127619771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This presentation is the result of a study aiming at the identification of the best software architecture suitable for the data acquisition, detector control and data analysis for all detector types which are being developed presently. The software has to be appropriate for the test and production phases which means for raw data acquisition, analysis and visualization. In addition the software has to work on Linux and Windows and the Root Framework shall be used. To achieve these goals a layered design with well defined tasks for each layer has been implemented. Moreover, almost every single task could be easily moved from software to the detector front-end FPGAs and vice versa. Every task is connected with its data type(-s); so different modules (software or hardware) can easily be separated and moved from/to the software. The whole design is done using standard C++ language together with Boost libraries and Qt for GUI in such a way that the software should compile and work on almost any platform.","PeriodicalId":217483,"journal":{"name":"2007 15th IEEE-NPSS Real-Time Conference","volume":"55 33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121857403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
