Distributed Reader-Writer Mutex

A new article Distributed Reader-Writer Mutex describes design and implementation of a simple yet scalable rw mutex. The mutex uses an interesting technique of per-processor data. Results of a benchmark against plain pthread_rwlock_t are presented.

By the way, I've changed code license on the site, now all code is covered by the Simplified BSD License.

  2. @sbahra Yes, I am not describing anything new here. I am pretty sure that there is quite a few prior art related to distributed rw mutexes.
    However, I have some aces in the hole :) like asymmetric reader-writer mutexes. I co-authored a paper on it, however I'm not sure as whether it will make it into SPAA 2011 or not.

Still, ipconfig is useful because of its extensions. ipconfig /release followed by ipconfig /renew can force your Windows PC into asking for a new IP address, which is useful if your computer claims one isn't available. You can also use ipconfig /flushdns to refresh your DNS address. These commands are great if the Windows network troubleshooter chokes, which does happen on occasion.
