These views provide information about the interactions among tasks in a parallel PVM program, to assist in debugging and performance tuning. To analyze a program using XPVM, a user need only compile his program using the PVM library, version 3.3 or later, which has been instrumented to capture tracing information at run-time. Then, any task spawned from XPVM will return trace event information, for analysis in real time, or for post-mortem playback from saved trace files. <keywords>execution trace visualization; parallel debugging <category>ppt-exe <contact>Jim Kohl / kohl@msr.epm.ornl.gov </urc>
