The project organization of PASC is depicted in the figure below.

The Steering Committee consists of the presidents or rectors of the universities that co-signed this project (USI, U. of Geneva, Zurich, as well as EPFL and ETH Zurich). It approves all major funding decisions, and nominates upon recommendations from the Project Director the members of the project leadership, the Scientific advisory Committee (SAC), and the members of the User Reference Group (URG) that represent the communities in the Application Support Network (ASN).

The Project Leadership consists of project director (Prof. Dr. Thomas Schulthess), the ASN coordinator (Dr. Michele De Lorenzi), and the coordinator of the co-design pillar (Prof. Dr. Olaf Schenk).

The Project Director is responsible for all strategic aspects of the PASC, oversees interactions with industry as well as with the SAC and the URG, and reports to the steering committee. Furthermore, he is making sure the developments of the ASN and co-design pillars and the system construction projects at CSCS are aligned. The respective pillar coordinators manage all operational aspects in the pillars.

The Application Support Network (ASN) are supported with technical staff funded by the ASN pillar and employed at the participating universities. The head of the community engagement section at CSCS, Dr. Michele De Lorenzi, coordinates the ASN pillar.

The co-design pillar consists of projects selected via peer review process. Prof. Dr. Olaf Schenk who leads a research group in computational science at the University della Svizzera italiana is the coordinator of this pillar.

The Scientific advisory Committee (SAC) members will be internationally recognized scientists in the area of supercomputing. They will include experts from the computer industry as well as labs that are involved in similar co-design projects. The project director proposes candidates to the steering committee. The members of the SAC are:

• Bruce Harmon, Ames Laboratory and Iowa State University
• Thomas Lippert, Jülich Supercomputing Centre
• Jeffrey Nichols, Oak Ridge National Laboratory
• William Tang, Princeton Plasma Physics Laboratory

The CSCS User Reference Group (URG) is a standing committee of professors from Swiss Universities that represents the user community and advises the CSCS director. Each of the communities in the ASN pillar will be represented in the user reference group. In the context PASC, the user reference group will advise the project leadership on how to prioritize the directions to be taken in the co-design pillar.
