That depends on what input you intend to run bzip with. "speccmds.cmd" contains all commands to run a particular benchmark with a specific input. You can use a command from that file to run the benchmark+input combination you want to run (e.g. to run bzip with chicken.jpg, you will have to pass "chicken.jpg 30" as arguments to the bzip binary). what does these mean "-E , -c , -o" in the file speccmds.cmd? -e, -o are used to redirect the stdout and stderr of your benchmark run to particular files. should I use 6 input( input.source , chicken.jpg , liberty.jpg , > input.program , text.html , input.combined ) for running bzip2 on > gem5-fullsystem-arm or just use input.combined for input of bzip2? I think this really depends on what you are trying to study. Usually in papers, when authors present their data, they will mention the benchmark+input combination. Moreover, from SPEC's website: "401.bzip2's reference workload has six components: two small JPEG images, a program binary, some program source code in a tar file, an HTML file, and a "combined" file, which is representative of an archive that contains both highly compressible and not very compressible files." So you can pick an input which suits your experiments (or if you do not care, maybe the combined file makes the most sense). When I ran 401.bzip2 ,it finished after 10days. I need to know between > "429.mcf, 445.gobmk, > 456.hmmer,458.sjeng,462.libquantum,473.astar,483.xalancbmk > and 998.specrand"",Which one runs in 10 short days? I don't really remember the difference in execution times of these benchmarks (I think mcf, gobmk and sjeng will be faster than others, also it depends on which inputs are you using). I will suggest that you run these benchmarks on real hardware and see the difference in their execution times (you should see similar behavior on gem5 as well). and Is it not problem , if I use 4cores and cpu-type=DerivO3CPU for running > "spec cpu 2006" on gem5-fullsystem ? Running a complete benchmark might be too slow with DerivO3CPU. You can either use smaller inputs or run your benchmark for a smaller number of instructions. Moreover, I don't think 4 cores make sense with spec cpu 2006 benchmarks as they are single threaded workloads (obviously it also depends on what are you trying to study). For the last question, if I use sript file for running bzip2 on > gem5-fullsystem the following command, is it correct? Yes, that looks correct to me (assuming that the benchmark paths are correct). -Ayaz On Sun, Dec 20, 2020 at 8:01 AM FARIDEH ZIAEE <faridehzi...@gmail.com> wrote: > Hi > Thanks. > > > According to the SPEC website, I built and ran "spec cpu 2006" for "ref > and test input" by useing cross-compiling and qemu to chroot to an arm > linux image then I have traid to run "spec cpu 2006" on > gem5-fullsystem-arm. > > and you said "As far as I remember bzip binary inside run folder (the one > you referred to above) uses "data/all/input/input.combined" file by > default and the output you are seeing definitely shows that bzip ran with > input.combined." > ,does this mean that I have gone the right way and do I not need to > specify any arguments or input(ref,train) to run the "spec cpu 2006" on > gem5-fullsystem like what is said in the file "speccmds.cmd" that is in " > /home/farideh/mnt/benchspec/CPU2006/401.bzip2/run/run_base_ref_gcc43-64bit.0000 > "? > the file speccmds.cmd :: > > ""-C > /home/farideh/mnt/benchspec/CPU2006/401.bzip2/run/run_base_ref_gcc43-64bit.0000 > -o input.source.out -e input.source.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit input.source 280 > -o chicken.jpg.out -e chicken.jpg.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit chicken.jpg 30 > -o liberty.jpg.out -e liberty.jpg.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit liberty.jpg 30 > > > -o input.program.out -e input.program.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit input.program 280 > -o text.html.out -e text.html.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit text.html 280 > -o input.combined.out -e input.combined.err > ../run_base_ref_gcc43-64bit.0000/bzip2_base.gcc43-64bit input.combined 200"" > > what does these mean "-E , -c , -o" in the file speccmds.cmd? > > /////////////////////////////// > > According to the file ""speccmds.cmd"" in " > cpu2006/benchspec/CPU2006/401.bzip2/run/ run_base_ref_gcc43-64bit.0000", the > bzip2 built with 6 input( input.source , chicken.jpg , liberty.jpg , > input.program , text.html , input.combined ) , should I use 6 input( > input.source , chicken.jpg , liberty.jpg , input.program , text.html , > input.combined ) for running bzip2 on gem5-fullsystem-arm or just use > input.combined for input of bzip2? > > ///////////////// > > What arguments are usually used to implement the "spec cpu 2006" on > gem5-fullsysytem and how should they be used? > > > When I ran 401.bzip2 ,it finished after 10days.
