I am trying to measure how good the memory locality of a code is on a NUMA machine. While searching, I came across this page:http://www.nic.uoregon.edu/tau-wiki/Gui ... A_Analysis
and I thought it may be exactly what I need to do.
So I installed
On my x86_64 AMD machine with 4 Six-Core AMD Opteron(tm) Processor 8431 and 2.6.32 kernel.
However, when I try to profile my executable, I get the following error:
TAU: Error: Counter HT_LR_MEM_XFR is not available!
I believe this error is related to PAPI, isn't it?
Can anybody tell me how to solve this problem?
Thanks in advance
