OpenMP pragma: omp smid not recognized by dpcpp

[Tomasoni]

Hello all.

dpcpp compiler is warning me about a missing omp directive

```

matrixLib.c:395:14: error: expected an OpenMP directive
#pragma omp smid
^

```

in the following code

```

...

#pragma omp smid
for(int i=start; i<=end ; i += step)
   out_vector[midx++] = i;

```

But I read here

https://www.intel.com/content/www/us/en/develop/documentation/oneapi-dpcpp-cpp-compiler-dev-guide-and-reference/top/optimization-and-programming/openmp-support/openmp-pragmas.html

that omp smid directive is supported.

this works if compiled with gcc-9 or g++-9

Can you explain me what is the right directive with dpcpp?

Thanks

Hi,

Thanks for posting in Intel Communities.

Could you please try using the 'pragma omp simd' since it is a supported directive with the dpcpp compiler? Please find the below link:

We have tried a sample code and it worked without any errors. Please find the below screenshot:

Could you please elaborate on how to use 'pragma omp smid'?

And also, could you please let us know the Intel DPCPP compiler version, OS details, and sample reproducer code to investigate more on your issue?

Thanks & Regards,

Hello, thank you for your answer. I think I was missing `-qopenmp` while compiling with dscpp

I couldn't find this in the docs.

Thank you!
