Abstract

This paper presents the experience in providing CERN users with direct online access to their EOS/CERNBox-powered user storage from Windows. In production for about 15 months, a High-Available Samba cluster is regularly used by a significant fraction of the CERN user base, following the migration of their central home folders from Microsoft DFS in the context of CERN’s strategy to move to open source solutions. We describe the configuration of the cluster, which is based on standard components: the EOS-backed CERNBox storage is mounted via FUSE, and an additional mount provided by CephFS is used to share the cluster’s state. Further, we describe some typical shortcomings of such a setup and how they were tackled. Finally, we show how such an additional access method fits in the bigger picture, where the storage is seamlessly accessed by user jobs, sync clients, FUSE/Samba mounts as well as the web UI, whilst aiming at a consistent view and user experience.

Abstract

CERNBox is the CERN cloud storage hub for more than 25,000 users at CERN. It allows synchronising and sharing files on all major desktop and mobile platforms (Linux, Windows, MacOSX, Android, iOS) providing universal, ubiquitous, online- and offline access to any data stored in the CERN EOS infrastructure. CERNBox also provides integration with other CERN services for big science: visualisation tools, interactive data analysis and real-time collaborative editing. Over the last two years, CERNBox has evolved from a pure cloud sync and share platform into a collaborative service, to support new applications such as DrawIO for diagrams and organigrams sketching, OnlyOffice and Collabora Online for documents editing, and DXHTML Gantt for project management, as alternatives to traditional desktop applications. Moving to open source applications has the advantage to reduce licensing costs and enables easier integration within the CERN infrastructure. This move from commercial software to open source solutions is part of the MALT project, led by the IT department at CERN to reduce the dependencies on commercial solutions. As part of the MALT project, CERNBox is the chosen solution to replace Home directories of the Windows DFS file system. Access to storage from Windows managed devices for end-users is largely covered by synchronization clients. However, online access using standard CIFS/SMB protocol is required for shared use-cases, such as central login services (Terminal Services) and visitor desktop computers. We present recent work to introduce a set of Samba gateways running in High Availability cluster mode to enable direct access to the CERNBox backend storage (EOS).

Abstract

The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage requirements: the physics data generated by LHC and non-LHC experiments; object and file storage for infrastructure services; block storage for the CERN cloud system; filesystems for general use and specialized HPC clusters; content distribution filesystem for software distribution and condition databases; and sync&share cloud storage for end-user files. The total integrated capacity of these systems exceeds 0.6 Exabyte. Large-scale experiment data taking has been supported by EOS and CASTOR for the last 10+ years. Particular highlights for 2018 include the special HeavyIon run which was the last part of the LHC Run2 Programme: the IT storage systems sustained over 10GB/s to flawlessly collect and archive more than 13 PB of data in a single month. While the tape archival continues to be handled by CASTOR, the effort to migrate the current experiment workflows to the new CERN Tape Archive system (CTA) is underway. Ceph infrastructure has operated for more than 5 years to provide block storage to CERN IT private OpenStack cloud, a shared filesystem (CephFS) to HPC clusters and NFS storage to replace commercial Filers. S3 service was introduced in 2018, following increased user requirements for S3-compatible object storage from physics experiments and IT use-cases. Since its introduction in 2014N, CERNBox has become a ubiquitous cloud storage interface for all CERN user groups: physicists, engineers and administration. CERNBox provides easy access to multi-petabyte data stores from a multitude of mobile and desktop devices and all mainstream, modern operating systems (Linux, Windows, macOS, Android, iOS). CERNBox provides synchronized storage for end-user’s devices as well as easy sharing for individual users and e-groups. CERNBox has also become a storage platform to host online applications to process the data such as SWAN (Service for Web-based Analysis) as well as file editors such as Collabora Online, Only Office, Draw.IO and more. An increasing number of online applications in the Windows infrastructure uses CIFS/SMB access to CERNBox files. CVMFS provides software repositories for all experiments across the WLCG infrastructure and has recently been optimized to efficiently handle nightlybuilds. While AFS continues to provide general-purpose filesystem for internal CERN users, especially as $HOME login area on central computing infrastructure, the migration of project and web spaces has significantly advanced. In this paper, we report on the experiences from the last year of LHC RUN2 data taking and evolution of our services in the past year.. We will highlight upcoming changes and future improvements and challenges.

