#1: when a store to address x occurs, |
|||||||||||||
| update all the remote cached copies |
||||||||||||||
| • | To do
this we need either: |
|||||||||||||
| – | To
broadcast every store to every remote cache |
|||||||||||||
| – | Or
to keep a list of which remote caches hold the |
|||||||||||||
| cache
line |
||||||||||||||
| – | Or at
least keep a note of whether there are any |
|||||||||||||
| remote
cached copies of this line |
||||||||||||||
| • | But
first…how well does this update idea |
|||||||||||||
| work? |
