C-SCALE project

C-SCALE delivers a new, interconnected data and compute infrastructure that enables and accelerates EO research by providing easy access to Copernicus data sets and High performance & Cloud computing at no cost for European researchers.

C-SCALE stands for Copernicus eoSC Analytics Engine. This project is funded by the European Commission as part of the H2020-INFRAEOSC-2018-2020 call for proposals to support the development of the European Open Science Cloud (EOSC)

C-SCALE brings together researchers, data providers and compute providers at a common table. The project federates European Earth Observation (EO) infrastructure services, such as the Copernicus DIAS and others, and combines these with the capacity (e.g., compute and storage) and capabilities of the EOSC. SURF leads the high performance computing federation for C-SCALE. Other Dutch partners in the project are Deltares and Wageningen University & Research.

Become part of C-SCALE

A growing number of researchers are using the C-SCALE services for their work. You can take advantage of C-SCALE too!

The C-SCALE call for proposals is open for new projects. We welcome your ideas and if granted we will provide the requested resources and support for your project free of cost. If you have an idea but are unsure whether it fits with C-SCALE then please contact us and we will happy to discuss it with you. You may contact C-SCALE via contact@c-scale.eu

Delena cluster

SURF delivers the Delena cluster as one of the high performance computing clusters in the federation. Delena is a dedicated data processing cluster for C-SCALE. Delena is modelled after the Spider cluster and part of SURF's suite of data processing services. Access to Delena (and other high performance clusters in C-SCALE) is provided via the SURF Research Access Management (SRAM) system.

Delena documentation

Except for the access method, the setup of Delena is very similar to that of the SURF Spider cluster. We refer Delena users to the Spider documentation for more details on how to perform your work on the Delena cluster. In case of questions or issues you may contact SURF via our service desk

Important differences compared to Spider:

1) Access to Delena is provided via the C-SCALE project that makes use of SURF Research Access Management (SRAM) for access management. Documentation for access to Delena - following an approved grant from C-SCALE -  can be found here 

2) Monitoring dashboards are available here. These require your username and password for logging in.

3) The Web public view maps the /project/[PROJECTNAME]/Public folder in the project space to the URL https://public.delena.surfsara.nl/project/[PROJECTNAME]/
