Second International Workshop on Combinatorial Scientific Computing (June 21th-23th, 2005)


Second International Workshop on Combinatorial Scientific Computing (CSC05)
June 21–23th, 2005 at CERFACS, Toulouse, France





The Second International Workshop on Combinatorial Scientific Computing (CSC05) will provide a forum for researchers interested in the interaction of combinatorial mathematics and algorithms with scientific computing to discuss current developments in research.

CSC05 follows the pioneering SIAM Workshop on Combinatorial Scientific Computing (CSC04) held at San Francisco in Feb 2004. The CSC04 Workshop, attended by close to a hundred participants, featured three plenary talks and 21 selected talks on the themes of sparse matrix computations, high-performance algorithms, combinatorial problems in optimization and automatic differentiation, mesh generation, computational biology, and combinatorial matrix theory. The CSC05 Workshop aims to bring together researchers interested in these themes as well as other aspects of combinatorial mathematics and algorithms in scientific computing, broadly interpreted. Researchers in emerging application areas as well as theoretical areas that intersect with combinatorial scientific computing, e.g., information science, networks, bioinformatics, and combinatorial optimization, are invited to participate.

Students are very much encouraged to participate. Low registration fees (that include the lunches and the coffee breaks) are offered and a limited number of grants to support their local accomodation are also available.

ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.

The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).Read more

A CERFACS article distinguished in Scilight (https://doi.org/10.1063/10.0017474)

CERFACS |  9 March 2023

The recently published paper in Physics of Plasma: "3D particle-in-cell study of the electron drift instability in a Hall Thruster using unstructured grids," by W. Villafana, B. Cuenot, and O. Vermorel ( attracted the attention of Scilight (), whose goal is to present the most interesting research in the physical sciences published in AIP journals."Read more
