Main tasks within ice2sea: Key processes (W2)
Description of institution: CSC – Tieteen tietotekniikan keskus Oy, the Finnish Information Technology Center for Science (CSC – IT Center for Science Ltd.), is one of the largest supercomputing centres in Northern Europe. CSC’s activities include supercomputing and Grid computing, data management, scientific applications, development of open source simulation software (e.g. Elmer), Finnish University and Research Network (FUNET), as well as training and education services. CSC has 150 employees and the turnover without investments in 2006 was close to 16 MEUR. CSC is a non-profit company owned by the Finnish State. The open source simulation software Elmer, which will be used as a simulation tool within W2, is maintained and developed by CSC.
Department name: Not applicable
Staff member: Thomas Zwinger
Profile of staff member: Thomas Zwinger is application specialist in the group of “Computing Environment and Applications” at CSC. TZ holds a doctorate in Mechanical Engineering and has an experience of more than a decade in geophysical flow modelling, with a recent emphasis on the application of Finite Element Method (FEM) to coupled thermo-mechanical problems in Glaciology. Inside CSC, TZ is part of the development team of Elmer, an open source FEM code that has been adapted to simulations of complex ice-dynamics. Further expertise of TZ also covers the usage of parallel numerical applications on large computing clusters, which is a pre-requisite for high resolution simulations of larger (even continental) size ice masses.