Abstract

The CERN IT Storage group operates multiple distributed storage systems and is responsible for the support of the infrastructure to accommodate all CERN storage requirements, from the physics data generated by LHC and non-LHC experiments to the personnel users' files. EOS is now the key component of the CERN Storage strategy. It allows to operate at high incoming throughput for experiment data-taking while running concurrent complex production work-loads. This high-performance distributed storage provides now more than 250PB of raw disks and it is the key component behind the success of CERNBox, the CERN cloud synchronisation service which allows syncing and sharing files on all major mobile and desktop platforms to provide offline availability to any data stored in the EOS infrastructure. CERNBox recorded an exponential growth in the last couple of year in terms of files and data stored thanks to its increasing popularity inside CERN users community and thanks to its integration with a multitude of other CERN services (Batch, SWAN, Microsoft Office). In parallel CASTOR is being simplified and transitioning from an HSM into an archival system, focusing mainly in the long-term data recording of the primary data from the detectors, preparing the road to the next-generation tape archival system, CTA. The storage services at CERN cover as well the needs of the rest of our community: Ceph as data back-end for the CERN OpenStack infrastructure, NFS services and S3 functionality; AFS for legacy home directory filesystem services and its ongoing phase-out and CVMFS for software distribution. In this paper we will summarise our experience in supporting all our distributed storage system and the ongoing work in evolving our infrastructure, testing very-dense storage building block (nodes with more than 1PB of raw space) for the challenges waiting ahead.

Abstract

CERNBox is the CERN cloud storage hub. It allows synchronizing and sharing files on all major desktop and mobile platforms (Linux, Windows, MacOSX, Android, iOS) aiming to provide universal access and offline availability to any data stored in the CERN EOS infrastructure. With more than 16000 users registered in the system, CERNBox has responded to the high demand in our diverse community to an easily and accessible cloud storage solution that also provides integration with other CERN services for big science: visualization tools, interactive data analysis and real-time collaborative editing. Collaborative authoring of documents is now becoming standard practice with public cloud services, and within CERNBox we are looking into several options: from the collaborative editing of shared office documents with different solutions (Microsoft, OnlyOffice, Collabora) to integrating mark-down as well as LaTeX editors, to exploring the evolution of Jupyter Notebooks towards collaborative editing, where the latter leverages on the existing SWAN Physics analysis service. We report on our experience managing this technology and applicable use-cases, also in a broader scientific and research context and its future evolution with highlights on the current development status and future road map. In particular we will highlight the future move to an architecture based on micro services to easily adapt and evolve the service to the technology and usage evolution, notably to unify CERN home directory services.

Abstract

This document presents the state of work in the WP4 of the CS3MESH4EOSC project on integrating user-level applications and usage scenarios within the ScienceMesh federation. The CS3MESH4EOSC consortium is building a federated mesh of sync & share systems (EFSS) and applications focused on scientific and research use-cases, referred to as ScienceMesh. The Interoperability Platform (IOP) worked out in WP3 provides the technical basis for the federation, ensuring compatibility across sync & share products, enabling data flow and user information exchange as well as implementing communication for application workflows. The partner-provided deployments of sync & share systems at federated sites provide the testing and pre-production environments for the federation. Finally, management procedures and tools developed by WP2 constitute the operational basis for the federation. Within WP4, a set of user-level applications is being developed with the aim of being embedded into this federated mesh of sync & share systems. This work is organized in four application-related design, development and testing tasks (T4.1-T4.4) as well as two auxiliary tasks (T4.5-T4.6). This deliverable provides the summary of the work within WP4 related to the integration of the flagship applications identified for the ScienceMesh. It provides an overview of the state of the demonstrators prepared within the first 18 months of the Project. It also summarizes the status of work in the auxiliary tasks dedicated to ensuring that requirements and other information flow among WP4 and WP3, WP4 and WP2, while analysing the future sustainability of those Project results.

