Dear Yoav,
Thank you for your concern, here's the simple code I used:
*
public class Hello
{
public static def main(var args: Rail[String]!) {
val h = new Hello();
val R:Region= [0..10];
val D:Dist(1)=Dist.makeBlock(R);
val a :DistArray[int](1) =DistArray.make[int](D, ((i):Point)=>i);
Console.OUT.println("NUm of children " +Place.numChildren(here.id));
finish ateach((i):Point in a.dist())
{
h.myPrint(a,i);
}
}
public static def myPrint(a:DistArray[int](1),i:Int)
{
Console.OUT.println("a("+i+"): " +a(i)+" at Place: "+here.id);
}
}*
So basically if I removed the static keyword in the method, and I ran the
application over only one process, it works just fine,
but if I increase the number of processes, for example 2 processes,
it would print those at place 0 but when it tries to print those at place 1
it gives me the following exception
*Uncaught exception at place 0: x10.lang.MultipleExceptions (home==1)
x10.lang.ClassCastException (home==1): Hello{self.home==here}
at x10::lang::Throwable::fillInStackTrace()
at x10aux::throwException(x10aux::ref<x10::lang::Throwable>)
at Hello__closure__2::apply()
at x10::lang::Activity::run()
at x10_lang_Runtime__Worker__closure__0::apply()
at x10::lang::Runtime::runAtLocal(int,
x10aux::ref<x10::lang::VoidFun_0_0>)
at
x10::lang::Runtime__Worker::loop(x10aux::ref<x10::lang::Runtime__Latch>,
bool)
at x10::lang::Runtime__Worker::apply()
at x10_lang_Runtime__Pool__closure__0::apply()
at x10::lang::Thread::thread_start_routine(void*)
at GC_inner_start_routine
at GC_call_with_stack_base
at GC_start_routine
at
at clone
*I think* *because place 1 is trying to access the method which is at place
0, am I correct?
Thank you again.
