Collaboration is undertaking design studies for multiple accelerator
projects with emphasis on proton-proton and electron-positron high-energy
frontier machines. From the beginning of the collaboration, the development
of a software stack with common and interchangeable packages plays an
important role in simulation,... -

Dave Dykstra (Fermi National Accelerator Lab. (US))03/06/2019, 16:00
CVMFS is primarily used on the grid for distributing released experiment code, and it is expected that only a small number of people in each experiment manage that code. Fermilab has implemented a system for publishing temporary user analysis code in CVMFS, with repositories that are shared by many people and a server API that accepts tarballs from users in multiple experiments. Updates are...

The Pacific Research Platform (PRP) is operating a Kubernetes cluster that manages over 2.5k CPU cores and 250 GPUs. The compute nodes are distributed over several locations, mostly in California, all connected with high speed networking of 10Gbps or higher.
In order to support OSG users, we were in need of providing CVMFS support in the Kubernetes cluster. Since user containers run...

The Storage group of the CERN IT department operates the CVMFS release managers for repositories hosted at CERN (also known as stratum zeros), the CERN replica servers (stratum ones), and the local squid caches. This talk describes the current architecture of the CVMFS service at CERN and reports on the introduction of S3 as the storage backend for stratum zeros, the upgrade of selected...

Johannes Martin Heinz03/06/2019, 17:00
This talk outlines the usage of the CernVM file system in the EP-SFT-SPI section at CERN. Its task is to distribute and continuously update a software stack (called LCG Releases) that is used by ATLAS, LHCb, SWAN and several more.
The stack contains HEP specific software as well as external packages. There are usually two major releases per year as well as nightly builds with the latest...

Harris Hancock (Cloudflare)04/06/2019, 09:00
Cloudflare Workers is a serverless computing platform optimized to minimize latency to end users. Cloudflare runs every guest function in each server of its network's 175 points of presence, meaning code runs as close to the end user as possible, and is not confined to geographic regions. This requires overcoming a scalability challenge faced by container-based platforms: how to reduce each...

The Jülich Supercomputing Centre (JSC) operates a large-scale network-, data- and compute-infrastructure for scientific research covering a broad spectrum of use cases from scalability-focused large-scale simulations to community-specific services with high-throughput requirements. In this talk we will discuss the design of JSC’s facility addressing such different use cases though a mixture of...

Michael Bauer (Sylabs)04/06/2019, 11:00
The Singularity container runtime has become widely adopted as the de facto standard container platform for HPC workloads. At the beginning of 2018, Sylabs was founded to further HPC innovation by driving Singularity development. This talk will explore some of the ways in which the Singularity community and Sylabs are helping to solve problems in the HPC space, with a focus on the efforts of...

Giuseppe Scrivano (Red Hat)04/06/2019, 17:00
During my talk, I will show how it is possible to run OCI containers with Podman without requiring root privileges on the host.
In the second part of the talk, I'll focus on how we use fuse-overlayfs to replace the kernel overlay file system implementation, and the fuse-overlayfs built-in shifts-like capabilities.
