Purpose: Feature Fix Description: Changed so the "pio_perf" module handles creating and destroying the MPI Comm. Worked it so we get the minimum, maximum, and average times over a set of iterations. Solution: Lots. Had to pull the MPI Comm code from the "pio_engine" module and place it in the "pio_perf" module. Then worked on a way to have all processes send their time output to process 0, who collects it and gives back the min, max, and avg times for the iterations. Platforms tested: Linux. Doesn't work if you use more than 1 processor...*hrmph*
