Some background information

I was told by my PI to graph the number of physical memory addresses that are passed through our simulator, and compare these to the structural addresses that these are mapped to. Many of the simulations didn't complete because the files' simpoints needed to be recompiled, so we recompiled the simpoints. To do all of this, we are using a software called Intel PIN tool that is a program through which one can run C++ code with a great deal of control over how the code is run. Simpoints are sets of instructions that are run. So, for example, if we compile 3 simpoints per benchmark, we are given 3 sets of output per benchmarks, each set being the result of ~25,000,000 instructions. We are using SPECfp as a benchmark, which is a standard floating-point algorithm benchmark that works by running state-of-the-art algorithms such as the Einstein evolution algorithm and quantum mechanical simulations.

I apologize that I can't give more accurate details as to the actual code that I'm working with, but I'm not really allowed to talk about it because the research is going towards an unreleased paper.
