OpenMP Tasks + Offload possible?

ds534486 — Wed, 19 Dec 2012 16:08:19 GMT

Hi,

when I offload a parallel region, my OpenMP tasks are not executed, is this intended?

The example below gives no output as it is, it seems the tasks are created but not executed. If I omit the offload or the task pragma, I get the expected result. Any idea what I am doing wrong?

Regards,

Dirk

Example:

int main(){

#pragma offload target(mic)

#pragma omp parallel

{

#pragma omp task

printf("Hello World!\n");

}

return 0;

}

You have not done anything wrong. There is currently a defect with using omp task inside an offload region that is expected to be fixed in the next update release tentatively scheduled for late January. I confirmed your program runs correctly with a newer (internal-only) build of the compiler.

Thanks for the information. I

Thanks for the information. I will wait for the compiler update then. Dirk
