ABSTRACT:
A multiprocessor system and method for minimizing perturbations while monitoring parallel applications. Perturbations due to monitoring the application are minimized by synchronizing all the nodes within the system to a very accurate global time clock such that all the nodes running the application stop and restart running the application at the same time. Within the time period bounded by the stop and restart time, all the performance monitoring data is transferred from performance monitoring data buffers to a secondary memory.
