Thanks, Eranian.I have switched to root, that problem is gone.
Another issue is about pebs mode, which seems is not supported, why?
[EMAIL PROTECTED] speccpu]# 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-outfile=run-MEM_LOAD_RETIRED:L2_MISS-sampling --
/home/zhc/speccpu/bin/specinvoke -d
/home/zhc/speccpu/benchspec/CINT2000/175.vpr/run/00000004 -e speccmds.err -o
speccmds.out -f speccmds.cmd
cannot find requested kernel sampling format : pebs_core
Thanks.
