SPEC CPU2006
安裝 SPEC
It is generally not possible to do cross-compilation of Perl, as Perl's build process involves running binaries generated during the build. Therefore, getting a toolset onto an embedded platform without a native compiler is most likely impossible. 1.c. When to build the tools yourself http://www.spec.org/cpu2006/docs/tools-build.html#when2build
- SPEC 會用到的工具缺少 ARM 的 binary。建議使用 QEMU。或是採取另一種方法，請見
tools/src/perl-5.8.8/INSTALL，它有說明如何 cross compile。$ wget http://people.debian.org/~aurel32/qemu/armel/vmlinuz-2.6.32-5-versatile $ wget http://people.debian.org/~aurel32/qemu/armel/initrd.img-2.6.32-5-versatile $ wget http://people.debian.org/~aurel32/qemu/armel/debian_squeeze_armel_desktop.qcow2 $ wget http://people.debian.org/~aurel32/qemu/armel/debian_squeeze_armel_standard.qcow2 # root/root; user/user $ qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile \ -initrd initrd.img-2.6.32-5-versatile \ -hda debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1 console=ttyAMA0" -nographic
- 修正 SPEC 的問題。

- 安裝 SPEC 會用到的工具。或是以 NFS 掛上已編譯好的 SPEC1)。
$ apt-get update $ apt-get install gcc g++ gfortran automake # 避掉 "You haven't done a "make depend" yet" 的錯誤。 $ ln -sf /bin/bash /bin/sh # 預設可使用網路，可以透過網路取得 SPEC tarball; 又或是掛載 ISO 檔。 $ cd ${SRC}/tools/src $ ./build.sh
運行 SPEC
閱讀 SPEC CPU2006 Documentation、SPEC CPU2006 Config Files 和 The 'runspec' Command。
選項
–nobuild 可以避免重新編譯。
- 在 /data/Benchmarks/SPEC/CPU2006_v1.1_x86/config 底下生成一個設定檔。
$ cp Example-linux64-amd64-gcc43.cfg chenwj-i71-example.cfg
- 新增
qemu = /path/to/qemu-i38 curdir = /tmp/chenwj/spec # 測量結果放置處 output_root = ${curdir}/spec_results # summit 可以加上額外的指令及參數，預設為 $command submit = $qemu $command
- 建立軟連結，方便修改設定檔
$ cd /tmp/chenwj/spec $ ln -s /data/Benchmarks/SPEC/CPU2006_v1.1_x86/config/chenwj-i71-example.cfg . $ cd /data/Benchmarks/SPEC/CPU2006_v1.1_x86 # 這樣才抓得到 runspec $ . shrc $ cd /tmp/chenwj/spec $ runspec --config=chenwj-i71-example.cfg --iterations=1 --size=test mcf
- 中止測量Ctrl+Z
$ pstree -p | grep runspec -A2 -B2 $ killall
若要同時執行多個 benchmark，請手動並將其至於背景執行。
declare -a benchmark=( "400.perlbench" "401.bzip2" "403.gcc" "410.bwaves" "416.gamess" "429.mcf" "433.milc" "434.zeusmp" "435.gromacs" "436.cactusADM" "437.leslie3d" "444.namd" "445.gobmk" "447.dealII" "450.soplex" "453.povray" "454.calculix" "456.hmmer" "458.sjeng" "459.GemsFDTD" "462.libquantum" "464.h264ref" "465.tonto" "470.lbm" "471.omnetpp" "473.astar" "481.wrf" "482.sphinx3" "483.xalancbmk" "998.specrand" "999.specrand" ) for bench in "${benchmark[@]}"; do runspec --config=${CONFIG} --iterations=1 --size=test $bench done
Cross Compile
修改 CC 和 CXX 成 cross compiler。
$ runspec --config=chenwj-armv5.cfg --action=build --action setup all
SPEC Virt
需安裝 JDK，不建議安裝 GCJ。
$ apt-get install openjdk-6-jre $ java -jar setup.jar -i console # 修改設定檔以符合自身需求。 $ vi /opt/SPECvirt/Control.config
$ -net nic -net tap
