Study of the Large Scale Parallel Operating System
Shao Zong-yo · 2013
By analyzing the operating system running in a supercomputer simulator,it is found that different nodes in the supercomputer use different part of an operating system.However,a traditional operating system cannot meet the demand.In such case,a heterogeneous large scale operating system is designed and a prototype named SandOS is implemented based on the simulator.The prototype includes light weight kernel operating system SandPOS for compute nodes,FileServer for I/O nodes and MonitorServer for service nodes.By comparing SandPOS with traditional operational system in memory overhead,schedule efficiency,run efficiency and address translating efficiency,result shows that in large scale parallel system,SandOS has better efficiency than traditional operational system.
