D5.2 Interoperable access policies: analysis and recommendations

Lead partner: FZJ

This deliverable:

  • Contains an analysis of access policies of 20 European e-Infrastructures in the areas of High-Performance Computing, High-Throughput Computing, Cloud Computing, and Data, which are open for use by European scientists
  • Comparation and contrasts them with the requirements of European research communities with a focus on the High-Energy Physics and Radio Astronomy fields and the use cases described in SPECTRUM Deliverable D5.1 (Representative use cases: analysis and alignment)
  • Contains recommendations for the future evolution of the access policies to meet the current and future needs of European researchers

Background and Relevance

Deliverable D5.2 offers a detailed assessment of current access policies in European HPC, HTC, cloud, and data e-
Infrastructures. This work is essential for disciplines like radio astronomy and high-energy physics, where secure,
efficient, and remote access to computational resources is critical to processing vast amounts of real-time data. The
document also cross-references these systems with use cases identified in Deliverable D5.1

Project Recommendations

SPECTRUM D5.2 provides a clear comparative analysis and actionable recommendations to move toward policy
interoperability. Key recommendations include:

  • Adopt long-term, flexible resource allocation processes.
  • Enable e-Infrastructure-wide use of resource allocations and quotas.
  • Extend scheduling/orchestration to support interactive compute use cases.
  • Introduce high-level general and domain-specific user interfaces.
  • Introduce common AAI services across European e-Infrastructures.
  • Ensure Reliable and Unattended execution of long-running workflows.
  • Provision efficient standard, low-level SW interfaces.
  • Establish feedback/improvement/planning loops for research communities and e-Infrastructures.

The deliverable will serve as one of the inputs to the second phase of SPECTRUM (months 16-30) and eventually for the SRIDA and Technical Blueprint, to be delivered at the end of the project.

Broader Impact

Implementing the recommendations from D5.2 will boost European leadership in data-intensive science and
heterogeneous resource federation models, including large-scale compute and storage capacity to be procured and
made accessible at the pan-European level. Harmonized policies will:

  • Improve efficiency of distributed HPC and data resources.
  • Strengthen cross-disciplinary collaborations (e.g., climate science, medicine, AI).
  • Accelerate FAIR data adoption and open science initiatives.
  • Build a robust and future-proof European scientific infrastructure ecosystem.
