Virtual interface architecture communication model and optimum strategy
Meie Dai · Journal of Tsinghua University(Science and Technology) · 2003
Traditional TCP/IP has greatly restricted communication performance of parallel systems. However, user level communication can resolve such problems as unnecessary data copying and work space switching. Virtual interface architecture (VIA) is an outstanding user level communication technology which provides the cluster system with efficient and secure communication ability. This article analyzes the VIA industry specifications, demonstrates its structures and features, and explains its basic programming model through a typical example. The system performance was improved through a self adjusting factor which enables the system to recognize available nodes. The greatly improved VIA communication system performance is then illustrated by testing the transfer of a large block of data.
