Abstract: TH-lA is the china's first petaflops supercomputer and is now installed in national supercomputer center in I}ianjin,which is ranked No. 1 on Top500 list released in Nov. 2010. I}H-lA systcxn adopts a hybrid architecture of hetero- geneous integration of CPU}GPU and self-intellectual high-speed interconnection system,and shows distinguished sys- tem usability, performance stability and application scalability in quite a few high performance computing areas, provides an important platform for science research and technology innovation. In this paper,several largcscale application tests on TH-lA were introduced, such as the oil seismic data processing, aircraft flow field simulation, biomolecular dynamics simulation, magnetic confinement fusion numerical simulation, turbulent flow simulation, crystal silicon molecular dy- namics simulation, fully implicit simulation of global atmospheric shallow wave, heat flow simulation of earth outer core. These results show that TH-lA has good parallel efficiency and scalability in practical applications.
Key words: TH-lA, High performance computing, Application, Parallel efficiency
