Neil and others, It might be interesting to look at some of the papers by Michael Scott et al. I am not an expert on non-blocking data structures, but the following page seems interesting:
http://www.cs.rochester.edu/u/scott/synchronization/ esp. "(7) nonblocking "dual" data structures, which combine lock freedom with condition synchronization; and (8) contention management for software transactional memory" In any case, I think only when contention is high the non-blocking algorithms are worth looking at. So can someone shine some light on where the contention might be? Cheers! -Min On Tue, 25 Jan 2005 Neil Conway wrote : > On Mon, 2005-01-24 at 16:50 -0700, Jonah H.
