Hi
You are correct, in X10 those critical sections would be unnecessarily
serialised. Only one lock is used per place, and each atomic section will
contend on that one lock.
If this causes a problem, you can use explicit locks (just like Java), or
you can use or write a lock-free datastructure. The classes you need are
found in x10.util.concurrent
There is a group experimenting with implementing X10 atomics with
transactional memory, but this work has only just begun.
Good luck :)
