ATLAS DDM integration in ARC

Arc Spaces , Motivic Integration

The concept ofmotivic integrationwas invented by Kontsevich to show that birationally equivalent Calabi-Yau manifolds have the same Hodge numbers. He constructed a certain measure on the arc space of an algebraic variety, the motivic measure, with the subtle and crucial property that it takes values not in R, but in the Grothendieck ring of algebraic varieties. A whole theory on this subject wa...

Ddm { a Cache - Only

The long latencies introduced by remote accesses in a large multiprocessor can be hidden by caching. Caching also decreases the network load. We introduce a new class of architectures called Cache Only Memory Archi-tectures (COMA). These architectures provide the programming paradigm of the shared-memory architectures, but have no physically shared memory; instead, the caches attached to the pr...

Interact-DDM: A Solution for the Integration of Domestic Devices on Network Management Platforms

This paper presents Interact-DDM, a solution that integrates domestic devices with traditional computer networks. The architecture proposal is based on TCP/IP network management standards: SNMP protocol and Management Information Bases, MIB. The centralized management operation has been enhanced with additional capabilities integrated on the agents. The design has been performed permitting a ve...

ATLAS TDAQ System Integration and Commissioning

The ATLAS detector will be exposed to proton proton collisions at a center of mass energy of 14 TeV with the bunch crossing rate of 40 MHz. A three-level trigger system has been designed to reduce this rate down to the level at which only interesting events are fully reconstructed. The level 1 trigger reduces the rate down to 75 kHz via custom-built electronics. The Region of Interest Builder d...
