vtune 使用pmc 时间的配置

Vtune的安装

下载parallel_studio_xe_2013_intel64.tgz

安装里面cl

/home/zxx/package/parallel_studio_xe_2013_intel64/amplifier_CLI_install

./install.sh

然后安装gui

rpm-i

intel-vtune-amplifier-xe-gui-243421-13.1-0.i486.rpm

intel-vtune-amplifier-xe-gui-243421-13.1-0.x86_64.rpm

intel-vtune-amplifier-xe-gui-common-243421-13.1-0.noarch.rpm

lsmod有的不会用正则表达式

sampingevents driver 配置参照下面的文档.

Installingthe Sampling Driver

Installing the samplingdriver may require using a development and target system:

• The development systemis the system you use to develop your application. This system hasfull binutils and a compiler.

• The target system is thesystem for which the application is targeted.

These are the steps forinstalling the Sampling driver:

1. Go to the /sepdksource directory:

   cd <install-dir>/sepdk/src

2. Build the samplingdriver.

   • For a target systemthat has full binutils and a compiler, run the following command.

     build-driver --ni--install-dir=../prebuilt

   • Fora target system that does not have full binutils and a compiler,you need to compile the driver on your development system, with thesettings for your target system:

     • Customizethe cc-sep3-driver script, includedin the installation, for your kernel, compiler and other systemsettings.
       See Customizingthe Driver Script for more information.

     • Runthe customized script to build the driver on your developmentsystem.

     • Copythe newly-built driver to the target system.

3. If the driver was builtsuccessfully, go to the directory where it was installed:

   cd<install-dir>/sepdk/prebuilt

4. To load the samplingdriver, use the following command:

   insmod-sep3 -r -g[user_group]

   where [user_group]is the name of the group that can perform sampling collection on thesystem.  To find which group you are a member of, run thecommand:

   groups

5. To have the systemautomatically load the sampling driver at boot time, run thefollowing command:

   boot-script -i -g[user_group]

6. To check whethersampling driver successfully loaded, run the command:

   insmod-sep3 -q

7. To unload the driver,use the command:

   rmmod-sep3

用命令行测试一下:

amplxe-cl-collect-with runsa -knobevent-config=CPU_CLK_UNHALTED.CORE,CPU_CLK_UNHALTED.REF,INST_RETIRED.ANY  YOURPROGRAM
