Installing and Managing the Sampling Driver on an Intel® Xeon Phi™ Coprocessor Card

For hardware event-based sampling analysis on an Intel® Xeon Phi™ coprocessor based on Intel Many Integrated Core (Intel MIC) architecture, a sampling driver should be installed on the coprocessor cards to be sampled. Typically, the VTune Amplifier installs the drivers by default during product installation. If for some reasons the sampling driver was not properly installed on the Intel Xeon Phi coprocessor card(s), you may need to install the driver manually.

To install the sampling driver manually, run the following command lines:

1. Copy the install files to a system location:

   $ sep_micboot_install.cmd

2. Start (or restart) the Intel Xeon Phi coprocessor service (this also restarts the sampling driver once the files are copied in the previous step):

   $ net start mpss

   $ micctrl -w

To uninstall the sampling server and driver on systems with the micboot-enabled Intel MPSS, run the following commands as root or under sudo:

$ net stop mpss
$ sep_micboot_uninstall.cmd
$ net start mpss
$ micctrl –w
