Re: [Gems-users] Ruby prefetch module?

[Carole-Jean Wu <carolewu@xxxxxxxxxxxxx>]

Hi Mike,

Do you know if the most recent GEMS release include a prefetch module yet? Otherwise, would you suggest a place to where the prefetch messages should be inserted? 

As I was digging through the mailing list responses, it seems like many people are modifying the generated codes directly. Is there better place (non-generated, protocol-dependent) to inject prefetch requests?

thanks very much,

Carole

Yes, we have a stream-based prefetching module in one of our internal
trees for both L1->L2 prefetching and L2->memory.  I can see what it
would take to port this, or at least include the files, in our upcoming
release

The basic idea is that the Prefetcher module observes accesses and then
generates prefetch request messages to the appropriate controllers.  It
directly enqueus a message into a special in_port for each controller
