OpenMP 4.0 implementation in Intel Compiler

[Rezaul_R_]

Hi..

CAN YOU PLEASE TELL ME, WHICH INTEL COMPILER VERSION HAS IMPLEMENT OPENMP 4.0 DIRECTIVES ..? 

I am trying to execute openmp 4 (#pragma omp target data  map.. / #pragma omp target) ---> I am using icc (ICC) 15.0.2 20150121 on stampede, but not able to compile. [goal is to compare 1 & 2]

< login2.stampede(197)$ icc -openmp omp_target_cost_offload.c -mmic -o ompTarget_cost_offload

omp_target_cost_offload.c(44): warning #3180: unrecognized OpenMP #pragma

  #pragma omp target data  map(to: a[0:size], b[0:size])  map(from: c[0:size])

          ^

omp_target_cost_offload.c(46): warning #3180: unrecognized OpenMP #pragma

    #pragma omp target >

and the code is simple as: 

#pragma omp target data  map(to: a[0:size], b[0:size])  map(from: c[0:size])

{

        #pragma omp target 

        #pragma omp parallel for default(none) shared(a,b,c,size)

        for ( i = 0; i < size; ++i)

            c = a + b;

}

THANK YOU VERY MUCH IN ADVANCE.

You are compiling to generate a XEON PHI native code.  If you want to use the offload model in OpenMP  remove the -mmic option
