A New Era for Central Processing and Production in CMS
The goal for CMS computing is to maximise the throughput of simulated event generation while also processing event data generated by the detector as quickly and reliably as possible. To maintain thisExpand

Internship: Conventional Wisdom, Models & Recommendations
Internship has been attracting considerable attention for a number of years and, yet, has rarely been the subject of any sustained, serious research. The research that informed the production of theExpand

Using the CMS High Level Trigger as a Cloud Resource
The CMS High Level Trigger is a compute farm of more than 10,000 cores. During data taking this resource is heavily used and is an integral part of the experiment's triggering system. However,Expand

Quantifying XRootD Scalability and Overheads
TLDR
We look at the overhead and scalability of the XRootD software system, and the overhead of the infrastructure needed to support remote access to data. Expand

The Diverse use of Clouds by CMS
The resources CMS is using are increasingly being offered as clouds. In Run 2 of the LHC the majority of CMS CERN resources, both in Meyrin and at the Wigner Computing Centre, will be presented asExpand

Using container orchestration to improve service management at the RAL Tier-1
TLDR
In recent years container orchestration has been emerging as a means of gaining many potential benefits compared to a traditional static infrastructure, such as increased utilisation through multi-tenancy, improved availability due to self-healing, and the ability to handle changing loads due to elasticity and auto-scaling.

CMS distributed computing workflow experience
TLDR
The vast majority of the CMS Computing capacity, which is organized in a tiered hierarchy, is located away from CERN. Expand

The relationship between j × B and ∇·Pe in the magnetotail plasma sheet: Cluster observations
[1] In this paper we report an extension to Henderson et al.'s (2006) case study, in which we investigate the generality of the anticorrelation between the ∇·e and j × B terms in Ohm's law observedExpand

An Analysis of Data Access Methods within WLCG
TLDR
With WLCG experiments making increasing use of the xrootd framework and changes to the tiered model away from the classic MONARC architecture to a mesh, new options for accessing data for analysis have become possible. Expand
