Design and Realization of HPC Cluster
Chen‐Xu Wu · Journal of Xiamen University · 2004
Using Oscar-2.3.1 and on the basis of Redhat 9.0 Linux,we design and realize a high performance computing (HPC) cluster system with one server and 8 clients.A VASP package supporting parallel computing in cluster system is used to calculate the self-consistent time of cubic carbon and hexagonal ZnO with different number of atoms in a super primitive cell.It is found that the performance of the cluster system using parallel computing increases with number of nodes,which is more distinct as the super primitive cells used become larger.This shows the advantage of HPC cluster in massive computation.To meet the challenge of massive computation and simulation in physical research,the power of HPC cluster can be further improved through constant updating both in software and hardware,which can be achieved more easily in comparison with that of supercomputers.One example is the optimization of parallel package and the introduction of a 1 000 M switcher and 1 000 M network cards to accelerate the communicating speed.
