I'm trying to understand how to code the distributions and arrays. Can
someone explain what's going on here?
This code compiles and executes.
class ComplexArrayDist {
public static def main(args: Rail[String] ) {
var region: Region{rank == 1};
region = [0..9];
var dist: Dist = Dist.makeBlock(region,0);
var complexArray: Array[Complex](region);
complexArray = Array.makeVar[Complex](region,
((p):Point) => new Complex() );
for (var i:Int = 0; i < 10; i++){
complexArray(i) = new Complex(0,(i as double)/((i+1) as
double));
Console.OUT.println(complexArray(i));
}
}
}
But this code won't compile.
class ComplexArrayDist {
public static def main(args: Rail[String] ) {
var region: Region{rank == 1};
region = [0..9];
var dist: Dist = Dist.makeBlock(region,0);
var complexArray: Array[Complex](dist); //changed from region
to dist
complexArray = Array.makeVar[Complex](dist, //changed from
region
to dist
((p):Point) => new Complex() );
for (var i:Int = 0; i < 10; i++){
complexArray(i) = new Complex(0,(i as double)/((i+1) as
double));
Console.OUT.println(complexArray(i));
}
}
}
