    Calculate Max Memory Bandwidth without prefetch

    JoseRibeiro

      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 ) of my machine which has:


      Intel Pentium T3200

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