PRACE 23rd call for proposals continues to support diversity, equity and inclusion


October 22, 2021 – The 23rd call for proposals for access to PRACE projects received 61 eligible proposals, of which 43 were awarded, totaling 1.997 billion core hours. This brings the total number of Project Access projects awarded since 2010 to 916. Taking into account the six multi-year applications from calls 19 and 21 and the 10.73 million core hours reserved for centers of excellence, the total computing time that PRACE has so far is around 32, Reached 2 billion core hours.

Proposals under the 23rd call will be led by senior researchers from 14 different countries. International collaboration is greatly supported by the award-winning proposals as they involve team members from a number of countries including Kazakhstan, Japan, USA, Canada and Brazil.

Eight scientific areas are represented among the award-winning proposals: 14 proposals relate to the areas of chemical sciences, 10 to basic components of matter, 10 to engineering, 3 to earth system sciences, 2 to biochemistry, bioinformatics and life sciences, 2 to universe sciences, 1 to mathematics and Computer science and 1 for physiology and medicine.

This call was an opportunity to reaffirm PRACE’s commitment to diversity, equity and inclusion (DEI). At the initiative of the Chair of the PRACE Science Committee and the Steering Committee, steps have been taken to identify and mitigate potential unconscious biases within the Access Committee’s review body. These measures include appointing members of the reference body to uncover arguments that diverge from the principles of equal opportunities. With 11 proposals led by a scientist out of 61 and 7 out of 43 proposals made, the procedure shows a neutral treatment towards the gender of the main researcher of the proposal. With these continuous efforts, PRACE aims to continue supporting DEI.

Details of a selection of excellent proposals are highlighted below:

Magnetic moment of the muon: new physics or not? received 222 million core hours on HAWK at GCS / HLRS (Germany). The project is led by Dr. Laurent Lellouch from CNRS and the University of Aix-Marseille, France. The research team intends to conduct new and critical simulations to reduce both systematic and statistical uncertainties between the calculation and measurement of the magnetic moment of an elementary particle called a muon.

Thermal conductivity of organometallic frameworks (TC_MOFs) received 39 million core hours of high-level support on Piz Daint at ETH Zurich / CSCS (Switzerland). This is a two year project and is led by Dr. Raffaela Cabriolu from the Swiss Federal Institute of Technology in Lausanne, Switzerland. This project will contribute to a fundamental understanding of how changes in pore topology and functional groups affect the thermal conductivity (TC) of organometallic frameworks (MOFs).

GASTON received 30 million core hours on MareNostrum at BSC (Spain). The project is led by Dr. Laurent Selle from the Toulouse Institute of Fluid Mechanics, France. The project intends to investigate the microscopic and macroscopic structure of the submerged flame front in porous networks in order to evaluate the validity of current and newly proposed volume averaged modeling strategies.

Understand how mutations in the kinase domain of PI3Kα alter lipid kinase activity using HDX-MS and CryoEM experiments and molecular dynamics simulations received 35 million core hours on Marconi100 at CINECA (Italy). The project is led by Dr. Zoe Cournia of the Biomedical Research Foundation of the Academy of Athens, Greece. This project aims to understand the molecular mechanisms by which oncogenic mutations in the kinase domain of PIK3CA on membranes are activated, revealing new molecular insights that can be used to develop new cancer therapy strategies.

Generally relativistic MHD simulation of a transitional accretion disk received 20 million core hours on JUWELS cluster at GCS / JSC (Germany). The project is led by Dr. Oliver Porth from the University of Amsterdam, Netherlands. The research team claims that its simulation may enable the most direct link yet between accretion disk theory and observations, and lead to a major breakthrough in understanding the black hole accretion phenomenon.

New radiation therapy approaches based on differently dosed methods received 16 million core hours on Joliot-Curie SKL at GENCI / CEA (France). This project is led by Dr. Yolanda Prezado from Institut Curie, France. The project proposes to explore new cancer treatment techniques based on novel dose delivery methods and different particle types (heavy ions) and energies (high energy electrons).

All information and summaries of the projects awarded under the 23rd PRACE Call for Proposals are available on the PRACE website.

the 23rd call for Proposals for PRACE Project Access (Tier-0) was open from March 23, 2021 to April 27, 2021. Selected proposals will receive PRACE resource allocations from October 1, 2021 to September 30, 2022 24. Call for Proposals for PRACE Project Access (Tier-0) is open from September 9, 2021 to November 2, 2021, 10:00 a.m. CET, see here: -for- suggestions-for-project-access.


The mission of PRACE (Partnership for Advanced Computing in Europe) is to enable effective scientific discovery and technical research and development in all disciplines to improve European competitiveness for the benefit of society.

PRACE seeks to achieve this mission by providing world class computing and data management resources and services through a peer review process.

PRACE aisbl is funded by the PRACE members The implementation phase of PRACE is funded from the EU research and innovation program Horizon 2020 (2014-2020).
