[Gems-users] prefetch in opal

[Jerry Lin <cosjerry@xxxxxxxxx>]

Hello all,
I'm wondering about what kind of prefetching that opal implemented.

I saw Next Line prefetch in opal/system/rubycache.C.

But in ruby's dump file, the prefetch count seems to be the software prefetch.

Is the prefetching policy implemented in opal a HW prefetch or SW prefetch?

Any advice would be appreciated. 

 
Thanks for helping.
