This original mail asked something in addition:
What is the difference between
for k in j+1..n
{
a[k][j] *= aijmax;
}
and
[k in j+1..n] a[k][j] *= aijmax;
The first is a serial for loop while the second is a parallel forall loop.
'[<ind> in <iter>]' is essentially shorthand for "forall <ind> in <iter>"
in Chapel.
a[j+1..n][j] *= aijmax;
... The last says
u.chpl:69: error: halt reached - array index out of bounds: (1)
This one touches on the response I just sent you. Think of this as
being similar to:
var b: [j+1..n] a.eltType = a[j+1..n];
b[j] *= aijmax;
