lmbench-1 编译和运行

目录

https://github.com/intel/lmbench

编译

安装依赖：

yum install -y libtirpc libtirpc-devel

修改scripts/build脚本，在LDLIBS=-lm下面添加两行：

LDLIBS="${LDLIBS} -ltirpc"
CFLAGS="${CFLAGS} -I/usr/include/tirpc"

运行

make results # 首先会执行交互式配置，配置文件生成并保存于 ./bin/$OS/CONFIG.xxx
             # 内存可选则小一点，send mail选择no
             # 随后进行测试，执行较久
             # 所有都执行的话，执行内容较多 可以直接cd src && make hardware 仅测试硬件
make see     # 查看报告

过程分析

执行过程分析:

results: lmbench
        @env OS="${OS}" ../scripts/config-run # 配置文件生成于 ./bin/$OS/CONFIG.xxx
        @env OS="${OS}" ../scripts/results

scripts/results:

. ../bin/$OS/$CONFIG
...
RESULTS=results/$OS/xxx # 了解测试进度可以通过tail 这个文件进行了解
...
./lmbench $CONFIG 2>../${RESULTS}

. ../bin/x86_64-linux-gnu/CONFIG.localhost.localdomain
# bash -x ./lmbench CONFIG.localhost.localdomain 2> my.log 这一步其实就是lmbench脚本调用`./bin/`下的可执行文件去执行
