| Sky89 <Sky89@sky68.com>: May 05 08:00PM -0400 Hello.. Here is also the truth about Lockfree algorithms, here is what said Martin Thompson: "In my experience of teaching and developing lock-free algorithms, not only do they provide significant throughput advantages as evidenced here, they also provide much lower and less variance in latency."

This paper suggests a simple solution to this problem. We show that, for a large class of lock- free algorithms, under scheduling conditions which approximate those found in commercial hardware architectures, lock-free algorithms behave as if they are wait-free. In other words, programmers can keep on designing simple lock-free algorithms instead of complex wait-free ones, and in practice, they will get wait-free progress.
