Proposals must be written in English. Small requests submitted directly to SURF.

## Summary

NWO's Computing Time on National Computing Facilities provides rolling access to high-performance computing resources including Snellius, LUMI, HPC Cloud, and Grid/Spider infrastructure for computational research. Applicants must hold a tenured or tenure-track position at a Dutch university, UMC, KNAW/NWO institute, or eligible research organisation. Proposals are assessed continuously in order of receipt, with the WGS committee reviewing six times per year.

## Who should apply

- Researchers holding a tenured or tenure-track position at a Dutch university, UMC, KNAW/NWO institute, or eligible research organisation
- Computational scientists requiring access to high-performance computing infrastructure
- Projects with clearly defined compute requirements and feasible timelines
- Applicants able to prepare proposals in English

## Key dates

- Rolling deadline, submit proposals at any time
- WGS committee meets six times per year for review
- Allocations up to 2 years for large allocations; up to 1 year for small allocations or LUMI

## Tips for applicants

- Assess your compute needs realistically before submission; the rebuttal stage is brief, so detail resource requirements upfront.
- Storage is permitted only during the active allocation period, plan data management and archival strategy in the proposal.
- Single-stage assessment with referee input means your proposal quality at submission is critical; rolling review favours clarity and completeness over timing.
