1)Your application details.

  code fragment such as below.

 

void __attribute__((noinline)) MatrixMulOpenMpGpuOffloading ()
{
int i, j, k;

// a is identity matrix
for (i=0; i<M; i++)
for (j=0; j<N; j++)
a[i][j] = 1.0;

// each column of b is the sequence 1,2,...,N
for (i=0; i<N; i++)
for (j=0; j<P; j++)
b[i][j] = i+1.;

// c is initialized to zero
for (i=0; i<M; i++)
for (j=0; j<P; j++)
c[i][j] = 0;

auto t1 = chrono::steady_clock::now();

for (int i = 0 ; i < 1000; i++)
{

// Parallelize on target device
#pragma omp target teams distribute parallel for simd map(to: a, b) map(tofrom: c) //thread_limit(128)
{
for (i=0; i<M; i++) {
// Each element of the product is just the sum 1+2+...+n
for (j=0; j<P; j++) {
for (k=0; k<N; k++) {
c[i][j] += a[i][k] * b[k][j];
}
}
}
}
}
auto t2 = chrono::steady_clock::now();

cout << "matmul default takes :" << chrono::duration_cast<chrono::microseconds>(t2 - t1).count() / 1000 << "us" << std::endl;


}

 

2)Commands used.

 

vtune -collect gpu-hotspot 

 

3)How the results are being viewed(CLI or GUI)

Hi Leevan,

 

Thanks for your patience. We tried running samples in devcloud where we are able to get the information related to computing task.Looks like the issue is related to your code as the information was not visible while running your code.Could you please try with some other samples ?
