As an aside, Krow and I had a long chat today about the various
bottlenecks that can occur when trying to do atomic CAS operation on
multi-core machines. I'm very much hoping we can get your team's input
on scalable solutions to this problem...
Sorry for late response, Jay.
I have experimented a little with CAS on memcached, but nothing very
advanced, I am afraid...
With the memcached team, I worked on scalability issues on the Niagara
platform.
With the HADB team, we did some scalability work that involved mutexes
and condition variables, but never had the time to make a truly scalable
solution. One experience though was that in order to go from a single-
to a multi-thread architecture, defining and implementing clear
semantics in the code became even more important.
Thanks,
Roy
