Toolchain for Online Modeling of the LHC

Xavier Buffat, Massimo Giovannozzi

The control of high intensity beams in a high energy, su- perconducting machine with complex optics like the CERN Large Hadron Collider (LHC) is challenging not only from the design aspect but also for operation towards physics production. To support the L ...

A Hybrid Peer-to-Peer and Grid Job Scheduling System for Teaming Up Desktop Resources with Computer Clusters to Perform Turbulence Simulations

Tobias Schneider

Simulating turbulence in fluids is a fascinating part of physics which requires a high amount of computational power. Since for transitional Reynolds numbers each simulation run can be performed on a single contemporary CPU, turbulence studies are ideally ...

Continuous Bytecode Instruction Counting for CPU Consumption Estimation

Andrea Camesi

As an execution platform, the Java Virtual Machine (JVM) provides many benefits in terms of portability and security. However, this advantage turns into an obstacle when it comes to determining the computing resources (CPU, memory) a program will require t ...
