I tried the method workerId() in the class Runtime. Then,
I found several activities made by async were ran per 1
worker.
So, why did you make it public about worker, but private
about activities?
What I said below. The language spec does not require that
activities be named at runtime, deliberately. For example, this
supports the idea that the compiler might actually eliminate an
activity at compile-time, merging it into a surrounding activity.
It is of course possible to design this differently, and
distinguish, for instance, between "potential runtime activities"
and "actual runtime activities". For now, it would make sense for
you to implement what you need to implement at the X10 source level,
and see how this works out.
For instance, wherever u create an activity u could instead create
an instance of a new class you define, called Activity, and pass it
the code, e.g. instead of
async {
x.m();
y.inc();
}
you would call
new Activity(()=> { x.m(); y.inc();}).run();
and define Activity thus:
class Activity(f: ()=>void) {
public def run() {
async f();
}
}
Now you can add whatever code you want to add to Activity, e.g. add
whatever meta data you want as fields. Make the activity be a
GlobalRef so u can address it from any place.
Similarly you can "virtualize" Finish, through your own Finish
class, and keep track of meta-data of interest to you through your
own Finish class etc.
