lmbench工具的自动化测试实现

底层测试测试工具开发

一 概述

Lmbench是个多平台软件，因此能够对同级别的系统进行比较测试，反映不同系统的优劣势，可用于评价系统综合性能的多平台开源benchmark，能够测试包括文档读写、内存操作、进程创建销毁开销、网络等性能，测试方法简单。通过选择不同的库函数我们就能够比较库函数的性能；更为重要的是，作为一个开源软件，lmbench提供一个测试框架，假如测试者对测试项目有更高的测试需要，能够通过少量的修改源代码达到目的。测试系统调用时间，shell命令启动时间，系统信号处理时间，上下文切换性能等。

二 测试前提

  • 需要安装依赖
yum install -y gcc gcc-c++ libtirpc-devel
  • 获取源码包
wget https://nchc.dl.sourceforge.net/project/lmbench/development/lmbench-3.0-a9/lmbench-3.0-a9.tgz

三 测试步骤

  • 解压lmbench3源码包以后cd 切换到lmbench源码目录
  • 修改scripts/build脚本，在LDLIBS=-lm下面添加LDLIBS="${LDLIBS} -ltirpc"              CFLAGS="${CFLAGS} -I/usr/include/tirpc"两行
  • 修改scripts/gnu-os脚本，将165、173、830行的arm*改为aarch64*
  • 执行make OS=x86 results/make OS=arm64 results测试，并在测试完成后make see查看测试结果，Lmbench测试成功并在results下生成summary.out的测试结果

四 自动化测试

  • 安装的代码片段
       ...
        if ENV.osName() in ['ctyunos', 'openeuler']:
            # LDLIBS = "${LDLIBS} -ltirpc"
            # CFLAGS = "${CFLAGS} -I/usr/include/tirpc"
            host.run(f"""cd {cls.unzip_path}; sed -i "s/-lm/\\"\\${'{LDLIBS}'} -ltirpc\\"\\nCFLAGS=\\"\\${'{CFLAGS}'} -I\\/usr\\/include\\/tirpc\\"/g" scripts/build""")
        if ENV.get_gcc_version() == '7.3.0':
            sed_cmd = """sed -i "s/llseek/lseek64/g" ./src/disk.c"""
            host.run(f"cd {cls.unzip_path};{sed_cmd}")
        cls.arch = ENV.get_arch()
        if cls.arch == 'aarch64':
            host.run(f"cd {cls.unzip_path};sed -i 's/arm\\*/aarch64\\*/' scripts/gnu-os")
        ...
  • 在进行测试前需要进行配置，以配置测试参数以及获取测试环境的信息(如测试size、cpu频率等等)，配置脚本在 lmbench3/scripts 目录下，名字叫config-run。在lmbench目录下，执行make results，根据屏幕提示，输入的内容会生成测试配置文件，在bin/{arch}/CONFIG.{hostname}

在需要测试的benchmark项填入yes即可

  • 编译成功后，在bin/{arch}/目录下会一个lmbench的执行文件，测试具体的lmbench测试项，只需在lmbench执行文件后接对应的benchmark配置文件。如./lmbench file.conf，测试结果如下

lmbench工具的自动化测试实现

底层测试测试工具开发

一 概述

Lmbench是个多平台软件，因此能够对同级别的系统进行比较测试，反映不同系统的优劣势，可用于评价系统综合性能的多平台开源benchmark，能够测试包括文档读写、内存操作、进程创建销毁开销、网络等性能，测试方法简单。通过选择不同的库函数我们就能够比较库函数的性能；更为重要的是，作为一个开源软件，lmbench提供一个测试框架，假如测试者对测试项目有更高的测试需要，能够通过少量的修改源代码达到目的。测试系统调用时间，shell命令启动时间，系统信号处理时间，上下文切换性能等。

二 测试前提

  • 需要安装依赖
yum install -y gcc gcc-c++ libtirpc-devel
  • 获取源码包
wget https://nchc.dl.sourceforge.net/project/lmbench/development/lmbench-3.0-a9/lmbench-3.0-a9.tgz

三 测试步骤

  • 解压lmbench3源码包以后cd 切换到lmbench源码目录
  • 修改scripts/build脚本，在LDLIBS=-lm下面添加LDLIBS="${LDLIBS} -ltirpc"              CFLAGS="${CFLAGS} -I/usr/include/tirpc"两行
  • 修改scripts/gnu-os脚本，将165、173、830行的arm*改为aarch64*
  • 执行make OS=x86 results/make OS=arm64 results测试，并在测试完成后make see查看测试结果，Lmbench测试成功并在results下生成summary.out的测试结果

四 自动化测试

  • 安装的代码片段
       ...
        if ENV.osName() in ['ctyunos', 'openeuler']:
            # LDLIBS = "${LDLIBS} -ltirpc"
            # CFLAGS = "${CFLAGS} -I/usr/include/tirpc"
            host.run(f"""cd {cls.unzip_path}; sed -i "s/-lm/\\"\\${'{LDLIBS}'} -ltirpc\\"\\nCFLAGS=\\"\\${'{CFLAGS}'} -I\\/usr\\/include\\/tirpc\\"/g" scripts/build""")
        if ENV.get_gcc_version() == '7.3.0':
            sed_cmd = """sed -i "s/llseek/lseek64/g" ./src/disk.c"""
            host.run(f"cd {cls.unzip_path};{sed_cmd}")
        cls.arch = ENV.get_arch()
        if cls.arch == 'aarch64':
            host.run(f"cd {cls.unzip_path};sed -i 's/arm\\*/aarch64\\*/' scripts/gnu-os")
        ...
  • 在进行测试前需要进行配置，以配置测试参数以及获取测试环境的信息(如测试size、cpu频率等等)，配置脚本在 lmbench3/scripts 目录下，名字叫config-run。在lmbench目录下，执行make results，根据屏幕提示，输入的内容会生成测试配置文件，在bin/{arch}/CONFIG.{hostname}

BENCHMARK_CONNECT=
BENCHMARK_RPC=
BENCHMARK_HTTP=
BENCHMARK_BCOPY=

在需要测试的benchmark项填入yes即可

  • 编译成功后，在bin/{arch}/目录下会一个lmbench的执行文件，测试具体的lmbench测试项，只需在lmbench执行文件后接对应的benchmark配置文件。如./lmbench file.conf，测试结果如下
