This example uses the same code, but in this case the kernel is configured to be restart and run for three iterations and then stop. The only required change is to specify the number of iterations as shown in the code example below.

Tip: In the counted auto-restart case, there is no need to use the abort(), because the host will know when to stop.
143   xrt::kernel incr(device, uuid, "increment");
144   int adder1 = 20;  // arbitrarily chosen to be different from 0
145   int adder2 = 10;  // arbitrarily chosen to be different from 0
151   // start the incr kernel in auto restart mode with default adders
152   // since it is a streaming kernel it will be stalled waiting for
153   // input
154   auto incr_run = incr(xrt::autostart{3}, nullptr, nullptr, adder1);
