Supercomputer

High Performance Computing (HPC) deals with solving difficult problems that cannot be solved on individual computers. It may be because the calculation takes too long or the memory is insufficient. Special attention is paid to scalable parallel communicationhigh node level performance and omitting unnecessary calculations.

With NAStJA, a framework has been created that can efficiently carry out scale bridging simulations. In addition, it has been flexibly designed so that experimental approaches to solutions can be tried out quickly. NAStJA makes it possible to dynamically adapt the computing region completely autonomously and without collective communications.

Applications

Phase-field Crystal

Phase-field Method

Cellular Automata for biological applications
