SSCIENCECIENCE - TTERAGYROIDERAGYROID

• Project couples cutting-edge grid technologies, high-performance computing, visualization and computational steering capabilities to produce a major advance in soft condensed matter simulation

• Interesting effects only for particular parameter values. Use TeraGrid and UK Reality Grid to generate many small computations, then migrate interesting ones to large systems, like PSC’s TCS.

PSC contributions:Led effort to organize and execute the TeraGyroid project

Enabled largest Boltzmann lattice calculation ever (10243)
