Further work has superceded some of the results shown in the paper.
- The "mod 4096 with rep prefix" instructions retired issue described
in the paper is incorrect. On all Intel and AMD processors the
rep prefixed instruction only counts as one instruction.
The extra 4096 factor is an artifact from extra instruction counts being
generated when page-faults happen. See
for ongoing research into these issues.
- The valgrind and qemu tools have been modified to have better performance
and to more accurately account for retired instructions.
