parallel option not supported in icc compiler

[Manoj_V_1]

Hi,

I have recently installed intel sytem studio trial version and integrated with eclipse. I tried to build my C code with  parallelization (-parallel) option, which is available at project properties-> C/C++ Build->Settings->Optimization. But, I am getting the command line remark as shown:

icc: command line remark #10148: option '-parallel' not supported

Please, let me know how to rectify this problem.

Regards,

Manoj

Hi Sukruth,

Thanks for looking into the issue. I am facing one more issue with using the cilk plus keywords into my C code but I am getting a build error. It is the same Intel System Studio trial version integrated with eclipse Indigo IDE.  Please, have a look into the code snippet below  and also the corresponding build error

#include "stdio.h"
#include "stdlib.h"
#ifndef __cilk
#include <cilk/cilk_stub.h>
#endif

#include <cilk/cilk.h>

void main()

{
  int a,b,c;
  int d[20],e[20];
  int k;
   a = 20, b= 30;
  c = a*b;
  for (k=0;k<20;k++)
    d=k;
 

cilk_for(k=0;k<20;k++)
  e = 2*d;
 }

Build Error Occurred:

undefined reference to `__cilkrts_cilk_for_32'

Looking forward to hear from you.

Regards,

Manoj

Hi Manoj,

               I was able to successfully build the sample that you have provided both in eclipse and command line. I am pasting the command line results here :-

Could you please try in the command line and let me know if you are facing the same issue?

How to set the compiler in commandline?

source /opt/intel/system_studio_2015.2.050/bin/compilervars.sh intel64
