I'd like to create a statistic which can be updated by all caches (in
this case, it's a histogram corresponding to the frequency of certain
events). Is there any way to do this using the m5 statistics package?
As I understand it, by default all statistics are local to the
instance of their simobject, and I'm not sure that there's any simple
way to have a statistic shared across all instances of a simobject.
If the statistics package doesn't support it, what might be another
good way to implement this tracking? As far as I can tell the only
other way would be have one cache, say cache 0, be the one to
coordinate, while all caches are provided a shared variable which they
write to and cache0 reads from to update the histogram.
Thanks,
Nick
