1. CernVM-FS Operations in the CERN IT Storage Group
Dan van der Ster (CERN)
06/06/2016, 16:20

This talk will present the status and plans of the CERN IT's CVMFS Operations Service, recently reassigned to our IT Storage Group. The first part of the talk will outline the architecture of the stratum zero, CERN stratum one, local squids; the notable feature of our service is that during 2015 is has been (almost) entirely moved to CERN's OpenStack infrastructure, making extensive use of...

14. Introduction to Mesos and the Datacenter Operating System (DC/OS)
Dr Artem Harutyunyan (Mesosphere)
06/06/2016, 17:15

Existing research has shown the benefits of running multi-level schedulers, either for single node parallel computation or multi-node distributed computation. Apache Mesos is a 2-level distributed scheduling system that has been used in organizations such as Twitter, PayPal, and Apple.

In this talk we'll describe the 2-level Mesos architecture in detail. We'll also discuss Mesos features that...
13. Virtualizing High Performance Computing Workloads
Josh Simons (VMware)
07/06/2016, 09:00

A short presentation on how and why HPC users are moving beyond public cloud for HPC workloads, including a discussion of achievable performance for both throughput and (briefly) MPI applications. We will also touch on compute accelerators, file system access, and containers, and provide some performance tuning tips for virtualizing HPC applications with high performance.

**About the...

George Lestaris (Pivotal)
07/06/2016, 11:45

Cloud foundry is a PaaS that facilitates deployment and scale of web applications. It aims at providing a good user experience while ensuring that deployed application follow the best practices. Additionally, It provides a full set of features that enable debugging and monitoring of production systems. However, Docker is disrupting more traditional PaaS by making containers a prominent term in...

2. CVMFS for Data Federations
Brian Paul Bockelman (University of Nebraska (US))
07/06/2016, 14:20

A data federation is a cooperating set of storage resources transparently accessible across a wide area network via a common namespace. These are often implemented through a redirector hierarchy - clients query a centralized endpoint for a given file; this redirector locates an available storage resource, then redirects the client to the remote resource.

Data federations are an...

0. Using CernVM-FS to deploy Euclid processing S/W on Computing Centres
Mr Mark Holliman (ROE), Mr Maurice Poncet (CNES)

CernVM-FS is being tested by the System Team of the Science Ground Segment (SGS) within the Euclid Project (http://www.euclid-ec.org/) as the primary execution environment and software distribution tool for processing mission data. In particular, CernVM-FS is viewed as a possible solution to the problem of providing a homogenous execution environment across heterogeneous computing resources...
