Splash2 Benchmark

Today, I am going to run a few simulation and write scripts that could automate the process.

1) create a new disc image that contains the libm.so.2
This has to be done before taking any checkpoints, otherwise it doesn't save the diff file.
Use the following command
sd0.save-diff-file "diff-file.craff"
then
use the craff utility to merge two files together, if you are using simics 2.0.X
../../x86-linux/bin/craff -o sarek-with-libm.craff "diff-file.craff" sarek-solaris9.craff

2) read the GEMS wiki about making benchmarks, and verify that our benchmarks conforms to the standard practice of GEMS
3) read the GEMS wiki about write simulation script
4) run shared-counter benchmark using simulation script
5) understand the shared-counter benchmark results
