// This tests the level zero plugin's kernel dynamic batch size adjustment

// It starts out by enqueing 40 kernels before it does a wait, and it does
// this 5 times. That should cause the dynamic batch size adjustment to
// raise the batch size up several times.
// raise the batch size up 3 times.
//
// Then the test starts enqueueing only 4 kernels before doing a wait, and
// it does that 5 times as well. That should cause the batch size to
// be lowered, just once to be less than 4.
