The reason is IMHO, is that it is possible to have 0 LLC misses if the cac= he is large enough and code was run for enough iterations. I wasn't able to make the test fail for other reasons (I only tested non-ne= sted case so far, nested this test also fails sometimes) Best regards, Maxim Levitsky --=20 You may reply to this email to add a comment.
