[Gems-users] Ruby Cache Features

[pana <panasa1@xxxxxxxxx>]

Hi, 

I use Gems/Ruby with the MOESI_CMP_NUCA protocol. I have 8 cpu on a single chip and a shared D-NUCA cache memory (tetris like clustered)
I need to know some features about the cache memory and the protocol but I didn't find them neither in documentation nor in the code.

cache:
- Is L2 a Direct Access memory?
- Are L2 addresses logical or physical?

protocol:
- Which is the Promotion Policy? i.e. How the data change bank inside the cache? and when?
- Where the new data are written in? In the local bank cluster?

greetings
Francesco
