lock-free singly linked list design
|
| |
I've been thinking about lock-free singly linked lists. I've had a thought or two. I will fall off my chair if any of this is original. What I would like however is to see what you guys think, since it's nicer to find mistakes *before* you've put in hours and hours of implementation work. Having looked somewhat at the literature, there seem to be a number of... more »

Avoiding atomic decrement in final ref counting release
|
| |
Hi, Is this correct implementation of COM style Release: void Release() { // no atomic if single owner release the object if (m_ref == 1 || atomic_decrement(&m_ref) == 0) { delete this; } ...Memory visibility is guaranteed by the synchronization used to acquire reference to the object.... more »

Race in boost::shared_ptr?
|
| |
Is it only me who thinks that there is a race? Here is a piece of code from boost_1_41_0\boost\smart_ptr\d etail \sp_counted_base_solaris.hpp, it implements simple reference counting with basic-thread safety: void release() // nothrow { if( atomic_dec_32_nv( &use_count_ ) == 0 ) {... more »

patients / licensing issues
|
| |
I'm trying to find out if there are patient/licensing issues involved in using Treiber's stack or Michael and Scott's queue. I understand the Boost library is using M&S's queue, so I'm guessing it's generally available. I can't find any info on T's stack. I'm also interesting in finding out about Harris' singly linked-list; I... more »
