Hi all,
I was playing with Leader-follower zippered iterator. I have a counter
iterator given below. My aim is to make the leader send numbers low..high
one by one to follower which yield them , one by one. (Hope it is okay?)
//serial version
iter counter(low:int,high:int)
{
writeln("This is from serial");
for i in low..high do yield i;
}
//creating Leader-Follower
iter counter(param tag: iterKind,low:int,high:int) where tag ==
iterKind.leader
{
writeln("This is from leader");
for i in low..high
{
var r: range;
r=i..i;
r.stridable=false;
yield r;
}
}
iter counter(param tag: iterKind,low:int,high:int,followThis) where tag ==
iterKind.follower
{
writeln("This is from follower");
for i in followThis(1).translate(low) do yield i;
}
var A:[1..10] int;
forall (i,j) in zip(counter(21,30),A) do
j=i;
writeln("\n\nA after forall zippering is",A);
Which when compiled gave the error
myleaderfollower3.chpl:13: In iterator 'counter':
myleaderfollower3.chpl:24: internal error: PRI0162 chpl Version
1.12.0.2bb0f9c
