Jinghua Feng · 2012
TH-1A is the china's first petaflops supercomputer and is now installed in national supercomputer center in Tianjin,which is ranked No.1 on Top500 list released in Nov.2010.TH-1A system adopts a hybrid architecture of hetero-geneous integration of CPU+GPU and self-intellectual high-speed interconnection system,and shows distinguished system 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 large-scale application tests on TH-1A 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 dynamics simulation,fully implicit simulation of global atmospheric shallow wave,heat flow simulation of earth outer core.These results show that TH-1A has good parallel efficiency and scalability in practical applications.
