[Gems-users] Creating loads/stores that aren't stored in the cache

[Philip Garcia <pcgarcia@xxxxxxxx>]

hello,
I have a question concerning ruby.  In my setup, I have a set of load  
and store instructions that I know are from stream accesses, and I  
don't want them to pollute the cache by saving them inside it (as they  
are unlikely to be accessed again anytime soon).  However, these loads  
and stores could be located in the cache (as they're not to non- 
cacheable address).  Is there any way to send hints along to Ruby to  
tell it to not save the values in the cache (I'm using a  
MOESI_CMP_directory_m protocol).  If this isn't currently possible,  
does anyone know what I would have to modify to allow these non-cache  
loads/stores to operate properly?
thanks,
Phil
