Hello.....


You have seen me in my previous post reasonning about Trasactional memory..

But there is still another big problem with Transactional memory..

The problem is with realtime critical systems, to be able
to use Transactional memory in realtime crtitical systems, you
have to be able to calculate precisely the latency and the throghuput,
but since in transactional memory you can get conflicts that can
get you in the worst case performances that are not good, so
transactional memory is not best suited for realtime critical systems
that wants to optimise more the performance and guaranty a scaling that
is decent, so here comes again the way of locks that can get you a more
decent performance with a more predictable performance that scales more,
so locks are best suited for realtime critical systems when the
characteristic of performance is taken alone.



Thank you,
