which freezes its m next reference The m_next reference then becomes the cur rent node and is locked At this point, both the predecessor and next node are frozen, allowing us to insert before or after the current node or remove the cur rent node By using E q u a l ityCompa r e r < T > Defa u lt E q u a l s, we determine whether we have found the element we're searching for and, if so, we invoke the action delegate, exit the locks, and return t rue Otherwise, we continue the search This entails releasing the lock on the predecessor, setting predecessor to the current, and continuing Eventually, if we fail to find a matching ele ment, we must remember to exit the predecessor lock The drawback to this approach of course is that it requires O(N) lock acquisitions to find an element We could perform an optimization by using optimistic concurrency If we avoided taking locks until we found an ele ment of interest, we would substantially reduce the number of locks acquired during the search This requires that we restart our search, how ever, if we find that something has gone awry in the meantime

Notice that we defer locking until we've found a matching element Once this happens, we acquire locks on both the predecessor and the cur rent element, and, before invoking the action, verify that pred m_n ext still points at c u r r o If not, we break out and continue around the outer loop; this restarts the search back at the beginning of the list A reasonable imple mentation might be to fall back to the pessimistic routine (shown earlier) if one failure was reached; this prevents too many restarted attempts and wasted work For lengthy lists this will save time spent retraversing nodes and will ensure the worst case is still O(N) This is the already the best case for the pessimistic approach

Dictionary (Hashtable) Building an efficient hash table based dictionary is no easy task STL offers ha sh_m a p and NET offers its old System C o l l e c t i o n s H a s ht a b l e and new S y s t e m C o l l e c t i o n s G e n e r i c D i c t i o n a ry < TKey , TVa l u e > types for this purpose When it comes to building a concurrent one, there are several algorithms from the research community that build on top of lock free sets and linked lists Most of them tend to be very expensive in terms of the number of CAS operations incurred for simple operations such as adding, searching, and deleting For modern Intel and AMD architectures, such algorithms tend not to perform too greatly; and, moreover, the implemen tations are incredibly complex That said, they are worth understanding from a pure educational standpoint: refer to one of the papers referenced at the end of the chapter (see Further Reading, Michael, Scott, Purcell, Har ris) if you are interested It's relatively straightforward to build a hashtable that provides two properties
