Is there a web site anywhere with a list of open source resources for Fri, 05 Jun 2009 19:03:06 GMT Maurice Herlihy http://tech.groups.yahoo.com/group/liblf-dev/message/297 http://tech.groups.yahoo.com/group/liblf-dev/message/297 Multicore Programming [6.05s] C.

Thank you , Chris . Sorry for my poor english , I will try my best to express my own opinion . It is true that I don't use any memory barriers in my Thu, 26 Mar 2009 11:13:43 GMT Chris Purcell http://tech.groups.yahoo.com/group/liblf-dev/message/293 http://tech.groups.yahoo.com/group/liblf-dev/message/293 There don't appear to be any memory barriers in your code. How are you avoiding the issue of out-of-order execution on multiprocessor machines?

I've read so many citations, and other theories about ring buffers and memory barriers. But to me they're useless until someone can write a piece of code Sat, 01 Nov 2008 06:17:13 GMT Stephen Sinclair http://tech.groups.yahoo.com/group/liblf-dev/message/288 http://tech.groups.yahoo.com/group/liblf-dev/message/288 ...

I'd be surprised if gcc inserts any memory barriers. But I do remember reading somewhere that a C optimizer probably won't reorder Fri, 31 Oct 2008 14:34:12 GMT Bjorn Roche http://tech.groups.yahoo.com/group/liblf-dev/message/286 http://tech.groups.yahoo.com/group/liblf-dev/message/286 ... I can't find a citation right now, so I could be wrong. If I am wrong, sorry about that. It's obviously not behavior to count on anway, since even if you
