The C20 commission was founded by the International Union of Pure and Applied Physics (IUPAP) , with the following mandate:
To promote the exchange of information and views among the members of the international community of physicists in the area of Computational studies of problems originating in or relevant to physics, including
- numerical and symbolic models and algorithms for the simulation of physical systems
- computational control and data processing of experiments
- programming and computational environments
- the physical basis of computer machinery.
To recommend for Union sponsorship international conferences which qualify for support under Union regulations (see IUPAP Coutumier).
To initiate such conferences as their need arises from the evolution of the Commission field.
To assist in the organization of such conferences when practical. To ensure the compatibility of international conferences in its field and to discourage clashes and incompatibility of dates.
To promote the free circulation of scientists; to assist conference organizers in ensuring such free circulation and in resolving potential infringements.
To organize where feasible the award of medals or other testimonials of excellence in its field.
To publish where feasible newsletters, circulars, occasional books, journals or handbooks in its area.
To maintain liaison with other IUPAP Commissions, with the Commissions or Committees of other Unions or of the International Council of Scientific Unions (ICSU) or other scientific organizations, with a view to collaborating and cooperating in sponsoring joint conferences and to participating in joint projects when need arises.
In particular to maintain close liaison with the General Commissions of IUPAP (SUNAMCO, Physics Education and Development), so as to ensure suitable input from its field into these physics-wide activities.
To make available to each General Assembly of the Union a summary of activities and progress in its field since the previous Assembly.
