Build System - How to run or modify gem5's build system. The mcf benchmark has highest L1 cache misses per 1000 instructions in both CPU2000 and CPU2006 benchmarks. However, the performance pitfall of this technique is squashing speculatively executed instructions and re-executing them in case of aborts, ultimately resorting to serialization in case of repeated conflicts. Unfortunately the steps listed to create a disk image did not work for me when booting with gem5. Existing cloud benchmark suites for scale-out or scale-up computing are not representative of the most common cloud usage, and are very difficult to run on a cycle-accurate simulator that can accurately model new hardware, like gem5.
