Hi Eranian:
Why not the pfmon cannot aggregate the sampling number based on the same
ip address? Like the following sampling result, where IP addresses are the
same, 0x0000003ab6076edf.
124 14.34% 14.34% 0x0000003ab6076edf memcpy+0x3f</lib64/libc-2.5.so>
118 13.64% 27.98% 0x0000003ab6076edf memcpy+0x3f</lib64/libc-2.5.so>
109 12.60% 40.58% 0x0000003ab6076edf memcpy+0x3f</lib64/libc-2.5.so>
90 10.40% 50.98% 0x0000003ab6076edf memcpy+0x3f</lib64/libc-2.5.so>
77 8.90% 59.88% 0x0000003ab6076edf memcpy+0x3f</lib64/libc-2.5.so>
39 4.51% 64.39% 0x0000003ab6076ed7 memcpy+0x37</lib64/libc-2.5.so>
The pfmon command line is
pfmon --follow-all --aggregate-results -e MEM_LOAD_RETIRED:L2_MISS
--no-cmd-output --with-header --smpl-module=pebs --short-smpl-periods=20011
--long-smpl-periods=50021 --resolve-addresses --overflow-block
--smpl-entries=2000000
--smpl-outfile=164.gzip-MEM_LOAD_RETIRED:L2_MISS-sampling --
/home/zhc/speccpu/bin/specinvoke -d
/home/zhc/speccpu/benchspec/CINT2000/164.gzip/run/00000020 -e speccmds.err
-o speccmds.out -f speccmds.cmd
Thanks.
