How to run submatrix function in serial?

[Esmail Abdul Fattah]

submatrix(output, 0,0, ind_x, ind_x) = serial(submatrix(input, 0,0, ind_x, ind_x));

 BLAZE_SERIAL_SECTION
{
    submatrix(output, 0,0, ind_x, ind_x) = submatrix(input, 0,0, ind_x, ind_x);
}

‌

Both of the above codes didn’t work. Thank you!

Hi Esmail!

We checked both code snippet in an OpenMP setting with 4 threads. In both cases the assignment was executed by exactly one thread. Therefore both examples work as expected.

Could you please be more specific about what doesn’t work? A minimum example with compilation flags and environment settings would help to analyse whether there is a problem. Thanks,

Best regards,

Klaus!
