Abstract
The ULTRA (UAH Logging, Trace Recording, and Analysis) instrumentation system provides an accurate and low-cost means of collecting traces of Message Passing Interface (MPI) program execution. These traces preserve the original parallel program's data-dependencies by recording each MPI operation performed; the message source, destination, and size; and the number of application instructions preceding the operation. Using these traces enables low-cost simulations for determining the performance of various node and communication hardware combinations although the cluster used to collect the data and the cluster being simulated differ significantly.
