Hi @ll:
I just hacked the runspec of SPEC to automatically run pfmon to collect
counting information and sampling information.
However, I can correctly counting information in counting mode of pfmon,
with --follow-all, but failed in sampling mode of pmon.
[EMAIL PROTECTED] speccpu]$ pfmon --follow-all --aggregate-results -e
BUS_TRANS_BURST:ALL_AGENTS:BOTH_CORES --no-cmd-output --with-header
--short-smpl-periods=20011 --long-smpl-periods=50021 --resolve-addresses
--overflow-block
--smpl-outfile=run-BUS_TRANS_BURST:ALL_AGENTS:BOTH_CORES-sampling --
/home/zhc/speccpu/bin/specinvoke -d
/home/zhc/speccpu/benchspec/CINT2000/164.gzip/run/00000019 -e speccmds.err
-o speccmds.out -f speccmds.cmd
unknown ptrace event 0
Not enough memory to create perfmon context for [10126],
check your locked memory resource limit with limit or ulimit
session terminated by unrecoverable error
After remover the option --follow-all, pfmon can perform correctly, but
the result sampling file is NULL.
[EMAIL PROTECTED] speccpu]$ pfmon --aggregate-results -e
BUS_TRANS_BURST:ALL_AGENTS:BOTH_CORES --no-cmd-output --with-header
--short-smpl-periods=20011 --long-smpl-periods=50021 --resolve-addresses
--overflow-block
--smpl-outfile=run-BUS_TRANS_BURST:ALL_AGENTS:BOTH_CORES-sampling --
/home/zhc/speccpu/bin/specinvoke -d
/home/zhc/speccpu/benchspec/CINT2000/164.gzip/run/00000019 -e speccmds.err
-o speccmds.out -f speccmds.cmd
Why I must use -follow-all is because that each SPEC benchmark is
triggered by /home/zhc/speccpu/bin/specinvoke, otherwise, pfmon just can
collect the PMU information of specinvoke.
Thanks for the incoming suggestions.
