Hi Intel team it's me again.
I would like to know how to parallelize this:
//#pragma acc parallel loop
for(i=0; i<targets; i++)
{
//#pragma acc loop
for(j=0; j<lines_samples; j++)
{
if(i == (targets-1)) x_p[i*lines_samples+j] = 0;
u[i] += pow(x_p[i*lines_samples+j], 2);
}
if(sum1 < u[i]) sum1 = u[i]; // Does this make it unparallelizable?
}
The problem is that last line. I tried to parallelize it like this:
my_queue.submit([&](auto &h) {
h.parallel_for(sycl::range<2>(targets,lines_samples), [=](auto index) {
int i = index[0];
int j = index[1];
if(i == (targets-1)) x_p[i*lines_samples+j] = 0;
u[i] += pow(x_p[i*lines_samples+j], 2);
});
}).wait();
But as you can see, I don't know where to put that last line so the behaviour is the same. That line is supposed to be executed only once per i iteration.
Looking forward to your answer.
Thank you!
