parallel processing - Port old X10 Example to version 2.5 -

i have old x10 illustration in class i'm trying compile.

import x10.array.array; import x10.io.console; ... public static def main(args: array[string](1)) { val regiontest = 1..12; val testarray = new array[int](1..12, (point)=>0); ([i] in testarray) { testarray(i) = i; console.out.println("testarray("+i+") = " + testarray(i)); } }

unfortunately seems outdated. figure out myself have write public static def main(args:rail[string]) now. definition of val regiontest = 1..12 seems ok. syntax array must wrong, next lines maybe too. tried prepare this guide, did not succeed.

my setup working, initial class in new x10 eclipse ide project runs.

could help me port version 2.5.x?

there number of non-backward-compatible changes in x10 version 2.4, require code changes - see guide "porting x10 2.4".

your illustration updated follows:

import x10.regionarray.array; import x10.regionarray.region; import x10.io.console; .... public static def main(args:rail[string]) { val regiontest = region.makerectangular(1..12); val testarray = new array[int](regiontest, (point)=>0n); ([i] in testarray) { testarray(i) = int; console.out.println("testarray("+i+") = " + testarray(i)); } }

this demonstrates number of of import changes:

(lines 1--2) general-purpose array classes have moved x10.array bundle x10.regionarray. these classes no longer imported default. (lines 6--7) there no implicit type conversion longrange (1..12) region. region object must explicitly constructed , passed x10.regionarray.array constructor. (line 7) default integral type long instead of int. int literal must suffixed character 'n' in '(point)=>0n'. (lines 8--9) index type array classes has changed int long (to back upwards big info structures). hence exploded point iterator for ([i] in testarray) yields i:long instead of i:int - means cast i int required when assigning int array element on line 9.
