Hello all,
I am trying to monitor the message send/receive between each place
with X10_TRACE_RXTX for my codes, but it seems there is something
wrong with the profiling results that: The RX bytes/TX bytes recorded
by the network card is total different from that recorded by
X10_TRACE_RXTX. In my test, the RX bytes/TX bytes recorded by the
network card of a node (testing with multi-nodes) is about 2GB, but
X10RT_RXTX shows only about 3MB per place (there are 12 places on that
node).
Then I run a simple test on a single node with 2 places, the code and
the results are shown as below. It shows that the RX/TX of sending an
array with size 10,000 is the same as 100,000,000. Then I just doubt
that the X10_TRACE_RXTX can not catch the RX/TX of asyncCopy, is that
right? Is there any method that can record the RX/TX between each
place in this situation?
Thanks in advance!
Long
public class test {
public static def main(args: Array[String]) {
val N:Int=Place.MAX_PLACES;
val NUM:Int=Int.parseInt(args(0));
val r:Region=0..(N-1);
val d:Dist=Dist.makeBlock(r);
val receive=DistArray.make[RemoteArray[Int]](d);
var sent:Array[Int]=new Array[int](NUM);
for(i in 0..(NUM-1)){
sent(i)=i;
}
val p1=Place.place(1);
at(p1){
receive(here.id)= new RemoteArray(new Array[int](NUM));
}
Array.asyncCopy( sent, at (p1) receive(here.id));
Console.OUT.println(NUM+" is done");
}
}
