They're into KCSS (k compare, single swap) IIRC, they used DWCAS to implement KCSS. I believe it had a lot of atomic operations under the hood, both ROP and KCSS; better off using an optimized mutex? ;) > and transactional > memory for obstruction-free (not lock-free) algorithms. http://groups.google.com/group/comp.programming.threads/msg/e43fce88eb0775c8 Does "obstruction-free" rely on backoff algorithms in order to avoid live-lock? BTW, How are they managing the memory for all of that... Do they use Java GC? . 0
