Many-core experience with HEP software at CERN openlab

The future of commodity computing and many-core versus the interests of HEP software

As the mainstream computing world has shifted from multi-core to many-core platforms, the situation for software developers has changed as well. With the numerous hardware and software options available, choices balancing programmability and performance are becoming a significant challenge. The expanding multiplicative dimensions of performance offer a growing number of possibilities that need ...

Many-core applications to online track reconstruction in HEP experiments

Interest in parallel architectures applied to real time selections is growing in High Energy Physics (HEP) experiments. In this paper we describe performance measurements of Graphic Processing Units (GPUs) and Intel Many Integrated Core architecture (MIC) when applied to a typical HEP online task: the selection of events based on the trajectories of charged particles. We use as benchmark a scal...

Automated Purification Software for Agilent OpenLAB CDS

Agilent 1260 Infinity LC and LC/MS purification systems offer flexible and easy‐to‐use solutions for purification of microgram to gram quantities of samples, with maximum levels of recovery and purity. Using combined or dedicated analytical and preparative‐scale systems configured to meet the throughput demands of your laboratory, the Agilent Automated Purification Software automates the transf...

CERN-TH/2001-215 hep-ph/0108069

We study in this paper the production, in hadronic collisions, of final states with W gauge bosons, heavy quark pairs and n extra jets (with n up to 4). The complete partonic tree-level QCD matrix elements are evaluated using the ALPHA algorithm, and the events generated at the parton level are then evolved through the QCD shower and eventually hadronised using the coherent shower evolution pro...
