Abstract
In this paper we showcase the support in Open Science Grid (OSG) of Midscale collaborations, the region of computing and storage scale where multi-institutional researchers collaborate to execute their science workflows on the grid without having dedicated technical support teams of their own. Collaboration Services enables such collaborations to take advantage of the distributed resources of the Open Science Grid by facilitating access to submission hosts, the deployment of their applications and supporting their data management requirements. Distributed computing software adopted from large scale collaborations, such as CVMFS, Rucio, xCache lower the barrier of intermediate scale research to integrate with existing infrastructure.
Highlights
In Open Science Grid (OSG) [1][2] we support science at all scales
The experiment specific workload of large scale science projects requires significant software and computing technical teams. Such teams are responsible for the development, validation, and deployment of the computational workload and data management systems and coordinate closely with OSG technical teams in integration and operationalization across the grid sites
CERN Virtual Machine File System (CVMFS) [3] is a POSIX-like read-only file system in userspace (FUSE) that delivers a portable solution in making files available on-demand to jobs running on a distributed infrastructure
Summary
In Open Science Grid (OSG) [1][2] we support science at all scales. The experiment specific workload of large scale science projects requires significant software and computing technical teams. On the other end of the scale are the individual researchers across multiple fields, who access the grid opportunistically for their job submissions Their workflows are often supported by OSG research facilitators with expertise in high-throughput computing. The limited availability of technical teams embedded within the Midscale collaborations presents challenges for support services The latter will need to provision a distributed computing environment with easy access to software, support of containerized solutions, and enable reliable distribution of data and automation. In this proceedings paper, we list a few distributed cyberinfrastructure solutions that were adopted by OSG from large scale projects, for example, the LHC, and outline their implementation in specific midscale collaborations
