Hi Kevin,
The "at" construct is the primary X10 language construct for cross
place communication. It is implemented using one-sided communication.
There are some library constructs (x10.util.Team;
x10.array.Array.asyncCopy) that also use one-sided communication in their
internal implementation.
All of X10's communication is implemented on top of X10RT (
http://x10-lang.org/documentation/practical-x10-programming/x10rt-implementations.html)
which mainly provides active messages (one-sided communication).
