Re: [Gems-users] GETS Misses

[Alaa Alameldeen <alaa@xxxxxxxxxxx>]

What you are asking for is not clear. What do you mean by "from the 100 
GETS misses in proc 0, there are 40 hits in proc 1 ...etc."? Do you want 
to track the last processor that touched each block? Each GETS miss can 
be fetched from either:
- Any of the caches of the other processors OR
- Memory

You can include a new field as a property of cache blocks in 
ruby/system/CacheMemory.h that you set to the last processor that 
touches a block. However, when the block is written back to memory, you 
should reset this field to a default of "N/A" or something similar. 
Conversely, when you read a block from memory, you should set this field 
to the same default. This way you know for each GETS miss whether a 
block last existed in another processor's cache or memory.
I hope that helps.
