Install the Sampling Drivers for Windows* Targets

To install the drivers on Windows* 7 (deprecated) and Windows* Server 2008 R2 operating systems, you must enable the SHA-2 code signing support for these systems by applying Microsoft Security update 3033929. If the security update is not installed, event-based sampling analysis types will not work properly on your system.
To verify the sampling driver is installed correctly on a Microsoft Windows* OS, open the command prompt as an administrator and run the
amplxe-sepreg.exe
 utility located at
<>\bin32
.
To make sure your system meets all the requirements necessary for the hardware event-based sampling collection, enter:
amplxe-sepreg.exe -c
This command performs the following dependency checks required to install the sampling driver:
  • platform, architecture, and OS environment
  • availability of the sampling driver binaries:
    sepdrv4_x.sys
    ,
    socperf2_x.sys
    , and
    sepdal.sys
  • administrative privileges
  • 32/64-bit installation
To check whether the sampling driver is loaded, enter:
amplxe-sepreg.exe -s
If the sampling driver is not installed but the system is supported by the
VTune
Profiler
, execute the following command with the administrative privileges to install the driver:
amplxe-sepreg.exe -i

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