Abstract

Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade. ©2019

Abstract

Storage management is one of the most important enabling technologies for large-scale scientific investigations. Having to deal with multiple heterogeneous storage and file systems is one of the major bottlenecks in managing, replicating, and accessing files in distributed environments. Storage Resource Managers (SRMs), named after their web services control protocol, provide the technology needed to manage the rapidly growing distributed data volumes, as a result of faster and larger computational facilities. SRMs are Grid storage services providing interfaces to storage resources, as well as advanced functionality such as dynamic space allocation and file management on shared storage systems. They call on transport services to bring files into their space transparently and provide effective sharing of files. SRMs are based on a common specification that emerged over time and evolved into an international collaboration. This approach of an open specification that can be used by various institutions to adapt to their own storage systems has proven to be a remarkable success -- the challenge has been to provide a consistent homogeneous interface to the Grid, while allowing sites to have diverse infrastructures. In particular, supporting optional features while preserving interoperability is one of the main challenges we describe in this paper. We also describe using SRM in a large international High Energy Physics collaboration, called WLCG, to prepare to handle the large volume of data expected when the Large Hadron Collider (LHC) goes online at CERN. This intense collaboration led to refinements and additional functionality in the SRM specification, and the development of multiple interoperating implementations of SRM for various complex multi-component storage systems.

Abstract

The main goal of the presented research is to investigate Peer-to-Peer architectures and to leverage distributed services to support networked autonomous systems. The research work focuses on development and demonstration of technologies suitable for providing autonomy and flexibility in the context of distributed network management and distributed data acquisition. A network management system enables the network administrator to monitor a computer network and properly handle any failure that can arise within the network. An online data acquisition (DAQ) system for high-energy physics experiments has to collect, combine, filter, and store for later analysis a huge amount of data, describing subatomic particles collision events. Both domains have tight constraints which are discussed and tackled in this work. New emerging paradigms have been investigated to design novel middleware architectures for such distributed systems, particularly the Active Networks paradigm and the Peer-to-Peer paradigm. A network management framework has been designed and developed, which is able to carry on network management tasks and failures detection. Moreover an Artificial Intelligence based autonomous agent has been prototyped, in order to support the network administrator in pursuing his management responsibilities. The Active Networks paradigm has been used in this context to enable network programming. In addition, a software prototype has been developed to enable controlling of DAQ systems by means of distributed discovery services. A discovery service allows network entities to be acknowledged about each other, and enables them to expose and make use of custom services. The Peer-to-Peer paradigm has been leveraged to implement a discovery service to ease configuration and monitoring of distributed DAQ systems. The research and development activity carried on in both domains had the common goal of demonstrating how appropriate middleware can provide the required autonomy to systems under analysis.

Abstract

Computing and software for big science 3(1), 7 (2019). doi:10.1007/s41781-018-0018-8, Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade., Published by Springer International Publishing, Cham, Switzerland

Abstract

Patient-specific 3D models obtained by the segmentation of volumetric diagnostic images play an increasingly important role in surgical planning. Surgeons use the virtual models reconstructed through segmentation to plan challenging surgeries. Many solutions exist for the different anatomical districts and surgical interventions. The possibility to bring the 3D virtual reconstructions with native radiological images in the operating room is essential for fostering the use of intraoperative planning. To the best of our knowledge, current DICOM viewers are not able to simultaneously connect to the picture archiving and communication system (PACS) and import 3D models generated by external platforms to allow a straight integration in the operating room. A total of 26 DICOM viewers were evaluated: 22 open source and four commercial. Two DICOM viewers can connect to PACS and import segmentations achieved by other applications: Synapse 3D® by Fujifilm and OsiriX by University of Geneva. We developed a software network that converts diffuse visual tool kit (VTK) format 3D model segmentations, obtained by any software platform, to a DICOM format that can be displayed using OsiriX or Synapse 3D. Both OsiriX and Synapse 3D were suitable for our purposes and had comparable performance. Although Synapse 3D loads native images and segmentations faster, the main benefits of OsiriX are its user-friendly loading of elaborated images and it being both free of charge and open source.
