As BEEBS is being characterized this summer, this is a good opportunity
to see whether the benchmarks (or a subset of them) show significant
differences wrt Worst Case and Average Case Performance / Energy
Consumption. If not, can we find some that do?
Here is why I think this may be interesting: Provided the difference is
large enough, an interesting research question is whether MAGEEC will
find different optimizations for the WC vs the AC, even though the
source code is the same. ;)
Would it not be cool if we could demonstrate that MAGEEC automatically
finds different optimizations for WC vs AC Time / Energy for programs
where there is a significant difference between these two cases? To
allow MAGEEC to do this, we need a few benchmarks characterized wrt
WC/AC behaviour and there being a significant difference between these.
If MAGEEC can indeed to that, I think this would add significant value
to a MAGEEC evaluation paper.
Greg, please can you look into this and let me know your observations,
and how difficult/easy you think this would be to do?
