Hi
Here is what I got running your program on a PPC machine (SLES11) with 4
Places
at Place print
3 3 3 3 3
print at Place
3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3
Finished
3 3 3 3 3 3 3 3 3 3 3 3 3 3 3
It seems the "missing elements" are flushed out when the program
terminates. Also note I'm using the latest X10 compiler -- I didn't try
2.1.2 version though.
As to your second question to copy data from DistArray to Array, I don't
believe there is an easier way (than assign value element by element).
However, in DistArray there is a protected field chacheRaw that is of type
IndexedMemoryChunck, which can be used to copy or construct Arrays. Unless
you're building additional classes to array library, this field,
unfortunately, is not accessible.
Cheers,
