The CMS regional calorimeter trigger system detects signatures of electrons/photons,taus,jets,and missing and total transverse energy in a deadtinmess pipelined architecture .This system receives 7000 calorimeter treg...
Industry experts are increasingly focusing on team productivity on team productivity as the key to success,the base of the team effort is the four-fold structure of software in terms of logical organisation,physical o...
The CMS experiment at the CERN LHC collider is producing large amounts of simulated data in order to provide an adequate statistic for the Trigger System design.These productions are performed in a distributed environ...
The CMS Collaboration of 2000 scientists involves 150 institutions from 31 nations spread all over the world.CMS software system integration and release management is performed at CERN.Code management is based on CVS,...
Powerful mainstream computing equipment and the advent of affordable multi-Gigabit communication technology allow us to tackle data acquisition problems with clusters of inexpensive computers.Such networks typically i...
The data acquisition system for the CMS experiment at the Large Hadron Collider (LHC) will require a large and high performance event building network.Several architectures and swithch technologies are currently being...
The CMS IGUANA project has implemented an open analysis architecture that enables the creation of an integrated analysis environment.In this "analysis desktop" environment a physicist is able to perform most analysis-...
The multi-tiered architecture of the highly-distributed CMS computing systems necessitates a flexible data distribution and analysis environment.We describe a prototype analysis environment which functions efficiently...
The need for writing software packages that do not depend explicitly on the server code,and do not need to be modified,when new server interfaces arise,lead to the development of the hidden adapter pattern.We will sho...
New experiments including those at the LHC will require analysis of very large datasets which are best handled with distributed computation.We present the design and development of a prototype framework using Java and...
