Hi everyone,
Thanks for helping me on previous messages (especially Igor).
Below are 2 versions of a test (defining and accessing a distributed array on
several places).
This is a variation of an example code from X10 distribution
(EncapsulatedArray2D).
The first version is (apparently) working well but the second one launches
several x10.lang.BadPlaceException.
The differences are :
- first version : the distributed array is created and accessed only from the
static main function
- second version : the array is now a member of the class containing the main
function. It's created inside the class constructor and accessed from other
class method.
Thanks a lot for any suggestion.
Marc
