SDC got funded

Svetlana Berdyugina

The establishment of the Science Data Center (SDC) as the third strategic pillar of KIS is an important strategic development of the institute because the SDC connects the two other pillars, the fundamental research and observatory operation. Establishing the SDC was identified as one of the strategic goals of KIS yet in 2013, and it was one of the recommendations of the Leibniz Evaluation in 2015. Our funding application to the national Joint Scientific Conference (GWK) for the strategic expansion of KIS dedicated to the SDC was finally approved on November 13, 2020. From 2021, 1.4 M€ per year will be allocated to the SDC. This will lead to a noticeable staff count increase, an innovative computing infrastructure, as well as broadening scientific collaborations in the area of scientific computing, big data, and artificial intelligence. In addition to enhancing scientific activities at KIS, the SDC will become a valuable big-data infrastructure in Germany and beyond.

We are currently shaping a contract and expect Aperio to begin as soon as possible. The development will be split into a design and implementation phase. The first will indeed require input from scientists intending to use SDC to get a product that benefits future uses as much as possible. We expect the first version of these APIs to be ready for the initial launch of SDC at the end of 2021.

SDC Project Status 02-2021 Petri Kehusmaa

Petri Kehusmaa

SDC Project kick-off was held on in October 2020. Since then, we have come a long way. We have had a workshop with scientists to gather requirements for this new service platform. We have also tested a lot of many different technology options to be selected as building block blocks for the future infrastructure.

Now we have entered the Solution Analysis and Design phase. In this phase we will work with different conceptual design components to be selected into our final blueprint and to be further implemented later this year.

The project team has also deployed Jira Atlassian for Service Management and Documentation. In the future, Jira Service Management will in the future serve SDC as a “Help Desk” ticketing system and knowledge base for platform users. It will provide automated workflows, support portal, knowledge base, feedback system and many more new services for the community.

Solution Analysis and Design Phase steps.

📋 Summary 04 Feb 2021

📊 Project status

Definition & Status of the Project Requirements

In addition to political, technical and security requirements, the workshops in late 2021 helped us clarify expectations that scientists from different disciplines have of the SDC. We continuously update a list of all identified demands. The list includes each requirement's current priority, a possibly assigned responsible, and its current status.

ESCAPE School:  First Science with interoperable data

The Virtual Observatory (VO) is opening new ways of exploiting the huge amount of data provided by the ever-growing number of ground-based and space facilities, as well as by computer simulations. The goal of the school is twofold:

• Expose participants to the variety of  VO tools and services available today so that they can use them efficiently for their own research.

• Gather requirements and feedback from participants

SOLARNET https://solarnet-project.eu

KIS coordinates the SOLARNET H2020 Project that brings together European solar research institutions and companies to provide access to the large European solar observatories, supercomputing power and data. KIS SDC is actively participating in WP5 and WP2 in coordinating and developing data curation and archiving tools in collaborations with European colleagues.

 ESCAPE https://projectescape.eu/

KIS is a member of the European Science Cluster of Astronomy & Particle Physics ESFRI Research Infrastructures (ESCAPE H2020, 2019 - 2022) Project aiming to bring together people and services to build the European Open Science Cloud. KIS SDC participates in WP4 and WP5 to bring ground-based solar data into the broader Astronomical VO and the development tools to handle large solar data sets.

EST https://www.est-east.eu/

KIS is one of the European institutes strongly supporting the European Solar Telescope project. KIS SDC represents the EST data centre development activities in a number of international projects like ESCAPE and the Group of European Data Experts (GEDE-RDA).

PUNCH4NFDI https://www.punch4nfdi.de

KIS is a participant (not a member) of the PUNCH4NFDI Consortium. PUNCH4NFDI is the NFDI (National Research Data Infrastructure) consortium of particle, astro-, astroparticle, hadron and nuclear physics, representing about 9.000 scientists with a Ph.D. in Germany, from universities, the Max Planck Society, the Leibniz Association, and the Helmholtz Association. PUNCH4NFDI is the setup of a federated and "FAIR" science data platform, offering the infrastructures and interfaces necessary for the access to and use of data and computing resources of the involved communities and beyond. PUNCH4NFDI is currently competing with other consortia to be funded by the DFG (final response expected in spring 2021). KIS SDC aims to become a full member of PUNCH and federate our efforts on ground-based solar data dissemination to the broad particle and astroparticle communities.

Ongoing & Future developments

Webpage

Therefore, at the beginning of 2020, KIS-IT intended a relaunch based on a commercially available template for Typo3. However, this had to be stopped due to an increasing workload on IT from SDC and the fact that we were only 2 people in IT last year.

The KIS, therefore, decided to outsource the relaunch. The aforementioned template will still be the basis, but an external web agency will do the design and initial implementation. We have first design drafts and are currently streamlining our site-tree. Feel free to drop by anytime if you are interested in the process.
Costs for the relaunch are of the order of 13 k€.

Network

Dedicated 10 Gbit line between KIS & OT

On Spanish territory, the line is completely free of charge. Nevertheless, the (throughput independent) annual costs for the remaining distance amount to approx. 45 k€ (incl. VAT). Additionally, there are one-time set-up costs of about 30 k€. The costs are

We expect a significantly lower latency on the new line than on the existing internet connection (which will not be affected in any way).
Therefore, we will mainly use it for remote observations and data transport within the framework of the SDC.

The SDC is striving for cooperation with the SCC/KIT in Karlsruhe. By coincidence, the 10 Gbit line enters German territory at the DFN node in Campus North of the KIT. We hope to connect KIT and KIS using the same line without significantly higher costs (despite the high expected load).

New (application) firewalls at KIS & OT

Storage

We are currently scanning all files at KIS to determine the amount of data not accessed for a considerable amount of time. We are planning to invest in a slower tier where such data will automatically be moved. While still visible, access would take longer than for frequently accessed data on the primary tier (however, accessing data on the slower tier will automatically and transparently move it back to the near-line tier). Even this to be introduced slower tier will still not primarily have the character of an archive. Expected costs for such a system are 50-70 k€ (for approx 0,5 PB, incl VAT).
