+Script to run PARSEC benchmarks with gem5.
+The script expects a benchmark program name and the simulation
+size. The system is fixed with 2 CPU cores, MESI Two Level system
+cache and 3 GB DDR4 memory. It uses the x86 board.
+
+This script will count the total number of instructions executed
+in the ROI. It also tracks how much wallclock and simulated time.
+
+Usage:
