EuroHPC Extreme Scale Access

EuroHPC Joint Undertaking. Evidence checked 12 October 2026.

Start here

Unverified current status: EuroHPC Extreme Scale: linked portal is closed Checked 14 November 2026.

Research teams investigating exceptionally large allocations. Confirm the current submission route with EuroHPC before preparing a proposal: the call page says continuously open, but its Apply now link reaches a portal marked Closed with its Register to apply button disabled.

This is the linked portal's status, not a finding that every Extreme Scale route is closed. The last listed 2026 cut-off has passed; 31 December 2033 is not treated here as a verified next practical evaluation date. This status needs a new check before relying on the route. Official source and next step

Check current status and next steps

Who can apply?

Academic and public research organisations, industry and public-sector bodies proposing civilian work in English. The lead organisation must be established in an eligible EU Member State or associated country for the requested system, and the principal investigator must remain employed there until at least three months after the allocation ends.

How do I take the next step?

First confirm the current submission route with EuroHPC: the call page links to a closed portal. For a usable call, choose the scientific, industry or public-administration track and prepare the required online form and Project Scope and Plan, showing technical readiness, impact, resource needs and why smaller-scale HPC is insufficient. An application must pass review before any award.

Recorded deadline

Recorded deadline: The call page still lists the passed 26 October 2026 cut-off. On 14 November 2026 it says continuously open, but its Apply now link leads to a portal marked Closed with its Register to apply button disabled. A usable next submission route and practical evaluation cut-off remain unverified; do not treat the listed 31 December 2033 date as an established next round.

Check the official programme before applying. A recorded region is not a decision about your eligibility, and an allocation is not guaranteed.

Evidence and limits

Extreme Scale is for high-impact, high-gain projects that need very large compute, storage and support allocations. Code testing, porting and optimisation belong in EuroHPC Benchmark or Development Access instead; an Extreme Scale proposal must show that the application can use the requested system effectively. Source
The application has an online form and a Project Scope and Plan. It must cover relevance and impact, technical feasibility and adaptation, resource consumption, project management and why smaller-scale HPC is not sufficient. Missing or non-conforming material can fail the administrative check. Source
At the 12 October 2026 source check, the call page showed a 26 October 2026, 10:00 CET cut-off, one-year allocations, a maximum six months from cut-off to resource access and an end-March 2027 decision for the allocation period starting 1 April 2027. Source
Evaluation includes an administrative check, hosting-site technical assessment and external scientific review. Awards can be made in full, reduced or rejected according to merit and available resources; a published call does not establish current capacity or guarantee an award. Source
Eligible open research and development access is currently free, but the selected hosting entity's access terms still apply. Awarded projects must publish an abstract and report results; the record does not treat an allocation decision as an active account or completed compute use. Source
On 14 November 2026, the official call page's Apply now link led to an Extreme Scale portal marked Closed, with Register to apply disabled. This observation concerns that linked portal, not every Extreme Scale access route. Source

Fit, eligibility, application evidence, review, cost boundary and the live call timetable were checked on 12 October 2026. The live call page says 26 October while the downloadable Full Call Details dated 17 April 2026 says 19 October; this record uses the live-page date and exposes the discrepancy. The 14 November 2026 check adds the call-page/linked-portal status conflict only; the other programme details retain their 12 October check. Confirm a current submission route with EuroHPC before preparing a proposal. This is not a finding that all Extreme Scale access has ended.
