【Abstract】 WT5BZ]The implementation techniques of performance analysis and visualization display on the distributed shared memory system have been described. The tools consist of three parts, an events detect and collect tool, a data analysis tool, and a visualization display tool. The event collect tool gather interested events about application and underlying system. In order to lighten user’s burden, some of instrument are implemented in the runtime library and shared memory coherence protocol. So the event can be related to a memory address easily and be mapped to the application’s resource code. It is convenient for user to view and improve his parallel program.更多还原
