Hi, My application happens to write messages on stderr. GEM5 (latest stable release) runs very slow if errout (for stderr redirection) option is specified on the command line. The following are the gem5 commands and their times without and with errout option to gem5.
Without errout (stderr is printed on terminal): ~/gem5-clean/gem5-stable/build/ARM/gem5.fast --outdir=./ ~/gem5-clean/gem5-stable/configs/example/se.py --cmd=mp3dec/mp3dec.m5arm --options="-v mp3dec/input1/small.mp3 --output=wave:out" --output=result.out.input1 14.76user 0.16system 0:17.56elapsed 84%CPU With errout: ~/gem5-clean/gem5-stable/build/ARM/gem5.fast --outdir=./ ~/gem5-clean/gem5-stable/configs/example/se.py --cmd=mp3dec/mp3dec.m5arm --options="-v mp3dec/input1/small.mp3 --output=wave:out" --output=result.out.input1 --errout=result.err.input1 25.43user 1.57system 13:29.44elapsed 3%CPU Does anyone know why this is happening? Thanks a lot Daya
