Hi!

 

 

I've run the bw_mem test of lmbench and it said that my Bandwidth is 4.95GB/s..

 

 

But how can i get this Bandwidth without SW prefetching?

 

And without memory affinity?

 

This is for using with Roofline Model ( http://www.eecs.berkeley.edu/Pubs/TechRpts/2008/EECS-2008-134.pdf http://www.eecs.berkeley.edu/Pubs/TechRpts/2008/EECS-2008-134.pdf ) of my machine which has:

 

Intel Pentium T3200

Main Memory; Dual Channel DDR2 667 1024+2048=3GB

 

 

Thanks

I would like to verify some more information about your system. Can you please post your dxdiag report here?
