PASC activities are organized in four pillars.

1. The Application Support Network (ASN) pillar consisting of experts at participating universities that assist researchers in exploiting HPC platforms.
2. The co-design projects pillar aimed at bringing together the development of scientific models, application codes, as well as the numerical and system software environment needed in order to optimally exploit emerging supercomputing computing platforms for high-end simulations of the future.
3. The institutional computing system pillar supporting the procurement of institutional computing systems necessary for the development work in the co-design pillar.
4. The training pillar supporting the Swiss Graduate Program Foundations in Mathematics and Informatics for Computer Simulations in Science and Engineering (FOMICS).
