Scientific Computing Service (SCI-uc)
Servicio de Computación Avanzada para la Investigación · University of Cantabria

The Scientific Computing Service (SCI-uc) is a specialized unit of the University of Cantabria that provides advanced computing infrastructure and technical support for university research groups, research organizations, and companies involved in research and innovation. Its mission is to facilitate access to and effective use of HPC infrastructure, supporting scientific and technological work.
SCI-uc supports two infrastructure models: Hosting, where infrastructure is operated through a common SCI-uc service framework, and Housing, where research groups operate and manage their own clusters. Access for external research users and industry collaborations is subject to project application and technical validation. See the SCI-uc website for current service information.

About the Service
SCI-uc provides the following services:
- Equipment housing and infrastructure hosting: secure rack space, power, cooling, network connectivity, and monitoring at the 3Mares data center for research computing equipment, including externally acquired systems.
- HPC system installation and configuration: design, deployment, and optimization of environments tailored to research projects and integrated with existing infrastructure and workflows.
- Maintenance and technical support: continuous monitoring, maintenance, and periodic upgrades to support reliability, performance, and service continuity.
- Specialist consulting: tailored technical solutions and advice on efficient resource use and HPC best practices.
- Procurement advice: guidance on hardware and software acquisition, considering project performance, scalability, and budget requirements.
The 3Mares facilities are intended to provide a professionally managed, highly available environment for hosted equipment.
This documentation focuses on practical access and use. For cluster equipment, resource specifications, software, storage policies, and service procedures, use the guides linked above; these pages are maintained in their respective sections so operational details can be updated independently of this introduction.
For help with access, resources, or technical issues, contact soporte.sci@unican.es or consult the support channels.
