NTV - The NAS Trace Visualizer

Abstract

NTV is a trace visualization tool that uses trace files produced using The IBM SP2 MPL Trace Facility or The Automated Instrumentation and Monitoring System (AIMS) Version 2.2 or Version 3. NTV detects the trace type, so the same version of NTV works for both trace formats. A distinctive characteristic of NTV is that it uses static displays rather then time varying displays. This, in combination with mouse controlled zooming, gives the user the ability to get a global view of the execution and a focused view of details. The principal display is a time line display that shows a color coded time line for each processor. The color coding shows the processor status. Messages between processors are indicated by lines connecting the processors involved in the communications.
