Memory Bandwidth

Postby digikzes » Thu Sep 30, 2010 12:47 pm


I want to calculate Memory Bandwidth (DRAM - Cache L1, L2) using papi. Can any one please tell me how I can calculate it using the available counters?

Can I use papi to trace the amount of data transfered at a give clock or..

Thanks in adv.

I am trying to do the same thing for my app, to track the flops to DRAM bytes. I know that there's a counter in Craypat that you can use by setting PAT_RT_HWPC=normal.
