Dear List,
I meet a problem about memory release in x10 code as below shows. I
try to read many large files step by step, as 5 times in the code. For
each step, the DistArray is initialized firstly, and then reading the
strings at each place. The problem is that: after the first step, when
K==2, I observed that the memory usage does not decrease, and so do
the following steps. It leads the program failed at last for that all
the memory has gone.
So it means that the contents of Read(place) in the previous step
still exist in the memory, even when the DistArray has been
initialized. Is there any method to solve this problem?
Thanks a lot!
Long
val N:Int=Place.MAX_PLACES;
for (var K:int=0;K<5;K++){
val r:Region=0..(N-1);
val d:Dist=Dist.makeBlock(r);
val Read=DistArray.make[ArrayBuilder[String]](d);
finish for( p in Read.dist.places()) {
at (p) async {
Read(here.id)=new ArrayBuilder[String]();
}
}
finish for( p in Place.places()){
at (p) async {
Read(here.id).add(MANY STRINGS)
//processing the strings in Read(here.id);
}
}
} //end for K
