Re: [Gems-users] Prefetcher in GEMS

["Mike Marty" <mike.marty@xxxxxxxxx>]

I don't believe the released version of Ruby includes a prefetcher.
Where did you add the prefetching code?  The common way to do this is
to develop a Prefetcher module that is included in the L1 (for
prefetches into the L1) or L2 (for prefetches into the L2) controller.
 The module will deliver prefetch messages/wakeups to the controller

p.s.  sorry for the prior personal e-mail exchange on gems-users.  Its
all Dan's fault :-)
