Detailed Description

This class is used to check for errors in kernels. It is composed of a buffer of u32 that is used to store the error counts.

The class provides a method to count errors for multiple flags. The flags are set by doing a fetch add operation on the corresponding element of the buffer. The element is chosen by the argument of the set_error method. The value of the element is incremented by 1 each time the set_error method is called.

auto sched = shamsys::instance::get_compute_scheduler_ptr();
 
shamalgs::atomic::ErrorCheckCounter error_util(sched, 3);
 
sham::kernel_call(
    sched->get_queue(),
    sham::MultiRef{},
    sham::MultiRef{error_util},
    100,
    [](u32 i, auto error_util) {
        if (i == 2) {
            error_util.set_error(0);
        }
        if (i == 23 || i == 101) {
            error_util.set_error(1);
        }
    });
 
auto precondition_error = error_util.get_outputs();
