Scientists qualified in their respective field of research can submit proposals for access to HPC resources operated by Paderborn Center for Parallel Computing (PC²). We offer multi-million core-hour projects on a recent generation of HPC systems with low-latency interconnect. PC² is one of nine compute centers in Germany of the NHR alliance (Nationales Hochleistungsrechnen). The main focus of Paderborn is on three important application competence areas and their user communities: Atomistic Simulations, Optoelectronics and Quantum Photonics, and Machine Learning for Intelligent Systems. PC² operates its first NHR large scale HPC system with general availability in April 2022.
PC² provides a portfolio of preinstalled applications and offers support for software installation/configuration of project-specific applications. We provide consulting services for all users and we advise them on using the resources in an efficient way. In particular, we provide consulting services in the field of Computational Chemistry and Solid-state Physics. Furthermore, PC² encourages approximate computing and the acceleration of applications with Field-Programmable Gate Arrays (FPGA). Proposals from young scientists and institutions where equal opportunities are concerned are particularly encouraged.

Proposals can be submitted for large projects with more than 12 million core hours.
Apart from large projects also
- normal projects (more than 4 million core hours and <= 12 million core hours, resp. more than 0.1 million GPU hours)
- small projects (4 million or less core hours, resp. 0.1 million or less GPU hours) and
- test projects (code testing and optimization, limited to a 30 day period)
can be submitted at any time.
For details see https://pc2.uni-paderborn.de/hpc-services/our-services/system-access-application.
Who can apply?
Eligible to submit proposals are researchers with a Ph.D. degree or a comparable degree who are members of a public or state-recognized, institutionally accredited German university.
Small projects can only be requested by scientists from universities located in North Rhine-Westphalia (NRW). Exceptions can be made for small proposals with a special emphasis on the development of FPGA acceleration for HPC codes or projects that directly collaborate with PC².
Scientists from universities with local Tier 3-compute center pr resources should only apply for normal or large projects.
All proposals should show the potential of achieving results that are intended to be published in scientific journals or presented at conferences.
How to apply?
Please follow out guides for the project categories: test, small, normal or large projects.
Please note that new simplifications for normal and large proposals are possible:
- Well-known codes: If you use a program that is on our list of well-known codes, then you don't have to include a scaling analysis in the detailed description.
- Project was already scientifically reviewed: If your reserach project has already been reviewed scientifically by the BMBF, DFG, European Union (EU projects), a GCS center or another NHR center then the detailed description is drastically shorter. For details see simplifications.
The project duration of large, normal, and small projects is 12 months.

There are four calls for proposals for large projects per year. The follow-up "Call for Proposals 2023-2" will have an allocation period starting on 1st of April 2023 with a project duration of 12 months.
The normal and large proposals will be ranked based on scientific and technical quality in a peer review process. Small projects are reviewed in a continuous internal process.
Proposals may be granted in their entirety, with a changed volume, or rejected by the Resource Allocation Board of PC².
