How to compile C code for Xeon Phi (Windows 10)

I'm starting to work with a Xeon Phi and I'm stuck trying to compile a simple C program to run it on the coprocessor. I've tried using icl and icc commands but I haven't got any luck.

1.- with icl

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2018\windows\bin\intel64>icl test.c -o test.mic
Intel(R) C++ Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 18.0.2.185 Build 20180210

test.c
Microsoft (R) Incremental Linker Version 14.15.26726.0

-out:test.mic
test.obj

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2018\windows\bin\intel64>

then I tried to run test.mic on the Xeon Phi

[xeon@mic0 ~]$ ./test.mic
-sh: ./test.mic: cannot execute binary file
[xeon@mic0 ~]$

2.- with icc 

C:\Intel\cc_android_2018.2.185\bin\intel64>icc test.c -o test.mic

icc: error #10052: could not checkout FLEXlm license

I'm not sure about this error because I have the license.

Solution

  • The problem was the Intel Parallel Studio version I was using (Intel Parallel Studio 2018) . I downloaded Intel Parallel Studio 2017 Update 7 and the compilation worked. The command I was using:

    icl /Qmic test.c -o test.out

    And I was getting this error:

    icl: command line remark #10148: option '/Qmic' not supported
