System information

Intel® Xeon Phi™ Coprocessor DEVELOPER’S QUICK START GUIDE

coprocessor were installed, it would be called “mic1” and located at 172.31.2.1, and it would see the host

as 172.31.2.254.

For detailed information on setting up the card for non-root users, adjusting the network configuration,

mounting an NFS file system exported by the host for use on the Intel® Xeon Phi™ coprocessor, etc., please

see the document Intel® MPSS Boot Configuration Guide.

Useful Administrative Tools

This product ships with the following administrative tools, found in the “/opt/intel/mic/bin” directory.

Root, and users needing to use these tools, should add this directory to their default path:

 micinfo - provides information about host and coprocessor system configuration.

 micflash - updates the flash on the coprocessor; saves and retrieves the version and other

information for each section of the flash

 micsmc - a tool designed to ease the burden of monitoring and managing Intel® Xeon Phi™

coprocessors.

 miccheck – a utility for verifying the configuration of an Intel® Xeon Phi™ coprocessor by running

various diagnostic tests.

 micnativeloadex – a utility that will copy an Intel® MIC Architecture native binary to a specified Intel®

Xeon Phi™ coprocessor r and execute it

 micctrl – a tool to help the system administrator configure and restart the coprocessor

 micrasd – an application running on the host to handle and log hardware errors.

 mpssflash – the POSIX version of micflash.

 mpssinfo – the POSIX version of micinfo.

Please see section 8 in the MPSS readme.txt for details on these tools and their arguments.

Getting Started/Developing Intel® Xeon Phi™ Software

You develop applications for the Intel® MIC Architecture using your existing knowledge of multi-core and SIMD

programming. The offload language extensions allow you to port sections of your code (written in C/C++ or

FORTRAN) to run on the Intel® Xeon Phi™ Coprocessor, or you can port your entire application to the Intel® MIC

Architecture. Best performance will only be attained with highly parallel applications that also use SIMD

operations (generated by the compiler or using compiler intrinsics) for most of their execution.

Available Software Development Tools / Environments

You can start programming for the Intel® Xeon Phi™ Coprocessor using your existing parallel programming

knowledge and the same techniques you use to develop parallel applications on the host. New tools were not

created to support development directly on the Intel® Xeon Phi™ Coprocessor; rather, the familiar host-based

Intel tools have been extended to add support for the Intel® MIC Architecture via a few additions to standard

languages and APIs. However, to make best use of the development tools and to get best performance from

the Intel® Xeon Phi™ Coprocessor, it is important to understand the Intel® MIC Architecture.
